Dynacor: Discovery of a Large Copper-Gold Porphyry and Associated Skarns at Tumipampa
(firmenpresse) - MONTREAL, QUEBEC -- (Marketwired) -- 11/10/15 -- Dynacor Gold Mines Inc. (TSX: DNG)(OTC: DNGDF) (Dynacor or the Corporation) is very pleased to announce the discovery of a large copper-gold porphyry (1.7 km long) in the northwest area of its 100 % owned Tumipampa property. Detailed geological mapping, geophysical data and rock geochemical data (344 assays) were compiled and led to the discovery of this copper-gold porphyry and associated skarn structures.
Highlights
Alonso Sanchez Dynacor's chief geologist has analysed all the data and has concluded:
Geology and Exploration Methodology
Exploration carried out in the northwest sector of the the Tumipampa property during the first 9 months of 2015 has revealed the existence of a large Cu-Au porphyritic system which has been named the "El Potro" porphyry system (see Photo 1 and Figures 1 and 2).
This porphyry is 750 m wide and extends 1,700 meters to the northwest and consists of a fine to medium grained porphyritic diorite intrusive with fine N315 degrees E oriented quartz veinlets mineralized with pyrite and chalcopyrite. The intrusive has weak to moderate chloritic alterations (chlorite-magnetite-pyrite assemblages) and moderate propylitic alterations (epidote, weak chlorite-carbonate-pyrite, with a weak chalcopyrite assemblage). The porphyry is cut by three veinlet events. Two of the predominant veinlets are oriented N315 degrees E and N344 degrees E (see Photo 2) contain quartz-magnetite-chalcopyrite (Qz-Mt-Cpy) and Mt-Cpy and the third veinlet oriented N066 degrees E and N097 degrees E that contains only quartz. The sulphides are irregularly distributed (disseminated and in veinlets) and with fine chalcopyrite associated with the quartz veinlets.
The geophysics, ground magnetic and IP (induced polarization) - chargeability, show anomalies associated with this type of mineralization consisting of disseminated chalcopyrite and magnetite in the veinlets.
All told 344 surface channel samples and surface rock chip samples were collected and analyzed. Directly on the "El Potro" porphyry 221 samples were collected and 15 samples in a skarn located within the porphyry. Finally 108 samples were taken from Skarn 4 area.
Within the porphyry 25 surface samples are anomalous in copper between 0.012% Cu to 0.22% Cu (Table 1) and 14 samples anomalous in gold between 0.10 g/t Au to 2.51 g/t Au (Table 2).
All of the 15 samples collected in the skarn located within the porphyry had anomalous values of Ag, Cu, Mo, Pb or Zn with values as high as 40.4 g/t Ag, 0.438% Cu, 108 ppm Mo, 0.996% Pb, and 2.26% Zn. (see Table 3).
Fifty (55) samples of the 108 samples taken in Skarn 4 area returned anomalous values in copper between 0.01% Cu to as high as 3.63% Cu (see Table 4) and 19 samples returned anomalous values in gold between 0.13 g/t Au and as high as 9.59 g/t Au (see Table 5).
Finally, Jean Martineau Dynacor's CEO and President has commented "I am very pleased that we have found a large Cu-Au porphyry and its associated skarns since this opens a window of opportunity for Dynacor to make further discoveries of mineralized structures on this amazing property. Our geologists are very optimistic and are now planning how best to further the exploration of this area."
Additional underground exploration results from the cross-cuts are pending and will be released as soon as they are available.
Sample Analysis and QA/QC procedures
The samples were sent to the internationally certified laboratory ALS CHEMEX S.A. for analysis. Samples were assayed by ICP-AES, ICP-MS and AAS analysis. Standards, blanks and duplicates are used in the sampling process as part of the QA/QC methodology. Additional check and spot check samples were sent to SGS del Peru S.A.C. The program, sampling, collection of samples and the QA/QC was implemented and followed by Alonso Sanchez, Chief Geologist for Dynacor Gold Mines, B.Eng.

ABOUT DYNACOR GOLD MINES INC.
Dynacor is a gold ore-processing and exploration Corporation active in Peru since 1996. The Corporation differentiates itself from pure exploration companies as it generates income from its wholly owned ore-processing plant. Dynacor's basic share count at 37.4 million outstanding is in the lowest quartile of the resource sector. The Corporation's assets include three exploration properties, including the advanced high-grade gold Tumipampa property and an operating 85.000 TPA gold and silver ore processing mill at Metalex-Huanca. The Corporation obtained its permit to construct a brand new 300 tpd mill in Chala Peru. This represents an important milestone for the Corporation's future growth. The Corporation's strength and competitive advantage comes with the experience and knowledge it has developed while working in Peru. Its pride remains in maintaining respect and positive work ethics toward its employees, partners and local communities.
