Arizona Silver Exploration Inc (CVE:AZS) said it was encouraged by latest drill results from the past producing Ramsey silver mine project in La Paz county.
The assays are the second batch of results from the first phase of drilling.
Arizona reckons it has intersected the periphery of a much larger silver-bearing hydrothermal system.
The mineral system appears to be very large and is open to the east and south, where there has been no previous drilling, it said.
Drill hole R1706 hit 145ft with approximate true width of 35 metres containing 62.5 g/t (grams per ton) of silver between a depth of 260 and 405 feet.
Another hole - drill hole R1707 - hit 175 feet with approximate true width from 280 to 455 feet (85.4 to 138.7 metres) containing 37.3 g/t (grams per ton) silver within a wider zone of silver mineralization from 215 to 465 feet.
At another target - the Western deep anomaly, the firm said it had hired a geophysical consultant to model the anomaly
