Abel Makura has been appointed Association of Mine Managers of Zimbabwe (AMMZ) vice President.

The Mining Systems and Innovation expert who is a section Manager at Anglo American-owned Unki Platinum mine was voted vice President at the ongoing AMMZ Annual general meeting and Conference currently underway at Elephant Hills resort in Victoria Falls.

Famed for developing innovative solutions, Makura developed a mining system for the achievement of a record 4000 square meters in a month at Anglo-American’s Unki Mine. The system is based on creating synergies between the key value drivers in the mining production cycle (drilling, support and lashing) and being able to sweat the asset by utilizing every bit of available time in the 24hr day.

Makura replaces Innocent Guvakuva. He deputises Bulawayo Mining Company’s Elton Gwatidzo who has been re-appointed President until the end of the 2023 year.

Mnangagwa commissions US$67 million central shaft

0

Today President Emmerson Mnangagwa commissioned the central mine shaft at Blanket Mine which is part of Caledonia Mining Corporation‘s US$150 million investment into the Gwanda-based gold mine.

US$67million went into the construction of the central shaft, while US$14 million went into the construction of the mine’s 12-megawatt solar plant which has since been connected to the national grid.

Commissioning the mining shaft, President Mnangagwa said besides the positive impact on the province’s Gross Domestic Product (GDP), the newly constructed plant will create more jobs from the current 500 to 1600 workers, while revenue is set to shoot up to US$148 million dollars from US$123 million.

“I challenge other mining houses to increase investment in their operations for the realisation of maximum value from our mineral resource base for the good of the economy and our people in general. As the government, we have made a bold decision to ensure that every citizen of Zimbabwe benefits from our natural resource endowment, now and into the future,” Mnangagwa said.

“Let me take this opportunity to confirm and advise all mining houses that my government does not accept royalties in US$ anymore, what we want is a fraction of that, so that we build our mineral reserves and benchmark our local currency against our stock of minerals as we also safeguard the interest of our future generations using our God-given resources. This is a game changer in the development of our country and I take pride in this development,” the head of state added.

President Mnangagwa also spoke about the need for the country to invest more in innovation as the country focuses on accelerated industrialisation.

“In line with Vision 2030 and the National Development Strategy, greater effort should be put towards the value addition and beneficiation of our mineral resources and other primary products. We cannot, as a country continue to be exporting primary products including concentrates. Our people must fully enjoy the benefits of moving up the value chain such as increased profitability and terms of trade as well as employment and empowerment opportunities,” noted the President.

With the mining industry being the country’s primary foreign currency earner, the increase in production by the Blanket Mine not only brings hope to the country but also feeds into the target of a US$12 billion mining economy by the end of 2023.

The 1200-metre shaft which gobbled in excess of US$67 million will see the mining giant’s gold output jumping from less than a quarter of a tonne per annum to 2.4 tonnes per annum.

In his statement, Caledonia Chief Executive Officer Mr Mark Learmonth commended efforts to make Zimbabwe an attractive mining jurisdiction.

“The increase in gold output will benefit all stakeholders in Blanket mine through increasing employment, higher profitability and increased contributions to the fiscus. Your Excellency, I would like to commend your government for continued efforts to make Zimbabwe a more attractive mining jurisdiction. This work is not in vain as evidenced by expanding mining output as well as Zimbabwe’s shortlisting as one of the most improved mining jurisdictions in the world,” said Learmonth said.

Industry captains who attended the commissioning of the shaft commended the Mnangagwa-led government for the path it has taken in transforming the mining sector.

Chamber of Mines Chief Executive Officer Mr Issac Kwesu said the development will see growth in mineral export.

“When you look at this project it means we expect growth in the mineral export. We expect an increase of 17% in gold only, coming from  the construction of this central shaft and this will take us to another level and the industry will never be the same again.”

Mines and Mining Development Minister Hon Winston Chitando said the shaft will see Blanket increase production.

