Jervois’ in-fill Drilling at ICO Adds Confidence in RAM Resource

Cremorne, AU – TheNewswire – February 8, 2023 – Jervois Global Limited (“Jervois” or the “Company”) (ASX:JRV) (TSX-V:JRV) (OTC:JRVMF) has received all results from an in-fill drilling program at its Idaho Cobalt Operations (“ICO”) in Idaho, United States (“U.S.”), which have confirmed grade continuity and widths consistent with the Mineral Reserve and Resource Estimate (“MRRE”) at the RAM deposit.

Highlights:

2022 in-fill drilling at Jervois’ 100%-owned Idaho Cobalt Operations (“ICO”) improves confidence in the Mineral Reserve and Resource Estimate (“MRRE”) and further de-risks mining
Results now received from all 62 in-fill holes completed in 2022, which together with expansion drilling will be incorporated into an updated MRRE for ICO, expected Q2 2023
Results indicate continuity and consistency with existing RAM resource drilling and correspond well with grades and widths predicted by the existing RAM resource model
Geotechnical data gained from in-fill drilling adds to the existing database and increases confidence in ground conditions
In-fill drilling will continue through 2023 as ICO vertical mine development progresses
ICO is the only cobalt mine in the U.S., which Jervois expects to ramp up to nameplate capacity across Q2 2023

Jervois’ 2022 in-fill drilling program at ICO totalled 7,730 metres (“m”) in 62 completed diamond drillholes, focused on the RAM deposit underpinning current mine development at ICO, along with a single geotechnical drillhole. All 62 in-fill holes targeted and intersected the Main Mineralised Horizon (“MMH”) of the RAM deposit.

As previously disclosed, in-fill drilling has confirmed the current RAM deposit MRRE model and continues to de-risk mining, with drillhole spacing reducing from 50m down to 20m in near term production fronts.

In-fill drilling is ongoing and will continue through 2023 as vertical mine development progresses, focused on production areas within the upper levels of the South Zone and lower levels of the Mid Zone of the deposit.

Quality Assurance

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