Black Mountain Resources (ASX: BMZ) has staked a further 20 mining claims covering 167 hectares at its Conjecture Silver Project in Idaho after intersecting high grade silver in its 2012 drilling program.
It has also installed the culvert at the portal entry for the Graham Adit and has started work on the construction of a decline to cross cut and access historic working levels.
With the latest claims, Black Mountain now holds a total of 59 mining claims that form the Conjecture Silver Project.
These cover 283 hectares in a prolific silver region and assure its position for continued exploration and resource expansion at the property.
The new area, along with additional potential resources identified from 2012 drilling, will be evaluated for the 2013 exploration program.
"We are extremely excited about the potential of the Lakeview Mining District, and we are therefore delighted to increase our already significant area of interest," chief executive officer John Ryan said.
"This region has the same geological signature of the prolific Coeur d'Alene Mining District, and both high grade, shallow silver intercepts up to 1,106 grams per tonne received from our recent drilling campaign, and the historic high grade mining, underpin the prospectivity of the region."
On the development front, Black Mountain noted the decline will be driven at a 15 degree decline and parallel to the vein zone to enable further exploration and development of historic workings as well as new ground.
Cross cuts are proposed to be driven from the decline to the vein zones about every 61.2 metres.
Additionally, i-drifting on the veins is planned to enable bulk sample testing of the vein zone as well as delineation of additional potential resource blocks for eventual mining.
"We are delighted to have commenced driving of the decline, a significant step towards this target, and we look forward to updating shareholders regarding our development progress both here, and at our New Departure Silver Project in Montana, over the coming months," Ryan added.
Black Mountain also advised that long awaited initial assay results should be available for New Departure Silver Project drill holes next week.
