Arizona Silver Exploration (CVE:AZS) (OTMKTS:AZASF) says it is back on track with drilling at its Philadelphia project in Arizona after the first hole of 2020 returned high grade gold and silver.
Diamond drilling last year did hit shallow mineralization 30 metres to the north of a previously identified gold silver zone, with assays including 15.8 grams per ton (g/t) gold and 90 g/t silver over 3.1 metres (m), the firm noted.
And subsequent step-out drilling encountered gold-silver mineralization but did not contain comparable gold and silver values, and importantly contained very low beryllium values.
Thus, a core rig was brought back to the Philadelphia project to see whether the primary vein intersected in earlier drilling had a steeper dip than reflected in the historical workings and that previous company drill holes were terminated prematurely.
"The newest drill results confirm our suspicions that we had lost the primary vein target and were drilling a second but lower grade vein in our previous attempt to chase the primary vein along strike and down dip under alluvial cover," said Greg Hahn, Arizona Silver's vice-president of exploration, in a statement.
"The results of the current drilling put us back on target to chase the primary vein with a steeper dip than previously anticipated."
Results from the latest and first hole included 23.35 g/t gold, 82.3 g/t silver and 340 parts per million (ppm) Beryllium over 1.5 metres, within a thicker interval of 18.45 metres containing 3.81 g/t gold and 49.21 g/t silver and 113 ppm Beryllium.
Hahn added: "The primary vein target remains wide open along strike and down dip. Significantly, we now know that the vein crosses lithology and is not floored by granite everywhere."
Arizona Silver is a mining junior advancing underexplored gold-silver properties in the US state of the same name and Nevada.
