Challenger Exploration Announces Results from the Company's Next Four Drillholes from the El Guayabo Gold-Copper Project in El Oro Province, Ecuador
Challenger Exploration announced results from the Company's next four drillholes from the El Guayabo Gold-Copper Project in El Oro Province, Ecuador. The results build on the results from the first two drill holes and confirm the discovery of a significant intrusion hosted gold-copper-silver-molybdenum system with all holes encountering wide zones of mineralisation associated with intrusives and intrusive breccias. The first six holes have intersected what is interpreted as a continuous zone of intrusion-hosted mineralisation 300 metres wide extending over 500 metres of strike to a maximum depth of 550 metres below surface. The mineralisation remains open in both directions along strike and at depth. The Company has two drill rigs on site with a depth capacity of 1,200 metres using NQ core rods. The Company is currently completing GYDD-22-015 and GYDD-21-016 at its 100% owned El Guayabo tenement. These holes were added to the program to follow up the mineralisation intersected in GYDD-21-006 and GYDD-21-008 (assays pending). GYDD-22-008 is logged as intersecting a 134 metre interval of the same style of intrusive breccia containing extensive sheeted veining as was intersected in GYDD-21-006 with a higher sulphide content than was logged in GYDD-21-006. Section 200 (GYDD-21-003 and GYDD-21-004): Drillholes GYDD-21-003 and GYDD-21-004 were collared approximately 200 metres west along strike from the Company's first drill hole GYDD-21-001 which intersected 784.3 metres at 0.4 g/t AuEq from near surface including a higher grade core of 188.5 metres at 0.6 g/t AuEq. Due to the steep topography to the south of the collar location limiting access the drill pad was located within the underlying gold in soil anomaly with GYDD-21-003 and GYDD-21-004 drilled from the same drill pad in opposite directions. While both holes intersected significant mineralisation (over 200 metres of mineralisation in both holes) the main zone of mineralisation is now believed to be 200 to 300 metres in width and dipping steeply. Accordingly both GYDD-21-003 and GYDD-21-004 are now interpreted as having drilled from within the zone of mineralisation through a near surface leached zone and then out of the mineralisation as shown in Cross Section. GYDD-21-003: GYDD-21-003 intersected 119.2 metres at 0.5 g/t AuEq (0.4 g/t Au, 0.8 g/t Ag, 0.02% Cu, 2.2 ppm Mo) from 71.8m. Below the 71 metre leached zone mineralisation is hosted in intrusives, intrusive breccia and metamorphic country rocks that have been brecciated by the intrusion. The mineralization included a higher grade zone of 77.2 metres at 0.6 g/t AuEq (0.5 g/t Au, 0.5 g/t Ag, 0.01 % Cu, 1.1 ppm Mo) from 76.4m including 26.2 metres at 1.1 g/t AuEq (1.1 g/t Au, 0.9 g/t Ag, 0.02 % Cu, 1.7 ppm Mo). GYDD-21-003 intersected three additional zones of mineralisation below the main zone including 15.0 metres at 0.4 g/t AuEq (0.3 g/t Au, 0.4 g/t Ag, 0.02 % Cu, 5.0 ppm Mo) from 356.5m and 21.4 metres at 0.3 g/t AuEq (0.1 g/t Au, 2.6 g/t Ag, 0.08 % Cu, 57.7 ppm Mo) from 675.8m, and 61.0 metres at 0.2 g/t AuEq (0.1 g/t Au, 0.9 g/t Ag, 0.05 % Cu, 24.5 ppm Mo) from 662.2m until the end of the hole. GYDD-21-004 GYDD-21-004 intersected 338.7 metres at 0.3 g/t AuEq (0.2 g/t Au, 1.0 g/t Ag, 0.03% Cu, 6.5 ppm Mo) from 37.1m including 27.0 metres at 0.6 g/t AuEq (0.5 g/t Au, 1.8 g/t Ag, 0.05 % Cu, 7.3 ppm Mo) from 348.8m. GYDD-21-004 intersected an additional zone of mineralisation below the main zone including 33.0 metres at 0.3g/t AuEq (0.2 g/t Au, 0.6 g/t Ag, 0.05 % Cu, 18.7 ppm Mo). Similarly to GYDD-21-003 the mineralisation is hosted in intrusives/intrusive breccia and below the zone of surface leaching and the mineralisation is consistent and pervasive. Section 300 (GYDD-21-005): Drillhole GYDD-21-005 was collared approximately 300 metres west along strike from GYDD-21-003 and GYDD-21-004. The hole was drilled in the same orientation as GYDD-21-004. Like GYDD-21-003 and GYDD-21-004 the collar position was affected by access issues due to the topography with the hole collared within the underlying gold in soil an omaly and drilled out. GYDD-21-005 intersected 581.7 metres at 0.3 g/t AuEq (0.3 g/t Au, 0.9 g/t Ag, 0.04% Cu, 2.4 ppm Mo) from 16.1m including 88.4 metres at 0.8 g/t AuEq (0.6 g/t Au, 1.8 g/t Ag, 0.09% Cu, 1.5 ppm Mo) from 389.8m, and 30.4 metres at 1.5 g/t AuEq (1.4 g/t Au, 0.9 g/t Ag, 0.03 % Cu, 5.1 ppm Mo) from 567.3m hosted in intrusives extending the zone of mineralisation 300 metres west along strike. Section 310 (GYDD-21-006) GYDD-21-006 was drilled from the same pad as GYDD21-005, however GYDD21-006 was drilled at an azimuth of 100 degrees rather than 150 degrees to better target a steeper zone of mineralization defined by the underlying gold in soil anomaly. The hole encountered a broad zone of mineralization from near surface predominantly hosted in intrusives and intrusive breccias intersecting 309.8 metres at 0.7 g/t AuEq (0.2 g/t Au, 6.2 g/t Ag, 0.21% Cu, 3.0 ppm Mo) from 3.3m. From 74.4 to 276.5 metres downhole GYDD-21-006 intersected a zone of intrusive breccia containing extensive sheeted veining logged as containing 6-20% total sulphides with an average sulphide content of 9.5% across the zone. The same interval returned an intercept of 202.1m at 0.8 g/t AuEq (0.3 g/t Au, 6.5 g/t Ag, 0.27 % Cu, 3.6 ppm Mo) from 74.4m including two higher grade zones of 33.0m at 1.3 g/t AuEq (0.3 g/t Au, 15.5 g/t Ag, 0.49% Cu, 3.7 ppm Mo) from 74.4m, and 53.6m at 1.5 g/t AuEq (0.7 g/t Au, 8.8 g/t Ag, 0.41 % Cu, 1.1 ppm Mo) from 231.9m.
