Hwange Communities raise concern over Deka river pollution

0

COMMUNITIES in Hwange who, for years, have been affected by Deka River pollution, have raised concern over coal mining companies’ failure to address the problem and reneging on their promise to provide safe water.

This was revealed recently by a taskforce comprising of Hwange district administrator, Hwange Rural District Council, communities from affected areas and other interested stakeholders at a feedback meeting organised by Basilwizi Trust.

The taskforce, which is looking into the pollution problem, was set up in March this year.

Villagers said the mining firms had reneged on honouring their pledge to drill boreholes leading to loss of livestock due to the acidity of the water.

The mining firms have been blamed for the death of hundreds of fish in December last year.

Hwange Colliery Company, Zimbabwe Power Company, Chilota and Sandledge Mining (formerly Coalbrick Mine), who are discharging effluent into the river, were summoned by the taskforce and pledged to, among other things, investigate the source of pollution and drill three boreholes each in the affected communities.

Preliminary studies conducted by the Environmental Management Agency (EMA) revealed that acid mine drainage (AMD) from the mining activities in the area was affecting aquatic life. Other pollutants from mining activities such as coal dust or fines were cited as contributors.

AMD refers to the outflow of acidic water from a mining site. In most cases, this acid comes primarily from oxidation of iron sulfide, which is often found in conjunction with valuable metals.

“We are disappointed at the pace these companies are taking in addressing access to water issues, which they pledged to do sometime in March after effluent was discharged into the Deka River, which is an important water source for us and our livestock. Fish continue to die and our livestock is also being affected by this pollution. The water is not safe to drink, bath or wash as it leaves skin itching, which has forced us to travel distances of between 3km and 5km to access drinking water,” Mashala village head Patrick Nyoni said.

Nyoni said they need to find lasting solutions to stop pollution. He said environment authorities took samples of the water, which was sometimes yellow or dark green in colour, but have not released the results.

Rosemary Shoko from Chachachunda said women were the most affected, as they were in constant contact with the water.

“This a crisis that needs urgent attention, and the delay that is taking place has become a great worry to us. We as women are the most affected as we have to walk for several kilometres to access clean water, and since our primary food source has been polluted, it is us who have to look for alternative relish. We are very worried about our health, considering the tenderness of women skin which when exposed to the contaminated water from the river becomes itchy. We have continued to say these companies have been gambling with our lives, polluting the water without restraint. What are we going to eat when our animals are also dying from this calamity?” she said.

Communities in Chachachunda, Zvabo, Mukuyu, Mashala and Mwemba, home to a population of about 1 200, blamed the mining companies’ poor rehabilitation systems for the catastrophe.

Acting Hwange district administrator, Simbarashe Kayela said the companies had committed to start drilling boreholes in December.

“Your concerns are noted, and I want to assure you that the DA’s office is doing everything in its power to ensure that boreholes are drilled as per pledge. So far, I can confirm that Hwange Colliery has been rehabilitating some of the boreholes that had broken down long back as part of its short-term plan to resolving the problem. I’m happy that they have put tentative timelines to start drilling, which is a positive development, though the process has been slow. It’s not going to be a one day activity, but it’s an ongoing process of engagement,” he said.

Kayela said ZPC would take advantage of a second pipeline which is going to be constructed under the Stage 7 and 8 expansion schemes of the power station to connect taps to the communities.

He said Sandledge had asked for drilling quotations and would commence work before monthend, while Chilota has not been mining for sometime and are yet to advise.

Meanwhile, HRDC said it was engaging mining companies with a view to finding a permanent solution that would eliminate pollution.

EMA revealed that similar patterns were experienced in 1996 and 2007. The agency said there was need for long term commitment such as the installation of a treatment plant to stop pollution.

“We have engaged companies that are dumping effluent into the river to do so after treating it. There has been compliance in that regard. However, it has also been noted that AMD, which finds its way into the river, is the main culprit causing the deaths of fish. There is need for concerted efforts in establishing effective treatment mechanisms such as installing a treatment plant downstream,” EMA Matabeleland North provincial manager Chipo Mpofu-Zuze said.

Though the Environment Management Act has a provision for the setting up of an Environment Fund, which is meant to assist in cleaning up, rehabilitating degraded and polluted environments, nothing has been done to utilise it in addressing the Hwange issue. Setting up of the treatment plant reportedly costs around $30 million, a figure most companies cannot afford.

