Corcel Exploration has released final assay results from its Phase I drill program at the Yuma King Project in west-central Arizona, completing 1,087 metres across six drill holes with copper and gold intersected in every hole.

Drill hole YK26-006 returned two distinct mineralized zones separated by a porphyritic intrusion. The lower sulfide zone yielded 24.5 metres of 0.47% copper, 0.32 g/t gold, 3.59 g/t silver, and 164 ppm molybdenum from 212 metres downhole, including 10.14 metres grading 0.65% copper, 0.47 g/t gold, 4.73 g/t silver, and 141 ppm molybdenum from 219.21 metres. The upper oxide zone returned 4.4 metres of 0.71% copper, 0.19 g/t gold, 8.46 g/t silver, and 5.5 ppm molybdenum from 28.05 metres.

Meanwhile, drill hole YK26-005A intersected 8.97 metres of 0.46% copper, 0.39 g/t gold, 3.8 g/t silver, and 250 ppm molybdenum starting at 116 metres downhole, adjacent to a porphyry intrusion containing 47 metres of strongly anomalous copper, gold, and molybdenum. The deeper mineralized skarn intersection in YK26-006 suggests the skarn horizon is structurally duplicated or present in multiple horizons.

The project spans a district-scale land position of 3,200 hectares comprising 515 unpatented federal mining claims in the Ellsworth Mining District and hosts the past-producing Yuma King Mine, which recorded underground production of copper, lead, gold, and silver between 1940 and 1963.

“Phase I has significantly advanced our understanding of Yuma King and highlighted the potential for a much larger copper-gold system,” commented Jon Ward, CEO of Corcel Exploration. “We have demonstrated continuity of copper-gold skarn mineralization, intersected additional mineralized skarn at depth, and encountered strongly anomalous copper, gold and molybdenum within the associated porphyritic intrusions. Together, these results expand the prospective skarn footprint and provide compelling vectors toward a potentially concealed porphyry system.”

Following the completion of the Phase I program, Corcel plans to advance and test several compelling targets during a Phase II exploration program.