“I am pleased to tell you that, the central shaft which is one of the deepest in the country will enable Blanket mine to increase production, which in turn is a step towards the attainment of the US$12 billion mining industry by 2023. The economies of scale arising from the central shaft will contribute to managing costs on this mine,” Chitando said.

Kamativi Mining Company (KMC) is rapidly spearheading its exploration drive to transform the former tin mine into one of the biggest spodumene and Petalite ore body in Zimbabwe.

Rudairo Mapuranga

Recently Mining Zimbabwe visited the mining site to assess the progress of the potentially biggest lithium-producing project in the country and witnessed 8 Diamond drill rigs drilling at different locations to delineate the potential deposit.

Lithium samples

The exploration drilling at Kamativi Lithium Project is core drilling where samples of up to 300 m are being packaged for transportation to be tested. According to the site geologist at the KMC Miss Rutendo Chiota from the Midlands State University (MSU), some of the results have been submitted to the world-renowned geological group (Joint Ore Reserves Committee) JORC and KMC is currently awaiting a preliminary report.

According to Miss Chiota, the pegmatite ore body according to current results is going down to 250m down or more while the belt seems to be stretching for kilometres beyond the mining lease.

Ms Rutendo Chiota

The Drilling process penetrates deep into the ground and brings up samples of whatever is found are collected. If there is any mineralization at given points far beneath the surface, drilling can give a definitive answer by identifying available minerals, their quantities and location.

Between September 2021 and March 2022, Phase-one drilling commenced with 38 holes being drilled to the depth of 2140m . Phase-one drilling focuses on open-cast areas with shallow holes for Open Cast Mining.

Between April 2022 – June 2022, Phase-two drilling commenced and KMC managed to drill 28 holes of 5000m. The drilling was for underground mining and Mineral Processing research is still underway.

Phase-two detailed drilling of 100 holes of around 15000m is being carried out with detailed exploration for underground mining and resource report and feasibility study to be expected after drilling is completed.

To date, 4900m have been drilled from late September 2022 using the 8 rigs on site. Exploration is going to be upscaled by an additional 4 rigs which are expected to be on-site by early November 2022 (bringing the total number of rigs on-site to more than 12 rigs) in mid-November. The work will lead to locating the first mining area, designing for mining and carrying out mining activities.

“It is important to point out that we are using the Core drilling method. The core is an intact sample of the underground geology, which can be examined thoroughly by the geologist to determine the exact nature of the rock and any mineralization. To quantify the mineralization, and to define the shape, size and metal content of the deposit, a step-by-step procedure in exploration activities is required. At every step of this procedure, the geologists examine the information at hand, to recommend continuing the exploration efforts or not.

The objective is to be fairly certain that the deposit is economically viable by providing detailed knowledge of geology for a clear financial picture. Ore is an economic concept, defined as a concentration of minerals, which can be economically exploited and turned into a saleable product,” Executive Deputy General Manager Mr Jack Ye said.

Core drilling is also used to define the size and the exact boundaries of mineralization. This is important for determining ore grades being handled and vital for calculating the mineral reserves that will keep the mine running in the future. A strategically placed underground core drilling operation may also intersect new ore bodies in the neighbourhood.

The type of lithium dominant at KMC

According to Chiota, preliminary sample results have shown encouraging results for the mine hosting high-grade lithium spodumene, petalite with the mine having the potential to become one of the biggest lithium producers in Africa.

Spodumene is an essential supply of lithium to be used in ceramics, cell phones and car batteries, medicine, Pyroceram and as a fluent substance.

With the rise and popularity of Electric Vehicles (EVs) spodumene has become the most important commodity in the world with nearly all battery producers looking for mines that can supply them uninterruptedly spodumene for the future of the transport sector.

With Zimbabwe aiming to achieve a US$12 billion mining industry with the lithium industry expected to produce an annual revenue of US$0.5 billion annual revenue, KMC will have the potential to become one of the country’s biggest revenue generators.

Fidelity Gold Refinery opens a gold-buying office in Makaha

0

Fidelity Gold Refinery (FGR) has opened a gold-buying office in Makaha, Mutoko.

