Metallurgical Studies Review

ALS Metallurgy ("ALS") of Kamloops, British Columbia, has been contracted to complete metallurgical studies for the Gladiator Gold Deposit. The metallurgical work will include at minimum; grind optimization, gravity separation, flotation, and cyanide leach testing. These studies are intended to provide an initial look at the characteristics of mineralization to help guide future optimization test work and processing flow sheet specifications. ALS will complete the work on approximately 45 kg of composite sample from the Main Zone from two wide diameter holes (MT-18-01, MT-18-02). Optimization work will continue as results are received and the Company does not anticipate disclosing results until completion in Q2-2018. Results from the metallurgical test work will be an integral part of the information to be used in the future potential engineering studies as we continue to de-risk the Gladiator Gold Deposit.

Winter Drill Program Review

The ongoing drilling campaign, totaling 70,000 meters in 2018, includes infill and definition drilling at the Gladiator Gold Deposit. The Winter Drill Program is comprised of five (5) drill rigs completing ~25,000 meters on the Gladiator Gold deposit, and is focused on definition drilling at a 50-meter drill hole spacing for the updated resource estimate in the second half of 2018. In addition, two (2) drill rigs, completing ~5,000 meters, have been deployed on regional exploration targets to the southwest (Coliseum Zone) and to the northeast (St. Cyr Zone).

Both the preliminary metallurgical studies and accelerated drill programs are on schedule and budget, ensuring the completion of our mineral resource update in the second half of 2018.
