On the opposite side the drift (910SW point 7 on Figure 1) was excavated over 5 meters, four (4) channel samples returned an average grade of 16.11 g/t Au over 1.94 m (TW) including a grade of 69.39 g/t Au (uncut grade) over 0.40 m (TW) and a grade of 55.60 g/t Au (uncut grade) over 0.90 m (TW) (See Tables 2 and 4).

Underground Channel Sampling Methodology

A total of 234 meters of cross-cut and 40 meters of drift has been excavated to date as part of the 2015 exploration campaign. Seventeen (17) channel samples were taken in the two drifts and the results are given in Tables 1, 2 and 3 and 4. Tables 1 and 2 give the average results and widths for each channel sample. Each channel sample was taken directly in the structure at intervals between 1 and 3 metres apart and had a width of between 0.8 to 2.10 metres.

Each channel sample was also subdivided into 3 channel sub-samples from the floor to the roof of the mineralized sample. Each subsample weighed between 1.5 to 3 kilos and was sampled across 0.3 to 1.0 meters. The complete set of 48 channel subsample assays is given in Tables 3 and 4.

Outlook: Underground Drilling and Cross-Cut Programme

In April, Dynacor began its underground drilling campaign from the drilling station shown in Figure 1 at the 530-meter mark along cross-cut 330NW. The drilling will target the lateral and at depth extensions of the Manto Dorado, the Manto Nazareno and the Lisa Vein. At this date the underground drilling program of 2015 is on its fourth drill hole and results are pending.

In coming months, Dynacor will continue its underground exploration by advancing cross-cut 330NW and will begin the excavation of a 2^nd cross-cut 485NW located 40 meters below and 250 meters to the northeast of the entrance to cross-cut 330NW. Dynacor is also planning to extend existing drifts and excavate new drifts and chimneys. Full details of its exploration campaign have been published (see Press Release dated February 25, 2015).

Jean Martineau Dynacor's President and CEO has stated regarding this latest set of exploration results "I am extremely satisfied by these results since we have discovered two new gold mineralized structures at Tumipampa. The Lisa Vein returned several high grade assays and the Manto Nazereno although it shows lower grades they are quite constant which merits further investigation. Both structures will be further explored in the coming months. Finally, the discovery of two new gold mineralized clearly demonstrates the advantage of underground exploration using cross-cuts as compared to drilling from the surface."

Sample Analysis and QA/QC procedures

The samples are sent to the internationally certified laboratories Certimin S.A. and ALS Chemex del Peru S.A.C for analysis and checks of mineralized sections. Samples were assayed by ICP analysis and for gold assays greater than 10 g/t Au a gravimetric FAA finish assay is performed. Standards, blanks and duplicates are used in the sampling process as part of the QA/QC for the sampling in the cross cut. The program, sampling, collection of samples and the QA/QC is implemented and followed by Alonso Sanchez, Chief Geologist for Dynacor Gold Mines, B.Eng and QP under the American Institute of Professional Geologists (AIPG).

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 36.2 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 Huanca. The Corporation recently 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.