Pelgin introduces a new model truck in Zimbabwe

0

Last week Gary Moorcroft, the Managing Director of Pelgin Consultancy Services, handed over a LGMG Rigid Dump truck to Collin Campbell of Pomona stone quarries at a ceremony held at Pomona Stone Quarry in Harare.

 

The truck which is a LGMG MT60 Rigid Dump Truck, the first MT60 model to operate in Zimbabwe, offers a payload of 45 tons, and is ideally suited for medium size mines and stone quarries. However, there are a number of smaller LGMG MT50 and larger MT86 Models already operating on chrome mines in the Country.

Pelgin, are confident that this product range is set to become a major solution for mining operations looking for a productive, but price competitive solution for their haul requirements. There are a number of medium to large projects that Pelgin are currently working on for the supply of the LGMG Range of equipment, and Zimbabwe will soon become a major destination for these products.

According to Pelgin, the truck handed to Pomona Quarries LGMG MT60 Truck, has a payload of 45 tons, and is being loaded with a Volvo EC700 Excavator, fitted with a 4.1m3 rock bucket.


Pelgin is proud to handover the first LGMG MT60 Rigid Mining Truck to Pomona Quarries in Harare.

“This is an ideal match, and the excavator is needing 7 passes to load the truck, which hauls the blasted grey granite in the pit to the primary crusher. The truck is standard, but does include the more robust tyres fitted with 15.00R25 E4 Tyres. This unit has a 20m3 bin purpose built to take the higher SG rated material. Standard bin size for the 45 ton payload is 25m3. The Body is made of NM400 steel and is designed to take the harsh conditions found in mining and quarrying operations. Pelgin also provided Pomona with a LGMG Technician to offer operator training as well as maintenance training.” Said one Pelgin consultant member.

Pelgin are the official Volvo CE Dealer in Zimbabwe and have become a major source of equipment for the mining and construction industries in Zimbabwe. In addition SDLG is also offers by Pelgin, a Company that is jointly owned by both Volvo CE and LGMG. This gives Pelgin the unique advantage of offering the full spread of mining and construction equipment that offers complete solutions to their customer base. There is no doubt that LGMG will become a popular Brand for Pelgin in Zimbabwe as the mining industry embraces them in the years to come.

Pelgin also offer LGMG MT86H model, which is a 55 ton payload. It is extremely popular in larger mining operations around the world, reports have it that, over 3 000 of these units are sold each year. LGMG can offer up to a 70 ton payload model, for example their LGMG CMT106. The truck is a dedicated rigid off road mining dump truck, built from the ground up. LGMG trucks are tougher, more productive and dedicated to harsh mining conditions. This, coupled with being extremely price competitive, make it a viable alternative not only to generic tipper trucks but also the more conventional, yet pricey, articulated and rigid mining trucks available.

Gold prices decline

0

Gold prices inched lower yesterday as the dollar held firm below a 19-month peak on safe-haven demand amid concerns of a global economic slowdown, and as investors awaited cues on US interest rate hikes from a Federal Reserve meeting this week.

Spot gold was unchanged at $1,238.12 per ounce at 0820 GMT. US gold futures rose 0.1 percent at $1,242.1 per ounce.

“Gold’s move today is purely dollar-driven,” said Kunal Shah, head of research, Nirmal Bang Commodities in Mumbai, India.

“Ahead of the FOMC (Federal Open Market Committee) meeting, we are going to see some downward movement . . . But the fact remains that the underlying strength in gold is likely to continue.”

Markets will closely watch the future trajectory of US monetary policy at the Federal Reserve’s tomorrow to Wednesday meeting where the board is set to raise interest rates by 25 basis points.

“Markets will rally on the back of dollar weakness after the central bank signals a more dovish stance, but the advance will fall back quickly as global growth concerns reassert themselves,” INTL FCStone analyst Edward Meir said in a note.

Prospects of higher US interest rates are negative for dollar-priced gold as they raise the opportunity cost of holding the bullion.

The dollar index, which measures the greenback against other major currencies, was just below the 19-month high of 97,71 hit on Friday

Weaker-than-expected economic data from China and Europe and fears of a possible US government shutdown enhanced appeal for the US currency, which has played the role of a safe-haven asset in recent times.

Spot gold is biased to break a support at $1,232 per ounce, and fall to a lower support zone of $1,224-$1,228, according to Reuters technical analyst Wang Tao.

Meanwhile, hedge funds and money managers switched to net long position in Comex gold in the week ended December 11, the US Commodity Futures Trading Commission (CFTC) said on Friday.

