MONTREAL, QUEBEC -- (Marketwired) -- 05/07/13 -- Dynacor Gold Mines Inc. ("Dynacor" or "the Company") (TSX: DNG) is pleased to announce the first results of its 2013 exploration drilling campaign, on its 100% owned Tumipampa property. The two-fold exploration program began in December 2012 and includes a drilling program focused on Zone 4 of the skarn and the excavation of a cross-cut (adit) into gold vein structures located south of the skarn. Assay results have been received for the first 6 drill holes, and they reveal high levels of anomalous assays for zinc (Zn), copper (Cu), silver (Ag), gold (Au) and lead (Pb).
All six drilling targets were selected based on geophysics chargeability anomalies (see geophysical survey data in the press release dated September 19, 2011) and coincident surface grab sample anomalies of Au, Ag, Cu and Zn also previously reported (see press releases dated March 7, 2011 and January 27, 2010).
A total of 2,232 meters has been drilled and 510 samples were collected and analyzed from Zone 4 of the skarn. The results discussed below are preliminary and the Company is expecting further assay results on a series of subsequent drill holes including drill holes to the south of Zone 4 as well as two holes that were drilled targeting mineralized vein structures also to the south of Zone 4. Further drilling results will be published when the complete set of assay results have been received and interpreted.
Table 1 below shows the distribution of anomalous values obtained for Au, Ag, Cu, Mo, Pb and Zn using the following cutoff levels to define an anomalous value: Au (0.05 g/t), Ag (0.01 oz/t), Cu (0.005%), Mo (5 ppm), Pb (0.005%) and Zn (0.005%). The anomalous values were found in altered monzonites in proximity to the carbonates (skarns), sheared and mineralized with pyrite, chalcopyrite and sphalerite. The data is consistent with a polymetallic skarn-like deposit.
The high percentage of anomalous values for silver (Ag) 40-86% and zinc (Zn) 30-99% in all the drill holes is very encouraging and requires further investigation. Few anomalous values for gold were observed in the 6 drill holes. Drill hole HDD-03 2012, has an intersection grading 2.24 g/t Au over 1.4 meters between 40.8 m and 42.2 m.
In Table 2 below, the most significant mineralized intercepts obtained from the six drill holes have been summarized.
