A first quarter program of six reverse circulation (RC) holes is planned to begin next month (February).
"These six holes will test the down-dip extension of the silver mineralized system beneath cemented alluvial cover and should provide us with an along-strike section across about 200 metres of the silver system's length," said Greg Hahn, the firm's chief executive.
"The fact that the silver mineralization is buried beneath post mineral alluvial cover requires drilling to be able to define the length and width of the system that we see peeking out from beneath alluvial cover at the Ramsey mine workings, and to assess in which direction it is trending."
Road and drill site preparation will begin at the end of January, with permitting of the holes to follow in early February.
The six holes will be sunk immediately east of intercepts from 2016 and 2017, which produced 44.2 metres of 62.5 grams per tonne silver (Ag) in one hole and 53.3 metres of 37.3 g/t silver in another.
Arizona tentatively plans to sink another 9 to 10 holes in the second quarter this year further to the east of these initial six holes.
