RESPEC reported: “The Majuba Hill conceptual block model was evaluated by applying conceptual pit optimizations at various copper prices. Resulting conceptual open-pit scenarios for the mineralized material do not meet the test for “reasonable prospects for eventual economic extraction” with currently appropriate economic inputs. The mineralized volumes of the grade domains and interpolated grades in the block model were considered as well as RESPEC’s understanding of the project mineralization to develop an Exploration Target.
Based on these considerations, a range of between 50 million tonnes and 100 million tonnes has been established for the target. Estimated tonnage and grade ranges of the Exploration Target are shown in the table.
Table:
Model (1) | Million (Tons metric) | ||
Exploration Target - All | 50-100 | 0.15% to 0.30% | 165,000,000 to 660,000,000 |
Exploration Target - High Grade | 10-20 | 0.40% to 0.80% | 88,185,000 to 352,739,000 |
(1)Conceptual open-pit scenarios for the mineralized material do not meet the test for “reasonable prospects for eventual economic extraction” with currently appropriate economic inputs.
Drilling in 2023 on the Exploration Target will concentrate on drilling around the conceptual pits for additional high-grade copper zones using recommendations provided:
Drillhole Locations outside of the clustered drilling that makes up the core of the Exploration Target
Shallower angled drillholes to test and extend the narrow, high-grade zones outlined in the block model.
Orient the 2023 drilling to be more perpendicular to the high-grade zones and the geologic controls for the high-grade zones.

Mineral domains were modeled on cross sections for total copper using three different grade populations. A domain 0 was utilized for material outside the 100, 200, and 300 domains. The cross-sectional mineral domains were sliced horizontally on 10 meter level plans. From this the copper domain polygons were constructed
Domain | Total Copper (%) |
100 | 0.02 – 0.05 |
200 | 0.05 – 0.5 |
300 | >0.5 |
Copper-domain polygons were used to code a three-dimensional block model with a model bearing of 040° comprised of 10 x 10 x 10-meter blocks (model x, y, z). Copper grades were interpolated by inverse distance methods using three-meter composites.
