Trillium Gold Mines (TSXV:TGM) (OTC:TGLDF) has reported new results from the Newman Todd Complex from drill holes NT21-195 to -203 and RV21-36A. The holes were last drilled in the final quarter of 2021, but due to a general backlog in assay laboratory turnaround, final results were only received in late March 2022.
This group of drill holes were intended to follow up on previous results and begin testing of newly interpreted east-west structural corridors cutting through the NT Zone.
William Paterson, Trillium Gold’s Vice President of Exploration commented in a press release: “We continue to intersect significant mineralization as we follow up on the known east-west structures within the NT Zone and have received additional significant results as we begin to test new interpreted structures further southeast along the NT Zone. Our structural model and interpreted controls on the gold mineralization seem to be holding up well. Further work is necessary, but we are confident that subsequent drilling will yield similar results as we continue our work. We also feel it is time to commence testing high-priority structural targets both east and west of the NT Zone in order to begin expanding the resource footprint in the greater project area.”
Highlights from the results are as follows:
- 4 metres @ 24.2 g/t gold including 1.15 metres @ 73.67 g/t gold from NT21-202 in a new east-west fault corridor more than 400 metres southwest along the NT Zone from the Main Zone Fault
- Wide zone of 15.5 metres @ 4.6 g/t gold containing 1.45 metres @ 35.86 g/t Au from 247 metres downhole in NT21-196
- Testing and confirming gold mineralization on multiple east-west structures cutting through the NT Zone
Hole NT21-195 targeted high-grade Rivard-style quartz vein mineralization along the footwall contact of the NT Zone where two of the more significant results were found in siliceous NT Zone breccia segments offset into the footwall along E-W faults.
Holes NT21-196 and -197 followed up on previous significant intersections associated with hole NT21-194 (9m @ 19.73 g/t Au) and the Camp Zone Fault (see NR dated September 23, 2021). Hole NT21-196 was drilled above hole NT21-194 and intersected mineralized portions of the NT Zone with veining containing visible gold (VG) associated with galena and sphalerite, located in the footwall contact area. Hole NT21-197 stepped back to collar in the Camp Fault area testing the down-dip continuity of mineralization and the E-W Main Zone Fault structure. Both holes returned numerous significant assay results; NT21-196 throughout the hole, with VG seen in quartz veins between 257.8m and 259.4m, and in the lower portion of NT21-197, in the Main Zone Fault area. See Figures 1 and 2.

In the south region of the Main Zone portion of the NT Zone, a series of holes (NT21-198 to -203) were drilled to the north and south across known and newly interpreted E-W breccia fault corridors crossing the NT Zone, often seen associated with better grade mineralization and Rivard-style quartz vein clusters along the fault trends. The Rivard-style vein intersected in NT21-202 at 262.25 – 264.2m contained multiple specks of VG and assayed 4m @ 24.2 g/t Au. All the holes returned grades and widths as expected, supporting the interpretation that these E-W structural corridors are influencing and focusing gold in the NT Zone.
In the southwest portion of the NT Zone, hole RV21-36A was drilled to assist in refining the model for the south portion of the NT Zone, as well as the SW Zone, and greatly extends the depth and extents of known mineralization. The hole first intersected the SW Zone showing patchy mineralization followed by a second breccia zone, towards the southeast, correlating to the NT Zone proper. In addition, the VG located in a sheared felsic volcanic section (at 695.5m) and in a quartz lens (at 705.5m), in the lower portion of the hole, expands the limits of VG occurrences cored in the project area. The E-W fault corridor associated with this gold mineralized zone is a new addition into our model for future targeting. Two very significant intercepts were received from this hole of 0.45m @ 17.5 g/t Au from 695.35m and 12m @ 3.08 g/t Au from 704m (including 1m @ 22.6 g/t Au). This hole was only stopped due to diminishing drill productivity.
