GT Gold Corp. Oct. 16 reported that results from the latest five holes drilled at its Tatogga property in northwestern British Columbia has extended the Saddle North porphyry copper-gold system to a depth of 1,550 meters, or nearly a mile below the surface.

Since first tapping Saddle North during 2018, GT Gold has outlined a porphyry body that measures roughly 1,500 meters down-plunge, 700 meters along strike and is 200 to 560 meters thick. Within this broader zone of mineralization is a core of higher-grade mineralization that measures roughly 1,400 meters down-plunge, 300 meters along strike and 40 to 450 meters thick.

"The grade, size, and geometry of the Saddle North porphyry system makes this amenable to a bulk mining operation, both open-pit as well as underground," said GT Gold CEO Paul Harbidge. "With its proximity to infrastructure and location within the tier-1 mining jurisdiction of British Columbia, Canada, this makes for a very compelling project."

Highlights from holes that have tapped the high-grade core since its discovery last year include:

• 904.1 meters of 0.51 g/t gold, 0.3 percent copper and 0.93 g/t silver in TTD093;

• 1,149.7 meters averaging 0.62 g/t gold, 0.36 percent copper and 1.17 g/t silver in TTD109; and

• 685 meters of 0.7 g/t gold, 0.44 percent copper and 1.09 g/t silver in TTD112;

Additional highlights from previously reported results from drilling at Saddle North include:

• 303 meters of 0.45 g/t gold, 0.38 percent copper and 1.04 g/t silver from a depth of 43 meters in TTD113;

• 431 meters of 0.46 g/t gold, 0.33 percent copper and 0.91 g/t silver from a depth of 17 meters in TTD116;

• 964 meters of 0.43 g/t gold, 0.22 percent copper and 0.73 g/t silver from a depth of 34 meters in TTD121;

• 396.5 meters of 0.37 g/t gold, 0.31 percent copper and one g/t silver from a depth of 7.5 meters in TTD125; and

• 1,206 meters of 0.57 g/t gold, 0.26 percent copper and 0.96 g/t silver from a depth of 18 meters in TTD126.

Three of the newly reported holes – TTD128, TTD129 and TTD130 – have extended the known higher-grade copper-gold core at Saddle North down-dip by approximately 150 to 200 meters, to a vertical depth below surface of 1,550 meters.

TTD128 cut 635 meters averaging 0.40 g/t gold, 0.31 percent copper and 0.93 g/t silver from a depth of 696 meters. This includes 225.4 meters of 0.74 g/t gold, 0.46 percent copper and 1.57 g/t silver from 1,083.8 meters; and 137.6 meters of 0.52 g/t gold, 0.36 percent copper and 1.38 g/t silver from 1,353 meters.

TTD129 intersected 793 meters averaging 0.46 g/t gold, 0.38 percent copper, 1 g/t silver from 488 meters. This includes 355 meters of 0.61 g/t gold, 0.45 percent copper and 1.25 g/t silver from 642 meters; and 230 meters of 0.42 g/t gold, 0.29 percent copper and 1.25 g/t silver from 1,291 meters.

The results from these two holes show that the deepest and highest-grade copper-gold mineralization at Saddle North remains open to depth.

TTD130, on the other hand, tapped the high-grade core between these deeper holes and the higher-grade mineralization previously encountered in holes TTD109 and TTD093.

TTD130 cut 599 meters of 0.52 g/t gold, 0.30 percent copper and 0.90 g/t silver from 682 meters. This includes 343 meters of 0.63 g/t gold, 0.34 percent copper, 1.02 g/t silver from 890 meters.

The highest-grade intercept in this latest batch of holes came in TTD132, which was drilled as a "cross-hole" to link the higher grade mineralization encountered in holes TTD093, TTD109, TTD112, TTD121 and TTD126.

Drill hole TTD132 confirms continuity of the higher-grade core in the central part of the deposit, while extending near surface mineralization to the northwest.

Overall, GT Gold said the drilling so far at Saddle North has confirmed excellent continuity of mineralization with gold-copper grades generally increasing with depth.

The system remains open at depth, and highly prospective targets remain untested along strike to the west and southeast.

"It is great to see a set of strong drill results which is providing further delineation to this large-scale gold-rich porphyry copper system," said Harbidge. "It is very encouraging to see the continuity of the high-grade core drill hole to drill hole and section to section, especially with the results of TTD132 and the fact that the system remains open to depth and targets remain untested along trend."