This was the first time gold speculators held a net long position since July, and the strongest since June.

“Uncertainties of the trade war are still weighing on the market,” said Dick Poon, general manager, Heraeus Metals Hong Kong Ltd.

“It is getting close to Christmas time, so it is getting super quiet in the market. Investors reduce their inventories as much as possible before the year ends.”

Among other precious metals, spot palladium rose 0,9 percent to $1,248.44 per ounce.

Silver climbed 0,2 percent to $14,59 per ounce, while platinum declined 1 percent to $779,50 per ounce. — Reuters.

Moti Group addresses concerns of wrestling claims from ASM

0

The Moti Group (MG), a mining company owned by the South African business magnate, Zunaid Moti, has begun addressing concerns raised by a section of small-scale chrome miners who accused the company of indirectly trying to wrestle their claims from them.

MG has chrome mining operations in the Midlands Province, but it was accused by small-scale miners of moving around the country collecting various coordinates of claims belonging to small-scale miners without their knowledge.

It was alleged that MG was doing this under its $50m Zimbabwe Motivation Mining (ZMM) programme, aimed at capacitating small-scale chrome miners across the country.

But the small-scale miners protested, saying it was a violation of their rights as the ZMM deal had not come to fruition.

The ZMM programme is a brainchild of MG and its local partners, Sakunda Holdings, which is owned by the business tycoon, Kuda Tagwireyi.

The programme is a 20-year mining deal with the government of Zimbabwe aimed at formalising and strengthening the small-scale mining sector in the country. According to MG, ZMM has since agreed an initial off-take allocation of $50m.

“It is widely understood that ZMM exists to support the livelihoods of miners, not take them away,’ says MG. This is why the programme has received so much interest and so much support since we launched our pilot earlier this year.

“We cannot work effectively with small-scale chrome miners if we do not understand and respond both to the expectations and apprehensions of the ZMM. We can confirm that we take no action without the explicit consent of our participants,” MG added.

MG said they have been in the field engaging and working with small scale miners in line with the ZMM project.

“We are taking time to ensure that all concerns are addressed. All our internal systems are ready and all supervision from the Ministry of Mines is in place so that we can launch ZMM fully, purchasing lumpy chrome direct from miners, giving them a stable and fair price and a certain route to market,” the mining group said.

The group said the ambitious projects needed to be thoroughly planned in order for them deliver on their promises.

Small scale chrome miners who requested anonymity told Business Times there was lack of clarity around the ZMM deal.

“As small scale chrome miners we are worried about the Zimbabwe Motivation Mining deal where we are of the opinion that Moti Group is looking at indirectly buying off our claims on the pretext of just purchasing chrome from us,” said one miner.

“The Moti group has even went to an extent of moving around the country collecting coordinates of claims without our knowledge and we think such an action is illegal and a violation of our rights.”

Under the programme, MG has highlighted that feedback from small scale miners on the pilot scheme has been positive and the programme will be supervised by the Ministry of Mines and Mining Development. The programme will initially work with small-scale chrome miners before expanding into gold and lithium beneficiation.

According to MG, information gathered on all potential participants will be shared with Government to help improve the understanding and oversight of the country’s small-scale chrome mining operations.

All miners included in the ZMM project will have goals set through their individual development plans.

MG said the ZMM will utilise existing infrastructure and technology to help improve the efficiency and safety of small-scale mining operations.

To improve safety, security and reach, ZMM will make use of satellite offices at which product can be deposited. ZMM will match the grade of each product with available market prices and will provide miners with 50 percent payment through the internal Real Time Gross Settlement platform and 50 percent through United States Dollar.

Artisanal miners to obtain substantial value

0

BUBI Milling Centre (Private) Limited has invited tenders for the construction of a carbon-in-pulp plant in Matabeleland North.

The milling centre is one of the many gold service centres earmarked to be set-up by the Government as it moves to ensure the yellow metal from small-scale and artisanal miners is sold through formal channels.

Bubi Milling Centre, a joint venture between Bubi Small-Scale Miners’ Association and the Zimbabwe Mining Development Corporation (ZMDC) was commissioned by Vice President Dr Constantino Chiwenga in July.

In a notice for tender invitation, Bubi Milling Centre said it was inviting applications from reputable, eligible qualified, experienced, and capable general building and engineering contractors to tender for the proposed project.