Makaha is an area known for small-scale mining activity and for years it had no Fidelity Agent near the area or nearby Mutoko centre. Miners were expected to travel to Marondera the capital of Mashonaland East province 148km away to sell their gold. Logically it was highly unlikely a miner would go that far to sell only a gram of gold as most if all the proceeds from their gold will be used up just by transport costs.

In a statement, the country’s sole buyer delivered the pleasant news, promising those who deliver instant cash.

“For your convenience Mutoko (Makaha) miners, we have opened a buying office at the Makaha shopping centre (Shije Building). Deliver your gold and get instant cash,” the statement read.

Fidelity has vastly improved on cash payments since the takeover of the current General Manager Mr Peter Magaramombe.

The coming in of Magaramombe has seen improved deliveries of gold to the country’s sole buyer and exporter. Gold deliveries to Fidelity Gold Refinery in the eight months to August 2022 grew by nearly 41 per cent to 22,3 tonnes from 13,2 tonnes in the same period a year ago.

The establishment of new gold buying centres across the country will boost deliveries and continued instant payments from Fidelity will surely aid in the attainment of the us$12 billion mining industry by 2023.

Cossy Rules awarded Philanthropy doctorate

0

Businessman and miner Cosmas Dhaka popularly known in the mining circles as Cossy Rules has been awarded an honorary Doctorate of Humane Letters Degree for the advancement of humanity by the International Institute of Philanthropy.

Rudairo Mapuranga

The Kadoma-born businessman, community leader, arts promoter and one of the most successful miners who own Cossy Rules Holdings is known throughout the country for his philanthropy work.

During the Covid-19 pandemic-induced lockdown Dr Cosmas Dhaka together with the Kadoma Miners Association donated food and PPE to many groups of people in Kadoma to reduce lockdown made stress and deaths in the city of gold.

Dr Dhaka has also invested in education and has over the years paid school fees for less-privileged and brilliant children at Waverly Primary School in Kadoma and also donated stationery.

Cossy Rules Holdings was awarded Mines and Mining Industry Company of the year at the Zimbabwe Business Awards held in Harare on 28 October 2022.

Speaking to Mining Zimbabwe Cossy said he had a passion for empathy and regard for the less privileged and a desire to make a difference in other people’s lives

“It is my duty to bless others as I have been blessed. I also support the government’s 2030 vision as this will indirectly or directly reduce poverty in the country,” Dr Dhaka said.

Dr Dhaka is also currently furthering his studies with a local university.

Premier ready to construct Zulu pilot plant

0

Premier African Minerals is geared to construct its pilot plant at Zulu Lithium and Tantalum project in Fort Rixon as the area for the construction of the plant has already been cleared and is ready for commissioning.

Rudairo Mapuranga

In June, Chinese-owned Suzhou TA&A Ultra Clean Technology company agreed to provide a pre-funding amount of US$34,644,385 (“Pre-Payment Amount”) to enable the construction and commissioning of the large-scale pilot plant at Zulu.

Commenting on the prepayment agreement Premier African Minerals CEO George Roach said Suzhou TA&A pledged to dispense an initial US$3 MILLION into the commencement of the pilot project.

“Upon the signing of the Agreement, US$3,450,000 has been made immediately to Premier to commission the securing of the pilot plant. The remaining balance of the Pre-Payment Amount will be paid in one lump sum following the completion of the transaction documents. Both Premier and Suzhou TA&A have agreed to use their best endeavours to complete the definitive transaction documents within one month of the Agreement failing which on written notice by Suzhou TA&A, Premier will be required to immediately refund the amount of US$3,450,000 to Suzhou TA&A from existing funds held by Premier,” he said.

Repayment of the Pre-Payment Amount will be made by Premier from all residual funds from invoices raised by Suzhou TA&A from each monthly Accounting Period following the deduction of agreed Deductible Expenses incurred at the Zulu Project (being all costs and expenditures incurred including government royalties) and management fees to be paid to Premier until the Pre-Payment amount has been fully refunded.

