Alpha Copper Corp., a resource company established to generate value via mineral exploration and asset advancement, provided a timely report on its recently completed summer diamond drilling program at its Indata copper-gold property.

The property is located within the rocks that cross the Paleozoic Cache Creek Group and the Mesozoic Quesnel Terrane. Indata is situated 240 km northwest of Prince George, 88 km west of the Mount Milligan mines owned by Centerra, and 16 km south of the Kwanika and Stardust projects owned by Northwest Copper.
Midway through September, Indata’s multi-week 2022 summer drill program came to an end. 13 holes totaling 2,140 meters in length were performed, with a focus on targets for porphyry copper, carbonate replacement deposits (CRD), and quartz veins.
In six of the 2022 drill holes, porphyry copper mineralization was found in both the Lake Zone and a new region 500 meters to the south. In chlorite-altered Triassic-Jurassic andesite and diorite, extensive silicification and biotite alteration are related to mineralization.
Previous drill results from the Lake zone include 27 meters averaging 0.27% copper in hole 08-I-01 and 148.2 meters of hole 98-4 averaging 0.2% copper with an interval of 0.37% copper over 24.1 meters. There is currently no restriction on how far the Lake zone can grow.
Furthermore, two distinct locations in the northwest and southeast regions of the property showed potential for CRD-type mineralization during the summer drilling program of 2022. Two of the drill holes—IN22-74 and IN22-84—found porphyry molybdenum.
The northwest hole IN22-84 also came across a large limestone breccia unit that included manganoan calcite, another sign of the adjacent CRD mineralization, and substantially anomalous lead, zinc, arsenic, antimony, (±gold) values in surface samples.
In two of the holes, IN22-77 and 78, mesothermal quartz veins were discovered. These are similar to those in the eastern part of the property, where historical drilling has yielded results of 9.8 g/t gold and 51.4 g/t silver over 1.3 meters in drill hole 87-I-4 and 1.8 g/t gold and 114.1 g/t silver over 2.5 meters in hole 87-I-1.
On the Indata property, located further to the north, historical high-grade gold intercepts include holes 88-I-11 with 46.2 g/t gold and 2.0 g/t silver over 4.0 meters and 89-I-6 with 354.1 g/t silver over 3.2 meters.
Our discovery-focused program continues to advance and unlock increasingly important results. The information we have compiled to-date continue to steer our efforts and bolster our understanding of the underlying mineralization at this exciting property.

Jones added, “Our early analysis drives our strategic planning to move ahead and generate additional increasingly valuable drill targets for our proposed fall drill campaign. Every meter of drilling so far continues to build a progressively clearer picture as to the extent of asset potential at Indata. We look forward to drilling ahead in the pursuit of shareholder value.”