“Completed forms must be delivered to the Bubi Milling Centre premises (44 kilometre peg from Bulawayo along Nkayi road) by Wednesday, 19 December.

“This tender document provides the requirements and the scope for this project, which is required to access the suitability off the bids,” it said.

“The successful applicant will be required to deliver services in accordance with all the requirements of the project details.”

A carbon-in-pulp plant is an extraction technique for recovery of gold, which has been liberated into a cyanide solution as part of the gold cyanidation process.

The process was introduced into the mining industry in the early 1980s and carbon-in-pulp is regarded as a simple and cheap process.

The project shall also include all feed material test works, civil works, construction or installation of but not limited to ore bin, conveyances and ball mill among others.

In the past, small-scale and artisanal miners were failing to obtain substantial value from the ore delivered to private gold millers.

ZMDC facilitated a loan of $3,5 million from Fidelity Printers and Refiners for the procurement of machinery and various mining consumables for use at the centre.

The loan facility is expected to be repaid over a three-year period.

Zim to double platinum production

0

ZIMBABWE is on course to double platinum production by 2023 as well as value add the mineral through the construction of local base and precious metal refineries, Mines and Mining Development Minister Winston Chitando has said.

Zimbabwe, in line with President Mnangagwa’s Vision 2030 target, intends to grow its annual mineral exports earnings from the current US$2 billion to US$12 billion by 2023, and Government is working on a number of strategies towards attaining this target.

In an interview with The Sunday Mail Business on Friday, Minister Chitando said Government has so far received input which it is considering for incorporation into the new platinum development policy to be launched in the first quarter of 2019.

Zimbabwe, according to the World Platinum Investment Council, produced 480 000 of platinum in 2017.

Government also projects increased economic activity as the three major producers — Zimplats, Mimosa and Unki – all have plans of implementing value addition strategies, while the new investor, Karo Resources, has committed to constructing a refinery.

Platinum production involves mining of ore, production of concentrate, smelting of concentrate into ore, production of base minerals from a base metal refinery, and, finally, precious metals from a precious metal refinery.

Currently, the country’s largest platinum producer, Zimplats, is at matte stage, Mimosa is at concentrate stage of value addition and Unki has just finished construction of a smelter which will enable it to produce matte.

At present, both the matte and concentrate are shipped to SA for further value addition to extract final product.

Proposals by the Platinum Producers Association to jointly establish base and precious metal refineries are a significant step in fulfilment of Government’s value-addition drive.

Zim to get more from diamonds

0

TIRED of pocketing crumbs from the sale of raw diamonds that naturally fetch less on the global market, Government has launched an audacious bid to join the big league by wading into the value addition and beneficiation sector.

The thrust of adding value and beneficiating diamonds is captured in the diamond policy that was approved by Cabinet a fortnight ago.

In the period 2009 to 2016, rough diamonds were sold at between US$40 and US$80 per carat.

Sources say the bulk of the diamonds were sold at about US$53 per carat, depriving the country of meaningful economic value and sparked concerns that gems were looted by a small clique of bigwigs.

Last week, President Emmerson Mnangagwa indicated that it was time the country moved into the mega-bucks value-addition sector.

“This new (diamond) policy protects the national interest, while meeting the expectations of the Kimberley Process Certification Scheme,” said President Mnangagwa.

“The equity structure which the policy prescribes firmly secures our national interest. So, too, does its interest in and coverage of all stages of the diamond value chain, which are exploration, mining, processing, sorting and valuation, beneficiation and value addition, marketing, capacity building, security and compliance.

“. . . this means Zimbabwe must move and stay as close as possible to where real value is. This is the import of our diamond policy, which incorporates a valuation centre, a school of gem training, and a whole special economic zone for jewellery manufacturing and retailing.”

Statistics show that global rough diamond sales generate between US$15 billion and US$18 billion.

Rough diamond sales is the first stage of the diamond value chain, while cutting and polishing diamonds is the second stage, which fetches anything between US$20 billion and $24 billion.

On the upper rung of the diamond value chain ladder is the jewellery retail market, which attracts revenues of between US$70 billion and US$72 billion.

President Mnangagwa said it was imperative that the country taps into the billions of dollars that accrue from value addition.

“Clearly, the greatest value does not reside with the miner at Chiadzwa. Rather, it resides with the diamond trader somewhere in Antwerp, Surat, Tel Aviv or New York who dresses the customer’s finger,” he said.

