TORONTO, ONTARIO -- (Marketwire) -- 02/19/13 -- Tawsho Mining Inc. (TSX VENTURE: TAW) is pleased to report that a graphite discovery has been made on its Cabot property in Newfoundland. The Cabot Property consists of 102 claims which cover an area of 25.5 sq. km located approximately 12 km north of the village Baie Verte in northwestern Newfoundland. The property, acquired in March 2012 (see press release February 21, 2012), was known to host the Cabot Cu-sulfide prospect and the Marble Cove Au prospect. Although graphitic metasedimentary rock units had been mapped on the property, there is no indication that the area had been explored or actively prospected for economic graphite prospects. Tawsho undertook during the 2012 exploration season to systematically prospect, locate, map and sample graphite occurrences on the Cabot property.
The graphite bearing rock units, however, are rarely exposed on the Cabot property, and where exposed, they are difficult to sample due to their recessive weathering characteristic. The most strongly mineralized intervals occur in the most schistose intervals within the graphitic rock units. Considerable effort was made to take representative chip and grab samples. Given the nature of rock exposure however, the sampling procedures could not be rigidly controlled; the reported assay results in Table 1 only roughly estimate the average concentration of graphite at the sampled location and will have considerable variance.
In the course of extracting the sample from the outcrop, the graphite and host mica schist crumbled readily compared more to the more rigid quartz-feldspar laminae and thin beds. Consequently the sample taken may underestimate the graphite component in the outcrop. The graphite assay results as shown in Table 1 are generally less than the subjective visual field volume percent estimate converted to weight percent of graphite in the rock. Each value estimate however, maintains the same relative value, i.e. higher visual graphite estimates match the higher graphite analytical values. Coarser flake graphite also occurs as small lenticular pods several mm in length and lenticles within and at the margin of quartz and pegmatitic quartz-feldspar veins that cut the graphite bearing rock unit. These veins however, due to their insignificant size and the erratic distribution, were not sampled.
Most of the outcrops sampled were uncovered by removing the soil and/or till cover overlying them. The lateral extent and width of the graphite bearing unit was extended by locating mineralized outcrops on high ground and projecting their host bedding direction across swamps and valleys where mineralized outcrop were eventually located at their projected vicinity.
