Dynacor Extends a Drift and Excavates Two Raises in the Southwestern Zone of the Manto Dorado at Tumipampa
MONTREAL, QUEBEC--(Marketwired - Apr 12, 2016) - Dynacor Gold Mines Inc. (TSX:DNG)(OTC:DNGDF) (Dynacor or the Corporation) is pleased to announce continued positive underground exploration results on the southwestern zone of the highly mineralized Manto Dorado structure at Tumipampa (Peru).
Exploration Highlights
- Excavation of a 30-meter long raise (Raise 105, see Figure 1) from the 8-meter mark in Drift 190SW to follow the vertical extension of the gold, silver and copper mineralisation in the Manto Dorado. Channel sampling in the first 14-meter segment found an average grade of 8.38 g/t Au, 1.84 oz/t Ag and 1.18 % Cu over a true width (TW) of 1.34 m;
- High grade channel samples from Raise 105 include: samples #10632 grading 72.24 g/t Au, 13.73 oz/t Ag and 4.99% Cu over a true width of 1.5 m and #10630 grading 21.17 g/t Au, 2.02 oz/t Ag and 2.24% Cu over a true width of 1.8 m;
- Extension of Drift 190NW in the Manto Nelly by 63 meters to the northwest in order to follow the mineralization in this recently discovered structure (see Table 1 below and press release dated 15 October 2015);
- Excavation of a 34-meter long raise (Raise 090, see Figure 1) to follow the vertical extension of the gold, silver and copper mineralisation in the Manto Nelly. Channel sampling in the first 12-meter segment found an average grade of 2.98 g/t Au, 0.88 oz/t Ag and 0.32% Cu over an average true width of 1.60 m; and
- High grade channel samples from Raise 090 include: samples #10561 grading 6.70 g/t Au, 0.88 oz/t Ag and 0.67% Cu over a true width of 1.4 m and #10559 grading 5.90 g/t Au, 0.65 oz/t Ag and 0.45% Cu over a true width of 1.5 m.
Results
Manto Dorado
Background: At the 170-meter mark along cross-cut 330NW a 125-meter long by-pass gallery was excavated in order to reach the rich mineralization found in the southwestern extension of the Manto Dorado and intercepted by drill hole HDD-07-15. This 226.70-meter long hole first intercepted a split of the Manto Dorado structure at 143.4 m grading 3.99 g/t Au over a true width of 2.70 m including an assay of 8.58 g/t Au, 0.22 oz/t Ag and 0.34% Cu over a TW 0.61 m. This drill hole then intercepted at 155.0 m mark the Manto Dorado structure with grades of 10.21 g/t Au, 3.02 oz/t Ag, 0.96% Cu over a true width of 3.69 m including an assay of 42.14 g/t Au (uncut assay), 13.63 oz/t Ag, 3.70% Cu over a true width of 0.74 m (see Figure 1).
At the end of the by-pass a 19-meter long drift (Drift 190SW) was excavated into the Manto Dorado and 15 channel samples returned an average grade of 8.50 g/t Au, 1.95 oz/t Ag and 0.80% Cu over an average true width of 1.35 m including a channel sample assay of 23.46 g/t Au, 1.25 oz/t Ag and 1.70% Cu over a true width of 0.70 m (see Press Release dated October 15, 2015).
Raise 105 - Manto Dorado
From the 8-meter mark along Drift 190SW, a 30-meter long raise was excavated to follow the vertical extension of the gold, silver and copper mineralisation in the Manto Dorado. Thirty channel samples were taken in Raise 105 and analysed.
Channel sampling in the first 14-meter segment of Raise 105 found the following average grades: 8.38 g/t Au, 1.84 oz/t Ag and 1.18 % Cu over an average true width of 1.34 m. High grade channel samples included: samples #10632 grading 72.24 g/t Au, 13.73 oz/t Ag and 4.99% Cu over a true width of 1.5 m and #10630 grading 21.17 g/t Au (uncut assay), 2.02 oz/t Ag and 2.24% Cu over a true width of 1.8 m. Channel sampling in the second 16-meter segment of Raise 105 returned an average grade of 0.99 g/t Au, 0.37 oz/t Ag and 0.07% Cu over an average true width of 0.98 meters. The results are given in Table 1 and Figure 1.
Manto Nelly
Background: At the very end of Drift 190SW a new mineralized structure was discovered, the Manto Nelly orientated at N49°W. An 18-meter long drift (Drift 190NW) was excavated along the Manto Nelly and channel sampling returned an average grade of 4.80 g/t Au, 1.46 oz/t Ag and 0.80% Cu over an average true width of 1.50 m (see Press Release dated October 15, 2015).
Extension of Drift 190NW
In order to further follow the mineralization of the Manto Nelly, Drift 190NW was extended a further 63 meters following the Manto structure orientated N60°W and dipping 28°NE. The mineralization is associated with a brecciated quartz structure with sericite, including with disseminated pyrite and with irregular lenses of hydrothermal breccia and bands of carbonate, sphalerite and galena.
Channel samples were taken every 2 meters along the 63-meter extension and subdivided into two segments. The first 21-meter segment has an average of 1.99 g/t Au, 1.48 oz/t Ag and 0.62% Cu with an average true width of 1.21 m; and the second 42-meter segment has an average grade of 0.97 g/t Au, 0.32 oz/t Ag and 0.12 % Cu with an average true width of 1.14 m. (see Table 1)
Raise 090 - Manto Nelly
A 34-meter long raise (Raise 090, see Figure 1) was excavated to follow the vertical extension of the gold, silver and copper mineralisation in the Manto Nelly.
Channel sampling in the first 12-meter segment of Raise 090 returned an average grade of 2.98 g/t Au, 0.88 oz/t Ag and 0.32 % Cu over an average true width of 1.60 m. Eleven channel samples were collected and analysed. High grade channel assays include samples: #10561 grading 6.70 g/t Au, 0.88 oz/t Ag and 0.67% Cu over a true width of 1.4 m and #10559 grading 5.90 g/t Au, 0.65 oz/t Ag and 0.45% Cu over a true width of 1.5 m. Channel sampling in the second 22-meter segment of Raise 090 returned an average grade of 1.22 g/t Au, 0.97 oz/t Ag and 0.40% Cu over an average true width of 1.16 meters.
