Australia’s Jervois Mining Ltd said on Tuesday its board had approved the final construction and development of its cobalt operations in the US state of Idaho, with the first production expected in mid-2022.
Cobalt is all the rage of late due to its use as a key ingredient in electric vehicles (EVs) and demand for the metal has seen a sharp uptick with rising EV sales and use in batteries.
The approval follows a $100 million bond issue by Jervois on Monday to fund the Idaho project and bring it to production.
Final construction of the project, which the company acquired in 2019, is scheduled to deliver its first ore to an operational mill in July 2022.
The company said it continues to engage with the US government over the “geopolitical and economic importance” of the Idaho facility and further funding support.
Le projet :
https://www.mining-technology.com/proje ... %20More%20The Idaho cobalt project (ICP) is being constructed approximately 40km towards the west of Salmon, Lemhi County, Idaho, US. Located in East Central Idaho in the historic Idaho Cobalt Belt, ICP is the only environmentally permitted primary cobalt project nearing production in the US.
The preliminary economic assessment (PEA) of the ICP was completed in March 2015, while the feasibility study (FS) was completed in September 2017. Commercial production is anticipated to start in the first half of 2020.
The underground mine is expected to produce 31.77 million pounds (Mlb) of cobalt, 42.82Mlb of copper and 39,241oz of gold over its mine life of 12.5 years.

Reserves
The Ram deposit of the ICP is estimated to contain 3.66Mt of proven and probable reserves grading 0.47% cobalt, 0.68% copper, and 0.016oz of gold. It is estimated to contain 34.5Mlb of cobalt, 49.76Mlb of copper and 53,286oz of gold.

Ils indiquent seulement 7 ans de production de façon certaine :
The BFS is based on extracting 2.5M metric tonnes of ore at an average grade of 0.55% Co, 0.80% Cu and 0.64 g/t Au. Initial mine life within the BFS is 7 years, as Jervois sought to maximise initial operating margins, economics and IRR’s. Once underground access has been established and drilling can occur more cost effectively than from surface, unconstrained by seasonality, Jervois has confidence that further resource will be converted to mine reserves (only 60% of the Measured and Indicated Resource has been included in the mining reserve at this time, and none of the Inferred Resource). In addition to known mineralisation, there exists significant potential for additional tonnes along strike and at depth.

Operating costs will be extremely competitive (US$7.45/lb of payable cobalt after by-product credits), with the mine being the first and only United States supplier of ethically sourced cobalt units into the North American market.
