Arizona Gold & Silver Inc (TSX-V:AZS, OTCQB:AZASF, FRA:A9J0) said on Tuesday it has launched a 27-hole reverse circulation drill program at its Silverton gold-antimony project in Nevada, targeting near-surface antimony mineralization and a deeper concealed gold system. The program will test high-grade antimony-bearing quartz-stibnite veins identified through historical and recent surface sampling at the project, which sits along US Highway 6 between Tonopah and Ely.
