Puma Exploration Inc. and Trevali Mining Corporation (TV-TSX) (“Trevali”) released the drill results of the 2018 exploration drilling program conducted at the Murray Brook Deposit (MB Deposit). The program successfully confirmed the potential to discover additional resources at depth and on the west and south sides on the current know deposit. The exploration program at the MB Deposit consisted in 1,865 meters of drilling within two (2) new holes, and the extension of five (5) holes planned and drilled in regards to the metallurgical and geotechnical programs. The main objective of the exploration program was to evaluate and identify the areas of the MB Deposit which show the best potential to adding resources surrounding the actual deposit by extending the drill holes used for technical and mining design purposes.

The 2018 Exploration Drilling Program, in particular, with hole MB18-10, successfully confirmed the potential of finding significant new discoveries at very close proximity of the current known western side of the Murray Brook Deposit. Hole MB18-10, collared on the western side of the MB Deposit, was designed in view off the current geotechnical program with the first 0-250m not sampled yet. From 155 to 165 meters, the hole intercepted a new massive sulphide of Py-Sph-Cpy over 10 meters.

Once the geotechnical surveys are completed, the 10 meters of Massive Sulphide will be sampled and assayed. This intercept is located outside the current resource estimate. The hole was extended from 250 to 531 meters to verify and explore an untested area west of the MB Deposit toward the first priority drilling targets defined by the gravity, EM and geochemical surveys.

Predominance of fine grain sandstone was observed with an increasing amount of dark grey mudstone. A mineralized zone was discovered from 250 to 365 meters. The rocks are moderately to highly silicified where semi-massive to massive sulphides (mainly pyrite) predominates.

This pyrite mineralization and alteration zone grades 0.10 g/t Au over 110 meters and exhibits sub-perpendicular structures where the mineralization took place in the cleavage planes. Also, in the Pyrite Alteration Zone, low grade gold and zinc intercepts grading 0.14 g/t Au and 0.12% Zn over 30.90 meters were drilled. The gold and zinc content are well above the background found in the host rock at Murray Brook area.
