Adavale gears up for a highly active exploration period

0

Adavale Resources has commenced mobilisation of a multi-purpose reverse circulation diamond drill rig following completion of the 9 recent HEM surveys conducted over the company’s Kabanga and Luhuma Nickel Projects located within the East African Nickel Belt of Tanzania.

The drill program will initially focus on 7 high-priority nickel target areas
within the Kabanga North-East/Luhuma extension, Kabanga East and Kabanga West Licences. The program will be subject to ongoing refinement based on drill results, field
assessments and the final processed data from the HEM contractor.

“I’m very pleased that having completed the recent comprehensive geophysical survey work, the company is now entering into a very exciting phase of drill testing multiple targets. We are preparing for a highly active exploration period in the December quarter and expect a similar level of regular updates to the market.” said Adavale’s Executive Director, David Riekie.

Adavale’s Technical Director, John Hicks stated that the company’s initial high-priority target drill program will focus on 7 broad target areas which encompass the HEM survey areas 1 to 4 and 7 to 9.The drill rig will initially mobilise to Kabanga West to evaluate the HEM areas 7-9, which are on a similar latitude to our neighbor’s 58Mt @ 2.62% Ni, Kabanga Nickel deposit.

“We will remain flexible to ongoing adjustments to the drill program based on ongoing field
assessment of drill locations, drill results and the receipt of all final processed HEM survey data from the contractor, which is due over the coming weeks. Interpretation and modelling of the HEM data therefore remains ongoing at this point.

“We plan to test a number of anomalies identified within the broader target areas with diamond drill holes up to 500m deep, typically targeted at deeper coincident gravity and EM anomalies. Shallower RC holes may be drilled into individual gravity anomalies, to confirm the presence of prospective mafic-ultramafic bodies at depth. Down hole electromagnetic (DHEM) surveys will be performed on most holes to aid ongoing drill targeting.” he added.

The current drilling program is scheduled to continue over the 3-month period to December 2022 and be reviewed for ongoing refinement and reassessment including extensions to the program, based on results and additional drill target locations.

IonicRE’s Makuutu project to scale up Uganda’s mining development

0

Uganda’s National Environmental Management Authority (NEMA) has approved the Environmental and Social Impact Assessment for IonicRE’s majority owned (51%) Makuutu Rare Earth Project in Uganda.

This vote of confidence positions the Makuutu Rare Earth Project as Uganda’s next mining development, set to unlock unprecedented social and economic benefit through mineral development. The approval follows a 9-month assessment by NEMA culminating in two large public hearings with over 3,800 registered attendees demonstrating strong governmental and local stakeholder support.

The Makuutu Rare Earth Project is operated by Rwenzori Rare Metals Limited (“RRM”), a Ugandan company which is 51% owned by IonicRE at present, with the Company moving to 60% ownership on the completion of a Feasibility Study supporting the Mining Lease Application expected to be submitted to the Ugandan government at the end of October 2022.

Tim Harrison, IonicRE’s Managing Director.

“This is a significant milestone and vote of confidence by the Government and community groups – signifying the pivotal role Makuutu will play in the social, economic development and growth of Uganda. The Project aspires to be a significant contributor over a long period of time in Uganda.

To employ and train directly from within the local communities, source from local businesses and create further improved services, leading to an overall improved quality of life across the districts that host the Project.” commented Tim Harrison, IonicRE’s Managing Director.

The mining lease application (MLA) will focus on the Makuutu Central Zone (MCZ), located within RL 1693, and will provide the basis for initial mining at Makuutu. This area contains an Indicated Resource of 259 million tonnes at 740 ppm TREO-CeO2. Pending the award of the MLA, expected in 2023, the Company, via RRM, will be working with Ugandan authorities on a Mineral Development Agreement (MDA) which will establish the fiscal terms for the mine development in Uganda.

“This Project will set its sights on becoming Uganda’s flagship sustainable mine. Our vision is that Makuutu will provide global customers with an alternative supply of magnet and heavy rare earth elements needed for a Net-Zero Carbon world for 50 years and beyond.” concluded Harris.

Akobo begins construction at Segele

Akobo Minerals has broken ground at its Segele gold mine in Ethiopia. This marks an important milestone on the path to gold production in early 2023.

 Jørgen Evjen, CEO of Akobo Minerals, stated:

“When excavation began today to remove the overburden at our mining site in south-west Ethiopia, it was the culmination of over a decade of tireless work for the company.”

