Majuba Hill Copper Corp.: Outlines Exploration Target of 50 to 100 million tonnes at Majuba Porphyry in Nevada
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: Exploration Target Size Range from Conceptual Block Model
Model (1) | Tonnage Range Million (Tons metric) | Grade Range Copper (%) | Copper Range (pounds) |
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 |

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.
David Greenway, CEO stated, "I am excited that we have been able to get Majuba Hill to this critical point in the development of a copper deposit in just three years. Having such a significant Exploration Target with the potential of 10 million tonnes and 20 million tonnes of material grading between 0.40 % Cu and 0.80% copper grades is tremendous for the future of the company. This puts the Majuba Hill Copper Corp. in a rare position for a company of our size. We now know we have conceptual pits that can be advanced towards development. The 2023 Target Corridor outlines what we believe will ultimately contain over 1 billion tons of copper mineralization.
Mineral Domains and Block Modeling

Copper Domains, and Block Model

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.

About Majuba Hill Copper Corp.
Majuba Hill Copper Corp. is engaged in the identification, review and acquisition of latter stage copper and copper/silver/gold assets. This is in direct response to the growing worldwide demand and lack of supply for precious metals fueled by the Green New Deal in the US and most other developed nations with similar programs aimed at addressing climate change. Such programs are heavily reliant on silver, gold and especially copper to produce Electric Vehicles and other renewable power sources, as well as building infrastructure to provide clean and affordable electricity.
The flagship project is the Majuba Hill copper, silver and gold District located 156 miles outside Reno, Nevada, USA. Management has been mandated to focus on safe, mining friendly jurisdictions where government regulations are supportive of mining operations.
