Tiger Gold Corp. Reports Assay Results from Initial Drill Program at Dos Quebradas
Tiger Gold Corp. reported assay results from two of three holes drilled in its initial exploration program at Dos Quebradas. Drilling at Dos Quebradas forms part of Tiger's broader 20,000-meter drill program at its Quinchía Gold Project in Colombia's prolific Mid-Cauca gold belt. Three diamond drill rigs are currently active across the project, with assays pending from Dos Quebradas, Tesorito, and Ceibal. QDQDH-27 returned 282.45 meters @ 0.6 g/t Au from 18 meters downhole, including: 32 meters @ 1.3 g/t Au, and 21.23 meters @ 1.6 g/t Au. QDQDH-25 returned multiple gold intervals across a 631.1-meter hole. QDQDH-26 intersected mineralized breccia on same section line as QDQDH-27. Assays pending for QDQDH-26 and for additional holes at Tesorito and Ceibal. Dos Quebradas has a historical Inferred Mineral Resource estimate of 459,000 oz Au (20.2 Mt at 0.71 g/t Au) reported under the 2012 JORC Code. The Dos Quebradas estimate is historical, and a qualified person has not done sufficient work to classify this estimate as current, and Tiger is not treating it as current. The results reported in this release relate to drillholes QDQDH-25 and QDQDH-27. All intervals are reported as downhole lengths and true widths have not been determined. Assays for drillhole QDQDH-26 are pending. QDQDH-27 was drilled to 300.45 meters and returned 282.45 meters grading 0.6 g/t Au from 18 meters downhole and ended in mineralization, including 1.3 g/t Au over 32 meters and 1.6 g/t Au over 21.23 meters, as detailed in Table 1. The hole was collared into saprolite and passed through a tuff sequence before entering an inter-mineral magmatic breccia and diorite complex beginning at approximately 113 meters downhole. The upper higher-grade interval of 32 meters grading 1.3 g/t Au from 22 meters is hosted within a strongly oxidized tuff sequence with quartz-magnetite ("QM") type veins and abundant magnetite veins, while the deeper interval of 21.23 meters grading 1.6 g/t Au from 131.17 meters coincides with inter-mineral magmatic breccia and associated late and early diorite intrusions with A and B type veins. Below the breccia-diorite complex, the hole transitions into early diorite and basalt, and terminated in mineralization, indicating that the system remains open to depth. Elevated copper and molybdenum values are present throughout the mineralized interval and increase within the breccia-diorite complex (Table 1). The higher-grade interval from 131.17 meters to 152.4 meters returned 0.14% Cu and 37 ppm Mo alongside 1.6 g/t Au over 21.23 meters. The spatial correlation between gold, copper, molybdenum, and alteration assemblages within the breccia host rock is consistent with the porphyry Au-Cu-Mo signature and alteration framework described in the Mineralization and Geological Setting section below. QDQDH-25 was drilled to 631.1 meters and returned several gold intervals distributed across much of its length, as detailed in Table 1. The strongest interval was 60 meters grading 0.3 g/t Au from 28 meters, hosted within tuffs and inter-mineral magmatic breccia. The hole also returned 46 meters grading 0.3 g/t Au from 109 meters within the broader breccia complex. Geological logging records a long section of inter-mineral magmatic breccia from approximately 99 meters to 303 meters, with additional intervals of 20.8 meters grading 0.2 g/t Au from 284 meters and 20.42 meters grading 0.3 g/t Au from 315 meters intersected within and below this zone. In the deeper part of the hole, 52 meters grading 0.2 g/t Au from 388 meters was intersected, with late diorite and additional breccia phases encountered at depth. Copper and molybdenum values are low in the shallow intervals but increase with depth: the 52-meter interval from 388 meters to 440 meters returned 48 ppm Mo, and 0.2 g/t Au, and a 10-meter interval from 366 meters returned 128 ppm Mo and 0.2 g/t Au. This vertical zonation pattern, with copper and molybdenum strengthening at depth relative to gold, is consistent with zonation observed in porphyry systems. The wide distribution of gold is associated with QM veinlets in wall rock, including basalts and magmatic breccia. The extent of this mineralized envelope, even in lower-grade sections, is consistent with a broad hydrothermal system. QDQDH-26 was drilled to 343.1 meters on the same section line as QDQDH-27. The hole intersected inter-mineral magmatic breccia near surface, followed by basalt with intervals of early diorite, intra-mineral diorite, and additional breccia phases at depth. Assays are pending and will be reported in a subsequent news release. Dos Quebradas is located within the Quinchía Gold district in the prolific Mid-Cauca belt of Colombia, part of a cluster of deposits exhibiting multiple styles of mineralization including porphyry, epithermal vein, and hydrothermal breccia. Mineralization is primarily hosted within a porphyry-related intrusive and breccia complex emplaced at the contact between tuff of the Combia Formation and basalts of the Cretaceous basement, with surrounding volcanic and volcaniclastic country rocks. Tiger's and prior operator drilling has defined a mineralized footprint of approximately 400 meters by 350 meters that remains open for expansion. At Dos Quebradas, gold mineralization is primarily hosted within a multi-phase complex of inter-mineral magmatic breccias and diorite intrusions emplaced along the diorite-basalt contact zone. Gold and copper are associated mainly with B- and QM-type veinlets and in less proportion with A-type veins. Sulfide mineralogy includes pyrite, chalcopyrite, bornite, and minor molybdenite, with sulphide content increasing in later intrusive phases. Prior to drilling, Tiger undertook a comprehensive geological review of the Dos Quebradas prospect, including re-logging of drill core, geological mapping, surface rock sampling, and a reassessment of the surface channel sampling results from 2022. On November 8, 2022, LCL Resources Limited reported results of 146.6 meters grading 1.82 g/t Au, including 34 meters grading 4.22 g/t Au and 40 meters grading 2.16 g/t Au. These results are from continuous 2-meter channel samples taken within the saprolite profile above the Dos Quebradas mineralized zone. Shallow auger sampling confirmed the presence of near-surface gold mineralization, supporting the interpretation that mineralization extends below the weathered surface. Channel and auger samples were collected within deeply weathered saprolite of diorite and intrusive breccia. Near-surface grades may reflect supergene enrichment processes and are not necessarily representative of primary mineralization at depth.
