Tarsis Resources Ltd. (TSXV:TCC) announced details of its 2011 exploration on the Rogue and recently acquired Plata East prospects, east central Yukon.
As quoted in the press release:
The Company conducted reconnaissance-style exploration that comprised stream sediment and soil geochemical sampling, prospecting and cursory geological mapping on its Rogue prospect and a number of grass-roots targets identified nearby. The targets described represent sediment-hosted silver and/or gold prospects within the Selwyn Basin.
Stream sediment sampling conducted by Tarsis yielded values ranging from 0.1 g/t to 4.3 g/t silver. The stream sediment samples also returned anomalous results for pathfinder elements arsenic (12 ppm to 251 ppm), mercury (0.1 to 1.7 ppm), antimony (0.5 to 148.5 ppm), thallium (0.16 to 1.28 ppm) and zinc (94 to 5,340 ppm).
Soil sampling carried out at one location included the collection of 18 soil samples (across a slope, spaced 25 meters apart) that returned values ranging from 2.7 g/t to 15.9 g/t silver, averaging 7.9 g/t. Mercury values were also strongly elevated (0.1 ppm to 17.1 ppm) while gold values ranged from below detection to 41 ppb.
Plata East Prospect
The Company staked 72 claims to cover the anomalous results.
The claim block is underlain by Mississippian to Permian interbedded calcareous siltstones, shales, cherts and minor dolostones and limestones deposited in a shelf environment unconformably above stratigraphy of the Selwyn Basin.
Sixty-one rock samples representing a number alteration styles were collected during prospecting traverses and assay results returned values ranging from below detection to 0.74 g/t gold. The sample of gossanous float returning elevated gold response also yielded 7.43 g/t silver, 354 ppm arsenic and 2.08 ppm mercury.
