High-grade gold, copper, silver and tungsten assay results have been received for a further five holes from its ongoing drilling program designed to outline and expand the near surface zone of mineralization at the Apollo system with highlighted results as follows:442.35 metres @ 2.16 g/t gold equivalent (1.18 g/t gold, 43 g/t silver, 0.21% copper and 0.05% WO3) from surface (APC-125) including 68.05 metres @ 4.55 g/t gold equivalent. The hole bottomed while still in strong mineralization.325.10 metres @ 2.03 g/t gold equivalent (0.98 g/t gold, 27 g/t silver, 0.47% copper, and 0.03% WO3) from 8 metres below surface (APC-126)

High-grade gold, copper, silver and tungsten assay results have been received for the further six holes from the shallow drilling program designed to outline and expand the zone of mineralization with highlighted results as follows:397.50 metres @ 2.62 g/t gold equivalent (1.20 g/t gold, 60 g/t silver, 0.33% copper and 0.07% WO3) from surface (APC-122) with a grade accumulation of 1,041 gram x metres.

A new high-grade vein system has been discovered in hole MEC-2 at the ME target (located southeast of Apollo) with assay results as follows:0.65 metres @ 534.0 g/t gold from 274.5 metres downhole and0.90 metres @ 47.2 g/t gold from 291.8 metres downholeShortly after completing hole MEC-2 and at the onset of hole MEC-3, drilling was halted as the preliminary results from the new gravimetric survey were received by the Company, indicating that these holes were drilled outside of the gravity high. The Company interprets the new discovery in hole MEC-2 to be high-grade vein leakage from a potentially large, mineralized breccia body located within the gravity high to its immediate south. Drilling has recommenced at ME targeting the gravity high with additional results expected in due course.A new gravimetric survey was completed over a two-square-kilometre portion of the Guayabales Project covering the corridor running from the Apollo system to the concession boundary with Aris Mining's Marmato mine with compelling highlights as follows:Confidence in the survey is robust as it proved extremely effective in identifying Apollo as a gravity-high due to the high concentration of breccia hosted sulphides in the system. Seven new gravity anomalies, with near-identical gravimetric features to Apollo, have been identified within the survey corridor including one located directly southwest of Apollo named Apollo South, three in the ME target area, one in the X target area and two in the Plutus target area. Diamond drilling with two rigs to test both the ME and X gravimetric high anomalies will commence immediately with the balance of the gravity targets to be tested shortly thereafter.
