Radio Hill (Nickel/Copper/Cobalt):
Artemis has completed an 80-hole RC drilling programme2 at Radio Hill (totalling 7,052 m), designed to delineate the nickel/copper/cobalt mineralisation in the top 70 m of the Radio Hill orebody. Drilling results have arrived from the the lab and results to date are shown in Table 1. Hole locations are shown in Table 2.
The Radio Hill orebody comes to surface near the metallurgical Test Pit area (shown to the right of the RED circle in Figure 1), originally excavated by AGIP in 1985. This Test Pit was originally mined to evaluate the metallurgical characteristics of the Radio Hill Ni/Cu/Co sulphide ores to provide data for the design of the original milling circuit and on-site smelter complex which has been removed.
Partial drill hole results have started to arrive, with the best intercepts (>0.5% Ni) to date highlighted in Table 1. Hole coordinates of these drill holes are shown in Table 2.
Best intercepts received to date include: ? 15m @ 2.05% Ni, 1.94% Cu, 0.09% Co from 27m (ARH066) ? 7m @ 1.9% Ni, 1.07% Cu, 0.08% Co from 18m (ARH015) ? 8m @ 1.14% Ni, 0.96% Cu, 0.06% Co from 75m (ARH007) ? within 17m @ 0.81% Ni, 0.83% Cu, 0.04% Co from 67m (ARH007) ? 3m @ 1.24% Ni, 2.42% Cu, 0.07% Co from 123m (ARH019) ? within 26m @ 0.57% Ni, 0.92% Cu, 0.03% Co from 106m ? 2m @2.93% Ni, 2.90% Cu, 0.12% Co from 19m (ARH020)
All drilling results should be available this month. Artemis is working with AMC Consultants (AMC) to prepare an upgraded Mineral Resource estimate, that can be classified and reported in compliance with the JORC Code (2012). This work is being targeted for completion by the end of April 2018.
Current Mineral Resources at Radio Hill, classified and reported in compliance with the JORC Code (2004) total 4,020,000 tonnes at an average grade of 0.51% Ni and 0.88% Cu (note: no cobalt grades are included in this Mineral Resource).3
Artemis plans to undertake pit optimisation and scheduling following the updated Mineral Resource by the end of April, with a target to commence open pit mining in June 2018.
