MONTRÉAL, QUÉBEC--(Marketwire - April 13, 2011) -BOWMORE Exploration Ltd. (TSX VENTURE:BOW) ("Bowmore") is pleased to announce that it has made it's anniversary payment to Amex Exploration Inc.(AMX: TSX-V, "Amex") for the optioning of the Chivas property covering an area of 24,841 hectares, located in the productive Sierra Madre gold belt of Mexico, State of Sonora. Pursuant to the Option Agreement dated April 8th, 2010 (see press release dated April 8th, 2010) whereas Bowmore can earn up to a 70% interest in the Chivas property, Bowmore was required to make its first anniversary payment in the amount of $100,000 and issue an additional 50,000 common shares of the company to Amex.
During the 2010 exploration program, the Company conducted an airborne survey that lead to the identification of 14 targets, three of which still remain to be investigated and the discovery of two wide silicified zones (lithocap) see press release dated September 24th, 2010. This area of intensely silicified/brecciated stratabound lithocap is situated WSW of the historical Piedra Rodante zone, and is mapped over a strike length of 2.5 kilometres, and possibly up to 125 meters thick, remaining open towards the NNW and SSE. Argillic alteration is also present at its base and southern limit.
The field mapping in 2010-2011 also identified a large area approximately 1.2 km wide by 1.4 km long south of the historical Piedra Rodante target area; this area is known as Mesa Blanca. Mesa Blanca is believed to be the southern extension of the Piedra Rodande hydrothermal breccia which was previously drilled tested (2006-2007) and returned various Au and Ag mineralized intercepts the best being 1.26 g/t Au and 182 g/t Ag over 15.24 meters from hole PR-07-19. At Mesa Blanca local patchy weak to strong silica alteration is common. The silica alteration is indicated by the presence of hydrothermal breccias, micro-breccias and quartz stringers which are hosted by NNW oriented and WSW shallow dipping rhyodacitic flows and tuffs. The quartz is micro-crystalline (chalcedonic) which is an indicator of hydrothermal fluids.
Heavy mineral samples collected at the bottom of the slope within a kilometre of the silicified zone returned anomalous gold values and analyses of several rock samples (grab & chip) revealed anomalous results in arsenic, mercury and antimony associated with the alteration zones.
To summarize, both new discovered areas are interpreted as of a low sulphidation epithermal (Au/Ag) system. In the case of the Silica Cap zone, the observed alteration represents the top level of a mineralizing system whereas the Mesa Blanca zone sinter paleosurface would have been eroded. Though this zone is thought to be at a lower level than the Silica Cap it is still believed to be above the main feeder zone. These three zones (Silica Cap, Mesa Blanca and the Piedra Rodante) covering an area of approximately 3,5 km2 could represent a major epithermal system.
Present work
Presently both areas the "Silica Cap" and the historic "Piedra Rodante" area are being sampled at a 100 meter spacing grid with the objective to collect over 500 samples to conduct a TerraSpec alteration study(visit: www.bowmorexploration.com\chivas.jpg). In addition, surface reconnaissance mapping and sampling over a large Aster colour anomaly situated NNW of the "Silica Cap" was initiated. The exploration field work is concentrated in these areas to get a better understanding in order to define future drill targets.
Mr. Dumas commented "we are very pleased and encouraged with the results obtained to date and the discovery of the silica cap. The actual size of the discovery zone presents a great potential for us as several major deposits within Mexico have very strong geological similarities. The possibility that this zone may extend NNW for an additional 1km to 1.5km provides us with additional targets within the property."
