Tarsis discovers sediment-hosted gold system at Erika

 Tarsis Resources (CVE:TCC) said Thursday that it has discovered a sediment-hosted gold system at its Erika property in Mexico.

Drilling at Erika initially targeted epithermal style mineralization, within holes ER-11-01 to ER-11-08, intersecting trace levels of gold, ranging from below detection to 55 parts per billion (ppb), but with significant values for arsenic of up to 6,080 ppm.

However, upon inspecting historical drill core from hole EK-03, the company decided to drill another five holes to establish vectoring data within this particular part of the mineralizing system, generating targets.

Drilling has encountered mineralization in four of five holes drilled across a 650 metre transect, the company said. This package of rocks is contained within a broad north-northeasterly trending structural corridor.

Assays have so far been received for three holes, with historical hole EK-03 intersecting 2.13 metres, grading 0.87 grams per tonne (g/t) of gold. Holes ER-11-09 returned 0.92 metres of 0.58 g/t gold, and hole ER-11-10 intersected 0.50 metres at 0.94 g/t gold.

Tarsis said that while the weighted average grades of the mineralized zones are sub-gram gold, a number of key features exist, including anomalous thallium, mercury, arsenic and antimony, "exhibiting excellent correlation with gold mineralization".

Further analysis of the quartered core from EK-03 shows the mineralized interval has significant increased silica and coincident depleted calcium content, the company said.

"Exploration for sediment-hosted gold is at an early stage at the Erika project and the company is highly encouraged by the lateral extent of the gold mineralization and the consistent alteration style and association with key pathfinder elements," said president Marc Blythe.

"Much needed vectoring analysis is now required to identify source proximal targets in this largely blind-to-surface mineralizing system."

Tarsis plans to pause drilling activity now for more analysis, with additional drilling to continue after the rainy season. In the meantime, the company has commissioned a high-resolution ground magnetic survey within the corridor of interest, due to be completed this month, with results expected to identify potential feeder zones.

In addition, the company has received results from a soil sampling program at Erika, with two distinct gold-in-soil anomalies having been outlined within the Souwest grid, south of the current drill transect.

Both anomalies are defined by intermittent clusters of gold-in-soil values 20 ppb and greater, and up to a maximum of 92 ppb.  The larger of the two anomalies measures approximately 1100 by 500 metres.  The anomalies are 600 metres apart, and both contain coincidentally-elevated arsenic, thallium, mercury and antimony.
