The company has completed 4 boreholes RS-22-01, RS-22-02, RS-22-03 and RS-22-04, total length 800 meters. The initial goal of the fall drilling program was to confirm the original discovery hole GC-12-01, which intercepted 25% of carbon graphite (Cg) over 24 meters.
The original RS-22-01 bore, a twin of the historic GC-12-01, blocks a three-meter-long semi-removable graphite lens. This graphite lens occurs in a pyrrhotite-chalcopyrite-pyrite enrichment interval more than 25 m wide with less graphite in the sulfide.
RS-22-03, an extension of the historic GC-12-01 and RS-22-01 holes, encounters four graphite bands including semi-bulky to large graphite in the latter period.
The RS-22-04, the second step of the historic boreholes GC-12-01 and RS-22-01, traverses a distance of 10.9m semi-mass to bulk graphite from 86 to 96.9m and directly adjacent to the 8.8 meter distance of the sulfide great gap increased from 77.2 to 86 meters, successfully extending the graphite belt identified in the previously published RS-22-03 to the north .
The total known attack length of the Rockstone Graphite Unit is currently around 80 meters and remains open along the attack. Preliminary observations indicate that the giant sulfide layer represents a large sulfide-type mineralization of volcanic origin.
“We are very pleased with the initial results from the fall drilling program at the Rockstone Graphite Project. By seeing the graphite blocks visible in all four holes, we have a better understanding of the graphite structure. and can better identify this potential exploration.The next step in the project,” said CEO Zayn Kalyan. “Following the expected results of the core analysis, the next step in our planning will be to conduct downgrade geophysics and plan to conduct further drilling thereafter. Graphite continues to gain greater acceptance as a status quo. is the key material for the production of lithium-ion battery anodes and we believe supply will continue to tighten, especially given the seasonally lower output in China,” Kalyan added.
In addition to geophysics and further drilling at the Rockstone graphite project, the company hopes to receive results in the coming weeks from a smelting project with SGS Canada in Lakefield, Ontario, which is working to refine coal samples. lead Rockstone into a finished battery of 99.8 %Cg.
The Rockstone Graphite project is located 45 kilometers west of the Port in Thunder Bay, Ontario. The project is well connected by timber roads to paved/gravel roads near the railway and shipping port.
Based on the reprocessed Flexible Time Domain Electromagnetic (VTEM) survey completed by Sabina Silver in 2007, there are 18 drillable EM targets. Drilling at Greencastle in 2012 included four diamond holes (916 metres). The GC-12-01 diamond hole intersecting at a distance of 24 meters contains an average of 0.82% zinc and 0.15% copper in argillaous graphite units. Analysis of 24 m of pulp using the LECO analysis program returned a value of 25% Cg. The rock’s graphite forms appear to be highly ordered hexagonal graphite crystals and crystalline aggregates, likely formed by hydrothermal activity at the formation temperature of 702°C.
