Arizona Silver Exploration Inc (CVE:AZS) (OTCMKTS:AZASF) told investors it has moved a core drill rig to its Philadelphia property in Arizona, where it will sink up to four holes.
The holes will test the continuity of the high-grade gold and silver zone on the west side of the Philadelphia vein system which was encountered via drilling announced in November last year.

The company had then reported assays including 41.6 grams per tonne (g/t) gold and 94.4 g/t silver across 0.76 metres (m). Another hole hit a high-grade vein containing 497 g/t (approximately 0.05%) of beryllium, which were the highest beryllium grades reported from the property to date.
In its latest statement, Arizona said it believes there is a "feeder structure on the west end of the vein that accounts for the high gold grades and silver values and high beryllium values encountered there previously".
"The down-dip portion of the vein had very low silver and beryllium values suggesting we were moving away from the feeder structure which we believe to be closer to the west side of the vein," it added.
Meanwhile, at the Ramsey project, also in Arizona, the group said core drilling was suspended due to excessive fragmented rock, and it has decided to return with a reverse circulation (RC) rig, which has demonstrated better efficiency, while getting good recovery and much better productivity.
Returning with a RC rig will save costs and will more efficiently drill this target, said the firm.
