(TheNewswire)
Cremorne, AU -TheNewswire - February 8, 2023 - Jervois GlobalLimited (“ Jervois ” or the “ Company ”) (ASX:JRV)(TSX-V:JRV) (OTC:JRVMF) has received all resultsfrom an in-fill drilling program at its Idaho Cobalt Operations(“ ICO ”) in Idaho, United States (“ U.S. ”), which haveconfirmed grade continuity and widths consistent with the MineralReserve and Resource Estimate (“ MRRE ”) at the RAMdeposit.
Highlights:
-
2022 in-fill drilling at Jervois’100%-owned Idaho Cobalt Operations (“ICO”) improves confidence inthe Mineral Reserve and Resource Estimate (“MRRE”) and furtherde-risks mining
-
Results now received from all 62in-fill holes completed in 2022, which together with expansiondrilling will be incorporated into an updated MRRE for ICO, expectedQ2 2023
-
Results indicate continuity andconsistency with existing RAM resource drilling and correspond wellwith grades and widths predicted by the existing RAM resource model
-
Geotechnical data gained from in-filldrilling adds to the existing database and increases confidence inground conditions
-
In-fill drilling will continuethrough 2023 as ICO vertical mine development progresses
-
ICO is the only cobalt mine in theU.S., which Jervois expects to ramp up to nameplate capacity across Q22023
Jervois’ 2022 in-fill drilling program at ICOtotalled 7,730 metres (“ m ”) in 62 completed diamond drillholes,focused on the RAM deposit underpinning current mine development atICO, along with a single geotechnical drillhole. All 62 in-fillholes targeted and intersected the Main Mineralised Horizon(“ MMH ”) of the RAM deposit.
As previously disclosed, in-fill drilling has confirmedthe current RAM deposit MRRE model and continues to de-risk mining,with drillhole spacing reducing from 50m down to 20m in near termproduction fronts.
In-fill drilling is ongoing and will continue through2023 as vertical mine development progresses, focused on productionareas within the upper levels of the South Zone and lower levels ofthe Mid Zone of the deposit.

Quality Assurance
All drill core samples are sent to ALS GlobalLaboratories (Geochemistry Division), an independent and fullyaccredited laboratory (ISO 9001:2008), in Vancouver, Canada, foranalysis for gold by Fire Assay and multi-element Induction CoupledPlasma Spectroscopy. Jervois employs a regimented Quality Assurance,Quality Control (“ QA/QC ”) program where at least 10%duplicates, blanks and certified reference material are inserted intoeach sample shipment.
