VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 5, 2014) - Tarsis Resources Ltd. (TSX VENTURE:TCC) ("Tarsis" and "the Company") is pleased to announce that it has carried out further exploration at its Yago project, including sawn channel sampling of outcrop, mapping and rock and soil sampling. The Yago project features gold and silver mineralization within a low-sulphidation epithermal environment.
Sawn Channel Sampling
Sawn channel sampling was carried out within the northeastern part of the La Tejona trend at a target area referred to as the Caliente Zone (previously known as Creek Zone). Detailed mapping re-interpreted the Caliente Zone as an east-northeast striking zone of intense silicification accompanied by multiple generations of crustiform and coliform banded quartz veining in addition to polyphase brecciation. Dominant planar fabrics defining the zone dip moderately to the northwest while a strongly pervasive northerly trending fracture set cuts across the zone and this contains minor crustiform banded quartz veins, veinlets and dry fractures.
Sampling at the Caliente Zone consisted of 8.9 m of exposure within an interpreted 12 m total true thickness. The average grade of the 8.9 m of sawn channel sampling is 4.12 g/t gold and 32.8 g/t silver. Approximately 3.0 m of the zone is covered by slough and vegetation within a narrow localized drainage and this portion of the zone was not sampled.
Channel locations were chosen to optimize cuts perpendicular to the main banding orientation. Thirteen cuts were located at differing elevations along a 60 m section of the zone. Cuts across individual bands and sections of silicification within the zone were projected to a central section and cumulatively interpreted to represent a continuous sample series across the Caliente Zone with the exception of the 3.0 m gap near the hangingwall contact.
Assay results include 3.00 m grading 11.10 g/t gold and 31.6 g/t silver, which in turn includes 1.35 m grading 22.34 g/t gold and 36.5 g/t silver. Detailed assays from the sawn channel sampling are shown in the table below:
- Widths are interpreted to be true width
- bdl - below detection limit
The sample series and results listed in the table are consecutive from the hangingwall contact down through the footwall contact where exposure has permitted access for sawing.
Clearing of vegetation roughly 70 m northeast along the trend of the Caliente Zone revealed abundant vein and silicified breccia material scattered along the surface. Ten samples collected within a 20 m by 20 m area at the northeast end of the trend returned gold values ranging from 0.21 g/t to 6.1 g/t and silver values ranging from 46 g/t to 1,460 g/t. Seven of the ten samples yielded gold values greater 1.00 g/t Au and 150 g/t Ag and the average grade of all ten samples collected was 2.46 g/t Au and 475 g/t Ag.
One excavator trench was located between the new float discovery and the northeastern end of the Caliente Zone outcrop. The trench exposed tan and red weathering andesite within the interpreted hangingwall part of the zone and large angular quartz rubble where the top or hangingwall contact of the zone projected along strike. Bedrock exposure of the vein zone was not possible due to the capabilities of the equipment. Four samples of crustiform and coliform banded quartz plus silicification and breccia were collected from the base of the trench where this material was concentrated along a 3 m section. Gold and silver grades ranged from 0.33 g/t to 2.63 g/t and 55.8 g/t to 537 g/t, respectively.
Tarsis believes the mineralization within the Caliente Zone at this particular location within the 1,600 m long La Tejona Trend is relatively high level but very near the top of the fertile part of the epithermal system. This target is considered a high priority given the thickness of the alteration zone and the tenor of the mineralization at surface.
Photos of the sawn channel samples are available on the Tarsis website (http://www.tarsis.ca/index.php/projects/mexico/yago-mexico#2014-sampling).
Mapping and Sampling
Preliminary mapping and sampling has been carried out along the La Tejona trend, over approximately 1,600 m, primarily focusing on historically documented outcrops with no recorded history of sampling.
Deep pit soil sampling has been conducted at the south-western end of the La Tejona trend in an area referred to as the Florencio Zone.
Additional prospecting was also carried out over select parts of the La Tejona trend and other nearby areas of interest. Results from the mapping and sampling will be provided in a later release.
The company is evaluating the results of this work and planning additional exploration.
The Yago project covers approximately 22,000 hectares, located in Nayarit State, Mexico. The property is accessed by paved road via Federal Highway 15, which crosses the project. The state capital Tepic is located approximately 50 kilometers south of the project.
Sawn samples were approximately 4 cm in width, resulting in relatively large samples per interval, which the Company believes improves the reliability of the sampling. Samples were delivered to ALS Minerals at Guadalajara for sample preparation and all analyses were completed in North Vancouver. Gold values were determined using 30 gram fire assay and other elements were analysed using 51 element ICPMS techniques.
