“These first-ever Saddle South core results reveal a high-grade epithermal vein system bearing the key hallmarks – high grades, widths, and continuity – required to advance the project,” says Kevin Keough, President & CEO. “Saddle South appears to be evolving in the direction of robust, high-grade underground potential, with expansion drilling continuing to deliver a steady flow of fresh intercepts, now to 320 metres down-dip, and we’re rapidly pushing out, and deeper. It’s commonly the case, as in TTD004 and TTD005, that we achieve multiple high-grade intercepts in each hole, often encompassed by broader mineralized envelopes. Cumulatively, these multiple intra-hole intercepts really add-up. We’re generally rewarded with great visuals and have been encouraged by our ability to consistently drill three and even four holes per pad, each below the previous, and to walk it deeper. Step-outs along strike have been successful, with a bias toward the west, and our first three deep step-backs have also hit. In a couple of very steep holes, TTD003 and TTD006, we appear to have drilled down or sub-parallel to dykes sharing – as is so often the case in structurally-focused gold systems such as Saddle – the structural volume with the mineralization, but we can successfully avoid this by stepping back and coming at the target with lower angle holes.
In general, we’ve experienced rapid discovery expansion and gained confidence we can follow the mineralization with the drills down and laterally. The field crew, led by VP Exploration Charlie Greig, has been doing an outstanding job, and our results to date are a testament to their diligence and hard work. Our focus will continue to be on expansion, and painting the largest possible picture before season’s end. We intend to drill the Saddle discovery as long as the weather allows, and look forward to delivering more good news.”
Comments, VP Exploration:
“Our GT Gold crew and contractors, which includes a large proportion of both local Tahltan and other northern BC-based First Nations workers, have been working exceptionally hard in the field to unfold this discovery,” says Charles Greig, VP Exploration, “And the effort is paying off. Our hit in TTD007 is terrific, and has clearly validated the potential evident in the spectacularly elevated soil geochemistry at Saddle South and documented in earlier news releases. Like most other significant intersections at Saddle, the high grades in this hole are associated with semi-massive to massive sulphide quartz-calcite veining in the range of S.G. 3.1-3.7, but in this case the sulphides are relatively enriched in chalcopyrite, with elevated bismuth accompanying the copper. What’s exciting is that we’ve also observed this chalcopyrite enrichment over strong down-hole widths in a number of recently-drilled Saddle South holes for which we have yet to receive assays. We believe the very high-grade shoots, one of which the TTD007 intercept evidently has tapped into, may rake down to the southwest within the structural panel. We’re obviously going to try to stay onto these shoots and follow them with the drills and, as matters are unfolding, we appear to be succeeding.
With the experience of 36 core holes behind us, our efforts to stay on-target are now greatly helped by our visual estimates of mineralization in core, even for the more-subtle varieties. Our ability to visually predict what will run and what will not is excellent, and a credit to the quality of our geological and geotechnical team at Saddle. To date we’ve drilled over 7,100 metres on Saddle South and North combined, with the bulk of it at Saddle South. We intend to push hard until that time when weather conditions make continued drilling difficult, with the main aim being expansion of the vein zones along trend and down-dip, and as weather conditions at the higher elevations of Saddle South deteriorate, with more reconnaissance-style drilling at Saddle North.”
Saddle South Diamond Drilling, Geophysics, and Petrography
Inclusive of the 8 holes reported in this press release, 34 HQ-diametre diamond drill holes totalling over 6,500 metres have now been completed at the Saddle South discovery and two at Saddle North (see below), with Saddle South intercepts from drill set-ups spanning 320 metres east-west and as deep as 330 metres (TTD035) down-dip from surface. Within the great majority of these holes, multiple zones display high (hundreds of ppm) to very high (thousands of ppm) XRF values for the key Saddle pathfinder elements As, Pb, Zn, and Cu, which are strongly indicative of gold-silver content. Low XRF pathfinder values commonly manifest in the wallrock and post-mineral dykes between these zones.
A second core drill was added to the program on August 15 and both are currently active at Saddle South, where drilling is focused on extending the discovery down dip and along strike. Given the ongoing drilling success, drilling is now targeted to continue as late in the season as the weather allows. If the weather is favourable, a further 6,000 metres of drilling beyond current levels is anticipated. The ongoing diamond drill program is expanding upon the successful 28-hole, 1,527-metre program of reverse circulation drilling carried out in late June, the results of which were announced on July 25, 2017.
Core drilling has provided a greatly improved understanding of the geology and mineralization of the Saddle South prospect, and indicates that the mineralized structural panel trends east-west and variably dips from 60 to 80 degrees south. Diamond drill collars are predominantly located south of the projected surface trace of the structural panel, and are drilled to the north at varying dips. Holes are therefore ideally situated for intersecting the target optimally, resulting in intercepts that approach true widths in the minus 45 to 50-degree holes such as TTD007. Where topography presents challenges drilling to the north, such as on the west side of the Saddle South tableland, several recent holes have been successfully drilled due south.