This year, the Zimbabwe Consolidated Diamond Company (ZCDC) has a stretch target of 3 million carats.

Between January and October, ZCDC had hauled 2,4 million carats, which is considerably above the 1,8 million carats mined all of last year.

Considering that diamond occurrences have been noted in most parts of the country, including Midlands and Matabeleland South, analysts say it is imperative that value addition is expedited to ensure more revenue is generated.

Value addition cuts across all minerals.

The 2019 National Budget underscores the need for value addition and beneficiation.

Finance Economic Development Minister Professor Mthuli Ncube said Zimbabwe’s thrust is to add “value and beneficiate more through processing and refining of minerals and link processed and refined minerals to the manufacturing sector in order to industrialise”.

Government is finalising the Mineral Value Addition and Beneficiation Policy designed to improve domestic smelting and refining, to take advantage of the immediate scope for income and exports generation offered by minerals such as platinum, chrome, lithium, nickel, diamond, copper, gold and coal.

As value addition gathers pace, the platinum sector has already complied with Government aspirations, with President Mnangagwa set to commission Anglo-Platinum’s smelter at Unki Mine in Shurugwi this week.

“I am set to officially launch this much-awaited investment next week, thus enabling our mining industry to move one more step further up the platinum value chain,” said President Mnangagwa.

In 2014, Government directed the country’s three platinum mining firms — Zimplats, Unki and Mimosa — to construct a precious metal refinery to ensure local beneficiation to stem possible leakages of minerals amid fears the miners were not declaring all proceeds from other minerals associated with platinum such as gold.

The deadline to construct a platinum refinery was January this year.

Towards end of last month, Johannesburg Stock Exchange-listed Anglo American Platinum (Amplats) announced the completion of a US$62 million platinum group metal (PGM) smelter at Unki.

The smelter is expected to generate matte, a product that would be sent to Amplats’ South Africa’s base metals and precious metals refineries.

As at Wednesday last week, the price of platinum per ounce was US$834,90 while palladium, which is part of the PGMs, was fetching US$1 225,90 per ounce on the international market.

The palladium price was marginally lower than gold, which was selling at US$1 246,30.

With more platinum projects in the pipeline such as the US$3 billion Great Dyke Investments (GDI) — a joint venture between Zimbabwe and Russia — expected to be consummated when President Mnangagwa travels to Russia mid-January next year at the invitation of President Vladimir Putin, the Unki smelter will come in handy.

The US$4,2 billion Karo Resources platinum project is also taking shape.

Value addition of lithium is also set to start with President Mnangagwa earmarked to officially open the lithium carbonate plant situated in Kwekwe.

The lithium carbonate plant was installed by Australian-listed mining concern, Prospect Resources, which is set to create battery grade (+99,5 percent) lithium carbonate.

Prospect owns the US$52,2 million Arcadia Lithium Project in Goromonzi.

Bonnox – Efficient fencing that lasts

0

Bonnox is well renowned for their quality and fully galvanised fencing.

Already, many farmers are aware of Bonnox’s range of fine products: The “Money Saver”, “Close Mesh”, “Kombi
Fence”, “Square Mesh”, “Multi Fence” and “Flexi Fence” were all meticulously designed to provide for every possible
need. But what sets a manufacturer apart from the rest, is the ability to promptly observe and react to new trends and needs in the market.

The prefabricated fencing market in Africa currently needs a product which is inexpensive, as farmers are              currently required to be thrifty with their money. Therefore, Bonnox decided to introduce their “ Economy “ range. The only difference between this fencing and their existing “ Elite “ range, is that it is lightly galvanised instead of
fully galvanised. Now a farmer can compare “ apples with apples “ when comparing Bonnox with competitors’
fencing products.

“There are lightly galvanised wire fences on the market, but many of our clients ask for it under the Bonnox
brand name,” says Anita Gent, Director of Bonnox. “We therefore decided to also manufacture an economical version of the nine most popular products in our range of seventy products. This includes the “Money Saver”, “Close Mesh” and “Multi Fence” ranges of 1,2m, 1,8m and 2,4 m. This offers the farmer an inexpensive solution of
fencing for his stock, small and large game. In areas where the effects of the elements are not very harsh on wire fencing, this inexpensive Bonnox will still last for many years, but fully galvanised Bonnox is still recommended
for areas where the elements affect fences more severely As the “Elite” and “Economy” ranges look exactly the same, the labels on the existing “Elite” range are green while those on the economical range are royal blue. The price of the
economical range is only 75% of the price for the existing range, but it is still being manufactured with the same
Bonnox meticulousness and care. The wire still being from the same supplier.