The Pilot Plant

The pilot plant to be commissioned will utilise state-of-the-art sensor-based ore sorting technologies that will facilitate the separation of run-of-mine material into components and in so doing, likely increase available capacity in the flotation recovery circuits, where lithium minerals are recovered. Ultimate production and recoveries are a factor of many variables, and the pilot plant is likely to assist in dealing with these variables due to the inherent flexibility of the use of multiple ore sorters. Stockpiles of tantalum, petalite and Mica/lepidolite-rich material will facilitate further test work and flow sheet development to ensure that this material is truly inventory for later profitable recovery.

The pilot plant has a nameplate throughput of up to 190 tons per hour, however, it is planned to run at a more conservative 140 tons per hour at inception. At this rate and based on a 3-year life of the pilot plant operations only, excluding plant upgrades, tantalum recovery, petalite production and any other revenue, a series of sensitivities indicate a robust project and an assurance that Premier will become cash generative from the time of the first shipment.

Blanket Mine solar plant starts generating power

0

Caledonia Mining Corporation Plc is pleased to announce that the new solar plant at Blanket Mine from yesterday started to generate power for the Gwanda-based miner.

In recent years this supply has been subject to load-shedding and unstable power, which has economic and safety implications for an underground mine such as Blanket. During outages or low voltages, the power supply at Blanket had to be supplemented by standby diesel generators to enable uninterrupted mining and capital operations.

Diesel-generated electricity is expensive, subject to an unpredictable supply of diesel and creates an unfavourable environmental footprint. Recognising the economic, environmental and logistical challenges of running large-scale diesel generators for extended periods, Caledonia started constructing the 12.2 MWac solar plant late in 2021.  As of yesterday, the solar plant will be providing power to Blanket; in due course, it is expected that the solar plant will provide approximately 27 per cent of Blanket’s average daily electricity demand.

Commenting on the announcement, Mark Learmonth, Chief Executive Officer, said the project will cover 21 per cent of Blanket’s on-mine costs.

“I am delighted that the solar plant is connected to the Blanket grid and from today Blanket will start to receive some of its energy directly from solar.

“With 21 per cent of Blanket’s on-mine costs relating to energy usage, this solar plant is a very important project for the company as it will improve the quality and security of Blanket’s electricity supply and provide environmental benefits through cleaner energy.  The solar power will displace more expensive power from the grid and from the diesel generators and is expected to reduce Caledonia’s consolidated cost per ounce of gold produced by approximately $37.”

Blanket has been hailed by Zimbabweans in the mining business as one of the best miners in the country.

AMSZ pledges to support School of Mines Survey Department

0

The Association of Mine Surveyors of Zimbabwe (AMSZ) has pledged to support the Zimbabwe School of Mines (ZSM) Survey Department to enable the country to establish a distinguished world-class Mine Surveying industry.

Rudairo Mapuranga

The Zimbabwe School of Mines is known for being one of the best mining schools in Southern Africa and Africa at large, however, like many institutions in Zimbabwe, the school has been facing challenges due to the country’s economical challenges the country is facing.

Speaking at the AMSZ Annual Conference held at Caribbea Bay Resort in Kariba on Friday, ZSM HOD Survey Department Linton Mapasure said the school of mines has been investing in modern technologies to come up with world-class surveyors however, due to challenges in the country’s economy the equipment sometimes would not be enough for all the students thereby creating learning challenges.

“For the purpose of training, we have been investing in modern technologies. However, the equipment-for-student ratio is very low, we are therefore appealing to well-wishers to assist with equipment. We are also facing challenges for student attachment, therefore we are calling for companies to work with our students,” Mapasure said.

Speaking on the sidelines of the conference, AMSZ President Gabriel Mwale said his Association was willing to help and work closely with the school of mines survey department if they are formally engaged.

He said he was also going to work around in his personal capacity to ensure that some of the challenges of the department are attended to.
