First Quantum Files Updated Technical Report for Ravensthorpe

First Quantum Minerals Ltd. ("First Quantum" or "the Company") (TSX: FM) today filed an updated Technical Report for the Ravensthorpe Nickel Operations ("RNO") in Western Australia. The purpose of this Technical Report is to incorporate updates that reflect the recently completed Mineral Resource and Mineral Reserve estimates and to provide commentary on the status of operations, including recent development work being undertaken to bring the Shoemaker-Levy open pit mine into full production. The effective date for the Mineral Resource and Mineral Reserve estimates is December 31, 2021.

The updated RNO models for Halleys, Hale-Bopp, Shoemaker-Levy, Shoemaker-Levy North and Nindilbillup, incorporate recent drilling and metallurgical test work results. The Shoemaker-Levy deposit makes up 81% of the total RNO Mineral Resource, which remains the main focus for development, extension and mining for the years ahead.

Since the previous Technical Report ("RNO, 2012"), RNO has embarked upon several key upgrades to the processing operations. These include reduced water consumption, cyclone optimization for improved beneficiation as well as limestone ball milling. Additionally, RNO has finalized the required infrastructure for the Shoemaker-Levy mining operations, which includes offices, run-of-mine pads, heavy equipment workshops and laydown areas, power lines and raw water pipelines, and most significantly, crushing facilities and a 9 kilometer overland conveying system.

RNO is strategically positioned as a clean, sustainable source of nickel for electric vehicle batteries with industry-leading environmental credentials and a small carbon emissions footprint. RNO is self-sufficient with respect to power and water and will further reduce its reliance on diesel with the recently constructed overland ore conveying system.


Mining activities commenced at Shoemaker-Levy in 2021. The LOM mining and production schedule highlights a 19-year mine life from January 2022 to the end of 2040. Production in the first five years is expected to be an average of 30,000 tonnes of nickel metal per annum and thereafter an average of 28,000 tonnes per annum. Cobalt production is approximately 1,000 tonnes of metal per annum. The overall LOM strip ratio (tonnes) is expected to be 1.06 to 1.


The updated RNO Mineral Resource estimate (Table 1) has benefited from recently completed drilling, improved quality in the applied density values as well as from results of metallurgical test work. Measured and Indicated Mineral Resources are hosted by the Halleys, Hale-Bopp, and Shoemaker-Levy deposits. The majority of Inferred the Mineral Resource is hosted by the Nindilbillup and Shoemaker-Levy North deposits. The block model estimates were depleted for mining activities completed to date and reported using a 0.3% nickel cut-off grade. Measured and Indicated Mineral Resource estimates increased by 15% when compared to previous ("RNO, 2012") Mineral Resource.

Table 1: Total RNO Mineral Resource statement as of 31st December 2021 (0.3% Ni cut-off). Mineral Resources are inclusive of Mineral Reserves.

Classification Million Tonnes (Mt) Ni (%) Co (%)
Measured 104.64 0.57 0.03
Indicated 120.17 0.55 0.03
Total Measured & Indicated 224.81 0.56 0.03
Inferred 68.26 0.52 0.02


  • The tabled Mineral Resources reflect 100% of the in-situ grades and tonnes.
  • Mineral Resources that are not Mineral Reserves do not have a demonstrated economic viability as per the current reserve criteria.


Mining will occur at Shoemaker-Levy over several phases starting in the south and progressively moving to the north. The Mineral Reserve (Table 2) is based on an average economic cutoff grade of 0.3% Ni, which accounts for a long-term nickel and cobalt price of US$8.00 per pound and US$30.00 per pound, respectively.

Table 2: RNO Mineral Reserve statement as of 31st December 2021.

Classification Million Tonnes (Mt) Ni (%) Co (%)
Proven Reserve 91.40 0.57 0.03
Probable Reserve 86.60 0.56 0.03
Total In Pit Reserve 178.00 0.56 0.03
Total Stockpile 17.70 0.58 0.03


  • The tabled Mineral Reserves reflect 100% of the in-situ reserve grades and tonnes.

RNO's Limonite and Saprolite nickel laterite ore is highly amenable to beneficiation through the rejection of coarse non-mineralised material. The Mineral Reserves average beneficiation uplift in nickel grade is 185% which results in an average nickel leach feed grade of 1.04%.


The Technical Report has been written to comply with the reporting requirements of the Canadian National Instrument 43-101: ‘Standards of Disclosure for Mineral Projects' of the Canadian Securities Administrators, which in turn complies with the Standards on Mineral Resources and Reserves of the Canadian Institute of Mining, Metallurgy and Petroleum (CIM Guidelines, 2019).

Is the World Running Out of Copper? (Updated 2023)

Markets and supply chains across the commodities spectrum have taken hits from factors like the COVID-19 pandemic, inflation and Russia's war in Ukraine. Base metal copper is no exception, and now some analysts are once again calling for peak copper in much the same way as others have voiced concerns over peak oil or peak gold.

After the 2008 recession, copper surprised everyone with its rapid ascent — propelled by China's stockpiling program, it hit record-high prices. In 2011, concerns that peak copper was on the horizon were exacerbated by the rapid industrialization seen in China. As the Asian powerhouse's copper demand skyrocketed, copper stockpiles had a tough time meeting the increased demand.

That raised the question of when the market will reach peak copper, which is a time when global copper supply will enter a terminal decline. The predictions surrounding the timing of peak copper were are all over the map, ranging from 2020 to 2100.

Economics of the Copper Scrap Market (Updated 2023)

Copper is one of the most important materials in our everyday life, and copper scrap material represents a strategic source of this crucial base metal.

Copper is widely used in building construction, electrical grids, electronic products, transportation equipment and home appliances. Rising demand for renewable energy, electric vehicles and high-tech products bodes well for copper, as it has the highest conductivity of any metal apart from silver, making it ideal for the green economy.

Recycled copper scrap contributes significantly to supply, and plays a behind-the-scenes role in balancing the market. "Copper's recycling value is so great that premium-grade scrap normally has at least 95 (percent) of the value of the primary metal from newly mined ore," states a report from the Copper Development Association.
