TDG Gold Corp. [TSXV-TDG] reported further high-grade, near-surface gold mineralization intersected in the final diamond drillhole completed in the 2023 exploration program at TDG’s 100%-owned Mets mining lease, located in the Toodoggone District of north-central British Columbia.
Diamond drillhole MT23-005 (HQ, oriented) was completed in the Mets A-Zone and intersected: 16.36 g/t gold, 4 g/t silver over 8.3 metres from 50.5 metres downhole depth using a cut-off grade (COG) of 3.00 g/t gold.
As stated previously, the high-grade gold mineralization at Mets appears to track a distinct very low frequency-electromagnetic (VLF EM) conductivity gradient coincident with a magnetic susceptibility low. This observation is consistent throughout the 50 metres of strike between drillholes MT23-004 and MT23-005/003. Further evaluation is underway to apply this interpretation across the known 130 metres of strike-length of the A-Zone, to generate targets for the potential southern and northern extensions of the A-Zone and, ultimately, explore across the entire mining lease.
MT23-005 was designed as a geological test of the potential controls on the northern extent of the A-Zone. The high-grade gold mineralization intersected extends the high-grade mineralized zone above hole MT23-003. Due to a mechanical issue with the drill rig, the drillhole was stopped at 74 metres downhole depth rather than the targeted 210 metres and hence failed to test the northern controls at depth.
Steven Kramar, TDG’s VP Exploration, commented: “The five diamond drillholes completed at Mets in 2023 validate the continuity of shallow, high-grade gold mineralization within the A-Zone. In combination with TDG’s high-resolution geophysics completed across the Mets mining lease, along with the recompiled historical information, we are developing a targeting framework and look forward to refining targets, starting with the potential extensions to the north and south of the A-Zone1.”
Drillhole MT23-005 is interpreted to have intersected the same quartz-barite breccia style of mineralization as MT23-001 and MT23-002/MT23-003 and MT23-004. This limited drill program validates the continuity of the high-grade historical drilling and demonstrates potential to expand on the high-grade A-Zone.
The final drillhole of the 2023 Mets drill campaign was designed to collect structural geological data by drilling oblique to previous drilling and examine the potential for high-grade mineralization on the other side of the previously untested N75 fault, as well as testing for potential additional structures. MT23-005 intersected high-grade gold in the vicinity of the intersection reported from MT23-003 and may expand the previously interpreted high-grade zone. The drillhole was terminated early at a shallow depth (74 m), well before reaching the N75 fault and its target depth of 210 metres due to mechanical issues on the drilling rig.
The casing was left in the drillhole so that TDG can re-enter the hole and complete drilling in the future. Historical trenching in the vicinity of MT23-005/003 reported results ranging from 0.04-15.0 g/t gold in 1-metre composite chip sampling over 48 metres of the trench-length sampled.
Short wave infrared light (SWIR) analysis was undertaken on all the core drilled at Mets in 2023. Further interpretations are currently underway to fully characterize alteration. SWIR responses can be non-unique, and X-Ray Diffraction (XRD) analysis is required to confirm mineral species present.
TDG is a major mineral tenure holder in the historical Toodoggone Production Corridor of north-central British Columbia with over 23,000 hectares of brownfield and greenfield exploration opportunities under direct ownership or earn-in agreement. TDG’s flagship projects are the former producing, high-grade gold-silver Shasta and Baker mines, which produced intermittently between 1981-2012, and the historical high-grade gold Mets developed prospect, all of which are road accessible, and combined have over 65,000 metres of historical drilling. The projects have been advanced through compilation of historical data, new geological mapping, geochemical and geophysical surveys and, at Shasta, 13,250 metres of modern HQ drill testing of the known mineralization occurrences and their potential extensions.
In May 2023, TDG published an updated Mineral Resource Estimate for Shasta which remains open at depth and along strike. In January 2023, TDG defined a larger exploration target area adjacent to Shasta. In 2023, TDG published the first modern drill results from the Mets mining lease.
