Black Pine Project, Lemhi County, Idaho USA
The Black Pine Property is located approximately 17 miles from the town of Salmon, Idaho, in Lemhi County, proximal to Jervois ( the Company)’s Idaho Cobalt Project (ICP). Stratiform sulphide mineralization is found in massive sections which typically contain pyrite and chalcopyrite. Aside from the copper rich strata, there are a number of narrower cobalt-gold rich arsenopyrite-bearing beds present in the copper mineralized section. Primary cobalt mineralization within the Regina target has returned some broader cobalt intervals as well as multiple stacked narrower beds. The narrower strata typically carry values sufficiently high to be minable when diluted to a 6 foot mining width. Due to its proximity to the Idaho Cobalt Project, the Black Pine deposit is considered a potential source of future feed material for the ICP mill.
Mineralization was first discovered in the area of the present Black Pine property in the late 1800s with several short adits, crosscuts and a shaft completed by 1947. By the 1960’s, operators had estimated a historical mineable reserve in one of twelve defined target zones of 340,000 tons grading 3.5% copper (Shockey, P.E. and Calaghan, E.E (1962), referenced in Roscoe Postle Associates Inc. “Report on the Blackpine and Sunshine Properties, Lemhi County, Idaho for Formation Capital Corporation”, dated May 05, 1995 – Note: these resources although relevant are historical in nature and are not NI 43-101 compliant and therefore should not be relied upon. The 1962 resource categories do not use current NI 43-101 resource categories and the company has not done sufficient work to convert the resources to current mineral resource categories. Additional work will be required to verify their presence and economic viability. The Company is not treating these resources as current.
In 1992, Jervois optioned the Black Pine property and shortly thereafter staked additional claims. Since the acquisition of Black Pine, we have invested CAN$3.2 million on property payments and exploration including geological mapping, soil geochemistry, geophysical surveys, trenching and drilling programs. 100 diamond drill holes totaling 44,954 feet, and 100 reverse circulation holes totaling 15,625 feet were completed in the late 1990’s.
Management has since concentrated its development efforts on its nearby Idaho Cobalt Project, but the Blackpine project remains an attractive copper, cobalt and gold property with historic resources that require additional exploration to evaluate its full mineral potential.
Virgin River & Centennial Zone, Athabasca Basin, Northern Saskatchewan, Canada
During the year ended February 28, 1999, the Company’s wholly owned subisidiary, Coronation Mines entered into a joint exploration agreement with UEM Inc. whereby Coronation aquired 2% of the Virgin River project with the first right of offer to acquire up to 10% and a carry through to $10 million worth of exploration and development. UEM Inc. was a corporation owned 50% by Cameco Corporation (“Cameco”) and 50% by AREVA. Subsequently, UEM was dissolved and both Cameco and AREVA became equal partners (49% each) in the joint exploration agreement. Cameco is the operator of the project. As of February 28, 2016 over $33.9 million has been spent on the project exploring a large unconformity-type deposit that has resulted in the discovery of the Centennial Deposit.
The Centennial Deposit has been traced over 650 meters of strike length and has a minimum across strike width ranging from 10.0 meters to 52.5 meters. Approximately $11.9 million was reported by Cameco as having been spent on the 2009 – 2011 drill programs that were designed to follow up on the 2004 – 2008 drill results from the Centennial Zone.
High grade U3O8 intersections of up to 298 GT have been intersected within the Centennial Deposit (33.9 meters grading 8.78% U3O8 — see Company News release dated May 30, 2011). GT is defined as % grade U3O8 multiplied by thickness in meters. Assay results returned from diamond drill programs from 2004 to 2011 on the Centennial deposit have resulted in 39 significant primary uranium intersections returning results greater than 10.0 GT.
A total of 7,746.2 meters were drilled in 6 pilot diamond drill holes and 7 wedge off-cuts during the 2011 diamond drill program on the Virgin River project. Results of this program were discussed in the Company’s news release dated January 12, 2012 with final results of the program released subsequent to fiscal year end in a news release dated April 4, 2012.
All drill holes completed on or immediately surrounding the Centennial Deposit in 2011 displayed uranium enrichment throughout the basal sandstone in contact with the basement unconformity with elevated pathfinder elements such as lead, vanadium and nickel. Significant high grade uranium intercepts were intersected in 7 of the drill holes with GT’s over 10.
Note: Inductively Coupled Plasma – Optical Emission Spectroscopy Split assay results with core recovery intervals of less than 75% were replaced by shielded probe results.
All uranium assays were carried out by the Saskatchewan Research Council of Saskatoon, Saskatchewan. Delayed neutron counting and / or X-ray fluorescence spectroscopy U3O8 check assays were completed on all split assay samples returning greater than 1.0% U3O8. The average of the check assays and the Inductively Coupled Plasma – Optical Emission Spectroscopy results were used in the calculations of grade thicknesses.
The exploration program for 2019 included 6 diamond drillholes for 5,574m. Further exploration is planned in 2020.
Kernahan/Bell Project, Athabasca Basin, Northern Saskatchewan, Canada
Jervois’s wholly owned subsidiary, Coronation Mines Ltd., granted an option whereby Cameco (40%), and AREVA (40%) have earned 80% interest in certain mineral claims by making payments and completing $1,000,000 in exploration work. AREVA is the acting operator. The project area is located near the northeast rim of the Athabasca Basin approximately 42 km north of Points North Landing. The Kernaghan / Bell project currently consists of 13 mineral claims totaling 4,342 ha. To date 38 diamond drill holes have been completed within the property totaling 10,051m targeting an unconformity that ranges from 160m to 290m in depth.
Eight diamond drill holes totaling 2,683.4m were completed during 2009 exploration, budgeted at $820,000. Four holes were drilled on the KER A conductive trend with the remaining four holes having been drilled on the K1 conductive trend. Although anomalous uranium intersections with a maximum partial uranium value were returned from Ker A Conductor in drill hole KB-11 of 160 ppm and a maximum partial uranium value returned from K 1 Conductor in drill hole KB-07 of 34.2 ppm, none of the holes drilled in 2009 intersected significant uranium mineralization.
There was no proposed budget for field work for the current period.
Silverside Project (100%)
Silverside, acquired during the merger with M2 Cobalt in 2019, is located approximately 450km north of Toronto, Canada and is approximately 30km northwest of the town of Cobalt. The project consists of four mineral claims which have had limited exploration conducted on them in the past. They are however prospective for Cu-Co mineralisation in narrow structures.
Arunta West Project (49%)
The Arunta West project consists of three exploration licences covering 345 sq km about 600km west-northwest of Alice Springs in the Gibson Desert near the WA/NT border. Jervois entered a joint venture agreement with Australian Mines Limited (ASX: AUZ) on the Arunta West Project in 2016, AUZ subsequently spun-out the joint venture to Norwest Minerals Ltd which is the operator and manager of the project.
Jervois completed its planned drill programme at its Kilembe area properties in central and western Uganda, and following receipt of assays from Q4 2020 exploration, announced the results on 27 January 2021.
Drilling at the Kilembe area properties targeted surficial Au-Cu mineralisation detected through earlier geochemical programmes. In total, 1,905 metres of diamond drilling was completed in 17 holes drilled at the Kilembe area properties in 2019 and 10 holes in 2020, totalling 1,409m.
All exploration activities in Uganda have been suspended due to a combination of ongoing COVID-19 risks, political and regulatory developments in-country and results to date at Bujagali which do not meet mineralisation model expectations for copper-cobalt ore deposits. Jervois is initiating a partnering process for its Ugandan exploration portfolio and in particular its Kilembe area properties.
