DYNACOR RECEIVES COMMUNITY APPROVAL TO DRILL TEST TUMIPAMPA
Dynacor Gold Mines Inc. has received community approval to drill test the disseminated zone of its flagship gold project, Tumipampa. Dynacor will now apply for the exploration permit from the Ministry of Energy and Mines. The corporation is preparing a drilling campaign of the high-priority targets immediately after the rainy season.
Dynacor has also released significant surface results obtained in the disseminated gold zone at Tumipampa during the third quarter of 2017. The mineralogy of the samples was studied using a spectroradiometer and photomicrography.
Exploration highlights
Gold: 25 per cent of the 104 surface channel samples had anomalous Au grades above 0.05 gram per tonne or (0.05 part per million), ranging from 0.05 g/t to 16.52 g/t; Silver: 28.8 per cent of the 104 surface channel samples had anomalous Ag grades above 1.5 g/t (1.5 ppm), ranging from 1.5 g/t to 268 g/t; Copper: 26.9 per cent of the 104 surface channel samples had Cu grades above 100 ppm, ranging from 100 ppm to 762 ppm; Molybdenum: 22.1 per cent of the 104 samples had Mo grades above five ppm, ranging from five to 66.6 ppm; Lead: 11.5 per cent of the 104 samples had Pb grades above 250 ppm, ranging from 250 ppm to 3719 ppm;Free gold particles: high-definition photomicrography revealed the presence of free gold grains in a highly altered epithermal matrix within the quartzites.
Surface sampling
During the third quarter of2017, a surface sampling campaign was undertaken targeting the Sumac brecciated zone, 600 metres long and 300 m wide, located in the southeast of the disseminated gold zone at Tumipampa. Mineralization in this zone is delimited by the Diana and Adriana faults. The results are presented in the associated table and show a very significant percentage of anomalous samples.

Mineralogical Studies
Mineral identification of altered rock samples was carried out using a Terraspec spectroradiometer (Terraspec 4 Hi-Res). Selected samples were also studied using a photomicrography microscope in order to precisely determine the mineralogical composition.
The data obtained using the spectroradiometer conclusively demonstrated the presence of alteration minerals such as dickite, kaolinite, alunite, illite and sericite, which are formed by epithermal alteration processes. These alteration minerals, when they are found in an altered matrix of epithermal alteration, are often associated with anomalous values in gold, silver, antimony, arsenic and barium.
As shown in a photograph available on-line, free gold grains (approximately 20 microns to30 microns) occurring in a limonite matrix have been identified in samples taken from the hydrothermal quartzite breccias.
2018 exploration
This year, Dynacor will begin a drilling program on the disseminated gold zone. The drilling targets have been defined based on all the available geological data -- including the data reported in this press release, historical geochemical sampling data, reinterpretation of the geophysical data -- and the recommendations of independent experts (in disseminated gold deposits) who visited the property last fall.
The drilling program will begin immediately after the rainy season and will target the disseminated gold zone, in particular the Sumac breccia zone. The approved budget is $2-million (U.S.) to $2.5-million (U.S.) dollars over the next 18 to 24 months.