Drilling to date also indicates that the structural panel hosting the gold and silver is occupied in part by steeply dipping dykes which, depending on how they are intercepted in drilling, are believed to block out (in industry parlance “dyke-out”) mineralization. The Company has been able to successfully complete several holes from each pad and to follow the mineralization to depth. However, in practice this has meant that the steepest holes from each set-up, for example holes TTD003 and TTD006, tend to drill sub-parallel to the dip of (and therefore along or within) the non-mineralized dykes. This outcome can be successfully avoided by stepping back and coming at the target with shallower-angle holes.
Ground-based Induced Polarization (“IP”) geophysics has demonstrated that the Saddle South mineralization is coincident with an excellent and quite focused IP and resistivity (low) response. The IP program carried out in June provided a view to only about 150 metres depth. As drilling to date suggests the Saddle South mineralization continues along strike and may have deep-seated roots, a program of deeper-looking borehole IP has just concluded at the Saddle South prospect, the results of which are being used to guide current drilling.
Selected samples of Saddle South drill core representative of the various styles of mineralization, alteration and host rocks were sent to a B.C. lab for petrographic work. Some results from this work, including thin sections of the high-grade mineralization intercepted in TTD007, have now been received. These images clearly show the close association between gold, pyrite and chalcopyrite, and have been posted to the Company website for viewing.
Saddle North Geophysics and Drilling
An IP ground geophysical survey carried out in June this year revealed a large target comprising both chargeability and resistivity anomalies trending for more than a kilometre east under glacial cover from the known Saddle North gold-in-soil anomaly. The glacial cover is believed to in part mask the gold-in-soil geochemical response, giving it a discontinuous appearance. Because the IP target remained open off-grid to the east at the close of the June program, and because local outcrops in that area display attractive quartz-sericite-pyrite alteration, an additional 10 line-kms of IP was undertaken to the east of the June grid, as shown in the plan view map accompanying this news release. The results of this work suggest the most prospective part of the anomaly, as defined by coincident geochemical and geophysical anomalies, is the narrower western ‘arm’ which strikes into the known strong gold geochemical anomaly.
Prior to the expansion of the IP survey, two reconnaissance holes totalling 597 metres were completed late in July on the western ‘arm’ of the IP anomaly, and drilled to the northeast. The first hole, TTD011, encountered difficult ground conditions and was shut down not far short of the targeted IP high. Nonetheless, the hole achieved a narrow visual+XRF intercept of Saddle-style mineralization, a photo of which may be downloaded from the website homepage. A follow-up hole is planned to complete the testing of this portion of the IP target from a new pad to be set up to the northeast of the site of TTD011, drilling back, azimuth southwest.
A second reconnaissance hole, TTD012, drilled from a setup 440 metres northwest of TTD011 and also drilled to the northeast, achieved its objective. This hole tested an IP response lower in intensity than that targeted by TTD011, in the process intercepting Saddle-style mineralization exhibiting a strong XRF response. Assays for this intercept are pending but if, as expected, the intercept returns gold values, it will confirm the potential of Saddle North as a target of considerable importance.
Additional drilling in follow-up to the initial intercepts at the Saddle North target, which is located in the more sheltered valley bottom, is planned for September, when weather is expected to force withdrawal from the exposed higher elevations of Saddle South.
Table 1 – Saddle South Diamond Drill Program Assay Results: Note: Turnaround times for assays were unusually long in July and August (1 month+), due to an upsurge in exploration activity in B.C. Widths reported below are drilled core lengths. True widths are estimated to be approximately 90% of drilled lengths for minus 45-degree holes, 70% for minus 70-degree holes, and about 50% for minus 85-degree holes. All assays are performed by ALS Canada Ltd., with sample preparation carried out at the ALS facility in Terrace, BC, and assays at the North Vancouver laboratory. Assay values are uncut. Assay results presented below are fire assay results only. For gold, fire assays are performed as per ALS protocol Au-AA26 (0.01-100.00 g/t Au) using 50 grams of sample with assays equal to or greater than 5 g/t Au calculated gravimetrically, and lower-grade samples measured by (AA) atomic absorption.

Table 2 – Remaining Saddle South RC Drill Program Assay Results: Note: Assay quality control checks for reverse circulation hole TTR025, drilled in late June, had indicated potential contamination of a single standard following in sequence a high-grade intercept. Accordingly, the standard and 5 samples on either side were re-run, resulting in an increase to the Au grade, the final results for which are presented below. True widths for the intercept are estimated to be approximately 75%.