“The next steps will be to undertake a short geotechnical evaluation, after which the ground supports will be set in place to allow for the safe establishment of a portal and the subsequent start of underground mining of gold in the first quarter of 2023 – marking a true landmark moment in the development of Akobo Minerals.”

As well as ongoing mining development activities, the coming weeks will see the progression of civil engineering and construction of support facilities. The company also expects major equipment for the processing plant to be received shortly.

The primary short-term tasks for the newly arrived contract mining staff from IW Mining will be to work with Akobo’s engineers to develop the box cut for the incline shaft. The box cut is a small open cut built to supply a secure and safe entrance as access to a slope to an underground mine.

In addition, the contract staff will be recruiting and training local staff to join the company as they advance towards production. Securing positions for those living in the local community is a key element in Akobo Minerals’ environmental, social and governance (ESG) program.

How can artisanal mining be transformed into legitimacy?

The answer is that we started Minexx to bring traceability, transparency and trust to the mineral supply chains and help improve efficiency, health and safety on site and protect the environment.

Why are minerals important?  Isn’t mining an old unnecessary industry? The industry of the future is technology surely? 

AUTHOR: Marcus Scaramanga, CEO & Founder, Minexx

Well minerals such as cobalt, copper, tungsten, tin and gold enable technology such as smartphones, electric cars and computers to function. In fact, smartphones contain about 60 different minerals in total. 

How do you meet the world’s demand for minerals whilst protecting people and planet?

The answer lies in capital for investment and semi-industrialisation. Access to capital for small mines in Africa is a major barrier to cleaner, fairer and a more transparent mineral supply chain. Mining sites in Africa need to purchase newer and better equipment to make their operations safer and more efficient.

South Africa’s mining industry: corrupt, lethal, and criminal

Currently there is no formal finance available for small-scale mining sites. The local retail banks do not serve the sector. Minexx is helping fill this gap in the market. Our finance also explicitly ties in the recipients to using the Minexx traceability and due diligence platform – increasing transparency and trust. 

In terms of improving efficiency and safety in the gold extraction sector, the use of mercury in processing can cause environmental damage and damage human health. Gold recovery rates using the more traditional sluicing techniques result in very low gold capture.

The ‘UN Minamata Convention on Mercury’ came into effect in 2017. It is named after the bay in Japan where, in the mid-20th century, mercury-tainted industrial wastewater poisoned thousands of people, leading to severe long term health conditions that became known as the “Minamata disease.” 

The Minamata Convention aims to control the supply of mercury, reduce its use, reduce its gasification and release; raise public awareness; and build the necessary monitoring and enforcement institutions to #MakeMercuryHistory. 

Minexx is proud to support this convention and the work we do helps deliver on its aims by providing finance to small mining sites so they can buy more modern and efficient equipment to phase out the use of mercury. 

The more modern mining equipment purchased with these loan funds means that more of the mineral (eg gold, tungsten and tin) is recovered, which leads to higher production to meet high demand, which leads to more money in miners’ pockets AND a safer workplace AND less negative environmental impacts.

I firmly believe Minexx can help the global mineral supply chains help meet the world’s demand for technology in a way that is fair for both people and planet. 

A miner at on one of our client’s mines in Burkina Faso recently put it: “The new equipment that the loan from Minexx helped us buy, helps us waste less and produce more from the material we dig up. But more than that it is safer to use – meaning less accidents.  The new equipment also means we can use less mercury which is tricky stuff to handle and can harm my fellow miners and me.”

IAMGOLD gears up for lifelong production at Côté

0

IAMGOLD Corporation has filed a technical report for the long life Côté Gold project in Canada which is expected to commence production in early 2024.

In 2019, SLR prepared an updated Côté Mineral Resource estimate which included the incorporation of additional drilling and updated mineralization wireframes, recognized local grade trends, eliminated the Fault domain, and used a new classification approach. Côté Measured and Indicated Resources total 365.5 million tonnes (Mt) at an average grade of
0.87 g/t Au, containing 10.20 million ounces (Moz) Au.

An additional 189.6 Mt at an average grade of 0.63 g/t Au, containing 3.82 Moz Au are estimated in the Inferred Mineral Resource category. The Mineral Resources are estimated at a 0.3 g/t Au cut-off grade, based on a gold price of US$1,500/oz Au, and have an effective date of December 19, 2019.

