BOWMORE Commences Duverny Drill Program in the Abitibi

MONTRÉAL, QUÉBEC--(Marketwire - Nov. 29, 2012) - BOWMORE Exploration Ltd. (TSX VENTURE:BOW)(FRANKFURT:0B5) ("Bowmore") is pleased to announce the start of Phase Two 3,000 meter diamond drill program on its Duverny property, located in the Abitibi region of Quebec. The objective of the second phase of drilling will be to test large zones of rusty iron carbonate alteration that host a number of gold showings, all identified through the summer 2012 sampling and geological mapping program. The drill targets include

  1. Two gold showings of 1.35g/t Au over 3.4 meters and 1.76g/t Au over 2.4 meters that were obtained from chip samples taken this summer within historical trenches, located in the central part of the property, a few hundred meters north of the historical Cresus-Silverny gold showing;
  1. a second iron carbonate alteration zone extending ESE of the Claverny gold showing, located on the south eastern part of the claim block, 3.7 kilometers from the Cresus-Silverny showing;
  1. the Grenadier West zone located on the north-east part of the property. Gold values of up to 2.9g/t Au were obtained from grab samples taken within the area during the summer 2012 exploration program.
  1. the Duvay gold showing, located on the northern part of the property, where bulk samples for heap leach testing were taken in the late 80's.

The iron carbonate (ankerite) alteration zones on the Duverny property cover a total of approximately 18 square kilometers. This intense rust-colored carbonate alteration is similar to what surrounds the historical, world-class Larder Lake, Timmins and Red Lake gold camps in Ontario.

The 2012 summer exploration program consisted of geological mapping with 100 meter spacing surface rock sampling in order to define levels and types of mineralization and carbonate alteration. A total of 485 samples (424, 1kg grabs and 61 chip samples) were taken and sent for gold analysis at ALS Chemex, for which some results are still pending. The sixty one (61) chip samples were also analyzed by the same laboratory for multi element package ICP-MS41 while twenty four (24) of the grabs were analyzed for trace elements (CCP-PKG01). Gold content was first analyzed utilizing standard fire assay fusion of a 30 gram (AA23) or a 50 gram (AA24) charge, followed by Atomic Absorption Spectroscopy (Au 30-50g FA AA finish). All other elements, including silver, were analyzed utilizing Inductively Coupled Plasma - Atomic Emission Spectroscopy (35 Element Aqua Regia ICP AES) methods, on a prepared sample digested with aqua regia.

The company is in the process of obtained all necessary agreements and permits for property access and drilling work to be done on the targeted areas.


The property is located 15 kilometres northeast of the town of Amos in the prolific Abitibi region of Quebec. The property has been the object of historical exploration work since the 1920's, including diamond and reverse circulation drilling, and bulk sampling that reported numerous gold occurrences within the property limits and its vicinity. The property is located in a favourable geological setting to host low-grade, bulk tonnage disseminated gold mineralization as well as high-grade, carbonate-rich vein systems. The property geology is dominated by volcanic rocks and covers the edges of the Duverny and Claverny felsic igneous plutons. The property encompasses very large, kilometric zones of intense iron carbonate alteration (ankerite) and a network of significant shear zones in proximity to the felsic intrusions.

Mr. Paul Dumas, President and CEO of Bowmore Exploration Ltd., stated: "I am pleased to see the Phase Two drill program at our Duverny property underway prior to the year end. The property presents a great potential for significant gold mineralization. Some of the historical diamond drill holes indicate good grades and we are hoping to expand these areas of interest."
