Tom Drivas, CEO, stated, "We have been eager to get a drill back to the Highgrade mineralized area discovered in the Southwest part of Target IV Zone since the discovery was first made at the beginning of 2024. This extraordinary mineralization included 92,758 ppm or 9.28% TREO across 2 meters (See January 16, 2024, news release) and the follow up November 2024 three diamond drill holes with all 3 DD holes intersecting high grade TREO over the entire 3 holes from surface to 150m depts (see January 22,2025 new release). Appia is continuing the drilling program in the Ionic Clay zone with two auger drills; assay results for which will be released once received and analyzed by the Company."
The diamond drill program will include at least 600 meters of drilling in three 200 meter drillholes and is expected to be completed within a +/-25-day timeline (Figure 2). Drilling will continue if holes reach target depth and are still in mineralization.