Exploration Status
Exploration programs to date have identified the Côté and the Gosselin deposits and have evaluated several nearby gold showings for their potential to be bulk-mineable gold deposits.
Exploration programs to date have been sufficient to screen many areas for the presence of a Côté-style deposit, with grid line spacing and general traverse spacing of <200 m (some areas <100 m spacing for traverse/grid line density). Litho-sampling and geological mapping is representative over much of the property land holdings, with some exceptions where glacial till and lacustrine deposits form thick mantles on the bedrock.

In areas of thick overburden, induced polarization (IP) geophysical surveys and diamond
drilling has helped screen these overburden-covered areas.

Capital costs spent on the Project prior to May 1, 2022, amount to $1,057 million. IAMGOLD has forecasted capital expenditures of $1,908 million for the remaining pre-production period. An additional $1,136 million of sustaining capital is estimated during the LOM.

Mining Method
Pit optimization parameters, financial assumptions, pit-shell selection, and mining dilution and recovery factors remain unchanged from 2018. The current Mineral Reserves are based on an updated mine design which optimizes pit phasing, ramp location, and waste stripping, resulting in negligible changes to Mineral Reserves compared to the previous estimate, and small reductions in waste.

Production Schedule
Pre-production commenced with contractor works in Q1 2021 consisting of overburden removal, supply of material for construction, and initial bench establishment. Contractor mining will continue for a period of two years until Q2 2023. In parallel, delivery and assembly of autonomous equipment has begun and owner mining will commence in Q1 2023. Mechanical completion, first gold, and commercial production are planned in Q4 2023.

The Côté deposit is planned to be mined in five phases included within the ultimate pit limit. The scheduling constraints establish the maximum mining capacity at 70 Mtpa and the maximum number of benches mined per year at eight in each phase. Additional constraints were used to guide the schedule and to obtain the desired results.

The company says that the project may still experience further increases in capital expenditures, although given the stage of advancement, the risk is reduced. In addition, construction and permitting delays could result in a prolonged schedule and increased project costs, and delay impacting mining activity or commissioning of the mill plant, which ultimately could impact the timing of production.

Developing sustainable roadmaps for the lithium and copper mining industry

0

Similarly, yet for different reasons, copper mining is also important, with experts forecasting major shortages in the years ahead. This is despite copper’s recycle value being quite high, where premium-grade scrap is said to have circa 95% of the value of the primary metal from newly mined ore.

Lithium mining projects are complex to manage, and often come in over-budget and off-schedule​. The involvement of multiple vendors, consultants, and internal ​stakeholders can lead to costly miscommunications​.

Further, a lack of common standards across various vendors can lead to extra engineering hours and project delays, and a lack of integration can impact future operations and plant efficiency. ​

Rockwell Automation solutions for lithium and copper mining (amongst other minerals), which in the form of Integrated Architecture can help increase operational efficiency, improve visibility and enable better decision making, enable a modernized and empowered workforce, allowing superior mine-to-market integration, while operational transparency and monitoring help to manage environmental concerns & community integrity.

On 20 July, Rockwell Automation and Mining Review Africa hosted a Webinar on how integrated systems and scalable analytics enable improved mine-to-market visibility and allow for better decision-making to build and operate more efficient and sustainable lithium and copper mines.

Barrick’s focus on quality orebodies delivers results

0

TSX-listed Barrick Gold Corporation replaced its depletion of gold mineral reserves by 150%, before acquisition and equity changes at South Arturo and Porgera, and improved the quality of its group reserve grade by 3% in 2021, the company’s annual reserve and resource declaration has reported.

Reported at $1,200/oz, attributable proven and probable mineral reserves now stand at 69 Moz at 1.71g/t, increasing from 68 Moz at 1.66g/t in 2020.

President and chief executive Mark Bristow said in a sector feeling the pinch of dwindling reserves and resources, successful exploration continued to replenish the company’s asset base and target pipeline, securing its business plans well into the future.

“While we look closely at all new business opportunities, we believe finding our ounces is always better than buying them. That’s why we’re still discovering real value at the end of our drill bits,” he said.

The growth was led by the North America and Africa & Middle East regions, which contributed over 8.4 Moz of attributable proven and probable reserve gains before depletion.

In North America, significant gains were driven by the completion of the updated feasibility study of the Goldrush underground project, which increased Goldrush’s attributable proven and probable mineral reserves by 3.6 Moz to 4.8 Moz at 7.29g/t. At the Turquoise Ridge complex, attributable proven and probable reserves increased by 1.4 Moz before depletion, principally off the back of a revised geological model at Turquoise Ridge Underground.