Skip the middleman

“Any farmer can order our products directly from our factory in Sunderland Ridge, south of Pretoria, to simplify logistics and cut costs. This also means that the farmer can gain the best advice and support directly from the
manufacturer,” Anita says.

Bonnox makes sure that there is minimal or no lead time at the factory. Bonnox keeps stock of approximately
70 different fencing varieties to suit every customer’s requirements. Bonnox is continuously looking for ways to accommodate the farmer. “For every ten rolls of fencing a farmer buys, he gets one free,” she says. “On
top of that, we offer a 25% discount. Bonnox also provides erecting equipment at competitive prices which
makes fence erection a simple matter.

Young Zimbabwean Engineer Shines at an International Explosives Conference

0

A Zimbabwean Explosives Engineer, made history in San Antonio by becoming the only African and first Zimbabwean Engineer to present at this year’s prestigious International Society of Explosives Engineer (ISEE) conference. Moshen Jena, was one of the keynote presenters at the recently held International Society of Explosives Engineers 44th Annual conference on Explosives and Blasting held in San Antonio, Texas, USA. The conference was held from the 28th to the 31st of January, 2018. More than 1700 experts in the field of explosives engineering attended the conference which is the largest of its kind in the field of explosives engineering in the world.

Explosives Engineer, Moshen Jena Presenting at the ISEE 44th Annual conference.

The conference brings together blasters, engineers, manufactures, researchers, academia, government officials and industry leaders. A total of 90 papers were presented during the Technical sessions showcasing the latest technological advances in the field of explosives engineering. The conference provides a forum for the discussion of practical and technical information as well as presentation of the latest discoveries in the commercial explosives industry worldwide.

Moshen presented a paper entitled ‘The application of underground bulk explosives in polyethylene pipes for perimeter control’. The paper was basically a case study of the system for a period of four years at a platinum mine in Zimbabwe where the system has been successfully implemented. The paper was presented on the 30th of January in session 7-Underground blasting.

In his paper, Moshen focussed on a system of perimeter control which originated in Zimbabwe and now becoming a standard as more and more mines are adopting the technique as a cost effective way of controlling the perimeter walls. This system of perimeter control uses Underground Bulk System technology (emulsion explosives) placed in specially formulated Polyethylene pipe to decouple the bulk explosives.

The effectiveness of this method was evaluated using information obtained during routine blast audits and data supplied by the mines on half cast factors, over break and under break as well as analysis of data from Ground Penetrating Radar (GPR) Scans over a period of four years.

This method of perimeter control, has given the platinum miners in Zimbabwe a competitive edge in cost effective perimeter charging and blasting by simplifying the previously costly deployment of traditional barrels and other decoupled cartridges. The method has been adopted by all the platinum mines in Zimbabwe as it has proven to be a cost effective alternative of controlling the perimeter walls, along with other key benefits that relate to safety, productivity and effectiveness.

It was battle royal, as the young Engineer who turned 34 in January, shared the stage with other veteran international presenters from all over the world. When his time came, Moshen dazzled the attendees with his eloquence, expressiveness and knowledge of blasting science.

Moshen Jena went to St Faith High School in Rusape for his secondary education and studied Mining Engineering at the university of Zimbabwe. Currently he works for AEL Mining Services, a leading explosives manufacturing company as an Explosives Engineer.

Other notable presentations were from the opening Speaker and astronaut Mike Mullane who delivered a powerful message on an employee’s role in keeping themselves and their teams safe in hazardous environments during his talk entitled, “Countdown to Safety.” He used the space shuttle Challenger disaster to define this term, its safety consequences and how individuals and teams can defend themselves from the phenomenon. Ryan Brogden, a Principal Inspector of Explosives for the Department of Natuaral Resources and Mines in Queensland, Australia who also presented learnings from the Ammonium Nitrate Vehicle explosion that occurred at Angellara Creek. He was the lead investigator into the Angellara Creek Ammonium Nitrate vehicle explosion and now leads the National Working Party implementing the recommendations from the incident.

Besides the Technical papers that were presented, the attendees were taken through training on different technological advances in explosives and blasting industry and also had an opportunity to see exhibitions from the leading manufacturers and service providers in the explosives industry. In summary, the conference was indeed an opportunity to learn, connect and exchange experiences from the different parts of the world.