Strong results from Africa

In Africa, Bulyanhulu completed an updated underground feasibility study on the Deep West portion of the orebody, allowing us to increase attributable proven and probable reserves by 0.77 Moz before depletion through the conversion of inferred mineral resources. Staying in Tanzania, a fully optimized integrated mine plan at North Mara has increased attributable proven and probable reserves by 1.1 Moz before depletion. Barrick’s two Tier One mines in Africa also delivered strong results, with Kibali able to more than replace depletion of reserves and Loulo-Gounkoto replenishing 98% of depletion for the year.

Total attributable group gold resources, excluding the impact of disposition and equity changes mainly related to Lagunas Norte and Porgera, grew net of depletion, resulting in a 126% replacement of depletion. Mineral resources are reported inclusive of reserves and at a gold price of $1,500/oz. Attributable measured and indicated gold resources for 2021 stood at 160 Moz at 1.50g/t, with a further 42 Moz at 1.3g/t of inferred resources.

The significant increase in attributable mineral resources was led by the Carlin complex in Nevada where a total of 0.91 Moz of measured and indicated resources and 3 Moz ounces of inferred resources were added year-on-year. This was driven by two maiden inferred resource additions, with North Leeville delivering 0.43 Moz at 11.5g/t and Ren contributing 0.76 Moz at 7.3g/t on an attributable basis. Both projects represent future growth for the Carlin complex and drilling continues on both targets, with mineralisation open in all directions.

The remaining year-on-year growth in attributable mineral resources at the Carlin complex mainly came from the open-pits at Gold Quarry and South Arturo as well as the underground at Leeville and Rita K. Staying in Nevada, the Turquoise Ridge complex also increased year-over-year attributable measured and indicated resources by 1.5 Moz mainly off the back of a revised geological model at Turquoise Ridge Underground.

Copper mineral reserves for 2021 are estimated using a copper price of $2.75 per pound and mineral resources are estimated at $3.50 per pound, both unchanged from 2020.

Attributable proven and probable copper reserves were 12 billion pounds at an average grade of 0.38% in 2021. Attributable measured and indicated copper resources were 24 billion pounds at an average grade of 0.35%, and inferred copper resources were 2.1 billion pounds at an average grade of 0.2% in 2021. Mineral resources are reported inclusive of reserves.

Mineral resource management executive Rodney Quick said, “The geological improvements and remodelling are now starting to make a real impact. The incorporation and integration of mine design optimisations are also driving many of the mineral resource additions. A sound understanding of the geological orebody has been integrated with a better understanding of local variations in the geotechnical and metallurgical disciplines to produce integrated and optimized mine designs.”

Energy-intensive aluminium smelter goes fully renewable

0

South32 and partner Alcoa Corporation will restart their Brazil-based Alumar aluminium smelter (Brazil Aluminium), which will be powered 100% by renewable energy, placing it in the second quartile of the global aluminium site cost curve.

First production is expected in the June 2022 quarter, with full capacity from the smelter’s three potlines of 447 000 tpa (100%) to be achieved in the March 2023 quarter. Once at full capacity South32’s wide annualised equity share of aluminium production is expected to lift by 16% (or 179 000 t) to 1 269 000 t.

With the smelter’s energy requirements secured under long term contracts, the alumina supply will be sourced from the co-located Brazil Alumina refinery (36% South32 share), offering substantial efficiencies.

Brazil Aluminium has been on care and maintenance since 2015. South32 expects to invest ~US$70 million (40% South32 share) across FY22 and FY23 to support the smelter’s restart, including ~US$10 million in capital expenditure.

“We are excited to participate in the restart of the Alumar smelter using 100% renewable power. With the smelter benefitting from existing infrastructure, access to our own supply of alumina and long-term green energy sources, we expect our investment to deliver strong returns through the cycle,” says South32 CEO Graham Kerr.

“We see strong long-term market fundamentals for aluminium. By investing along our existing alumina-aluminium value chain with the smelter’s restart and the expected increase to our shareholding in Mozal Aluminium, we are further integrating our business and meaningfully increasing our share of metal produced utilising green energy.

“With this decision we continue to make substantial progress in reshaping our portfolio, increasing our exposure to the base metals required for the critical transition to a low carbon future.”
