GT Gold Drills 1150 Metres1, From Surface, of 0.62 g/t Au, 0.36% Cu, 1.17 g/t Ag (0.82% CuEq2; 1.12 g/t AuEq2) in Saddle North Hole TTD109, Including 343 Metres of 1.28 g/t Au, 0.57% Cu, 2.30 g/t Ag (1.53% CuEq; 2.08 g/t AuEq)

 

 

 

 

 

GT Gold Corp. (TSX-V: GTT) is pleased to announce that the final and deepest hole of the Company’s 2018 Saddle North porphyry drill program, hole TTD109, has returned the strongest intercept to date. The results confirm the presence of a high-grade stockwork- and sheeted vein-rich “core zone” encompassing grades exceeding 1.0% CuEq2 and 1.5 g/t AuEq2 on Section 5740 (see Figures 1-2), which reaches from near surface (hole TTD108) to greater than 1,300 metres down-dip, where it remains open, with associated true widths that approximate 100 metres near surface in hole TTD108, expanding with depth to greater than 300 metres in holes TTD093 and, 300 metres farther down-dip, in TTD109. 

 

Results from the previous 10 holes at Saddle North (see news Sept. 10, Oct. 10, Nov. 19 and Dec. 12) demonstrate that this high-grade core zone extends to at least 500 metres of strike (e.g., hole TTD102), and that it lies within a much broader, strongly mineralized envelope which has a drilled strike length in excess of 650 metres, a true width of approximately 700 metres, and a down-dip extent of more than 1,300 metres.  A full geological compilation and interpretation is now well underway, and planning has begun for the 2019 drill campaign.  Results for the remaining 22 holes from the Saddle South target area are expected prior to the end of January.

 

Highlights

 

  • TTD109: 0.62 g/t Au, 0.36% Cu, 1.17 g/t Ag (0.82% CuEq2; 1.12 g/t AuEq2) over 1149.70 metres1 from 11.33 to 1161.00 metres
    • Including 0.84 g/t Au, 0.44% Cu, 1.52 g/t Ag (1.07% CuEq; 1.46 g/t AuEq) over 776.58 metres from 384.42 to 1161.00 metres
    • Including 1.28 g/t Au, 0.57% Cu, 2.30 g/t Ag (1.53% CuEq; 2.08 g/t AuEq) over 342.50 metres from 740.00 to 1082.50 metres

 

 

“As with previous holes from Saddle North, our final hole of the 2018 Saddle North drill program delivers an exceptional porphyry-style gold-copper intercept and it’s a great way to begin 2019,” says Charles Greig, Vice-President of Exploration for GT Gold. “Hole 109 confirms we have a large, high-grade system with grades increasing to depth. With broad intercepts of mineralization returning grades in excess of 1.0% or 1.5% CuEq in holes 93 and 109, we are excited by the prospects for what may lie even deeper in this system. In just our first eleven holes at Saddle North we have outlined a truly significant copper-gold mineralized system consisting of a large, northwest-southeast trending zone encompassing an extensive high-grade core dipping and/or plunging steeply west-southwest. As hole 108 has already shown, the higher-grade mineralization comes very close to surface, and a high-grade core, hundreds of metres thick, has now been demonstrated in our deeper holes.”

 

Complete assay results for hole TTD109 are presented in Table 1 below, along with a drilling plan view (Figure 1) and a cross-section (Figure 2).

Saddle North Geology

 

The Saddle North intrusive complex appears to be similar lithologically to the porphyry system at the nearby Red-Chris mine, but with high-K calc-alkalic rocks predominating.  The host intrusive rocks comprise fine-grained equigranular to crowded hornblende feldspar porphyritic (quartz) monzonite or monzodiorite bodies, locally rich in sub-round inclusions. The youngest intrusive phase, a relatively narrow and variably mineralized inter-mineral coarse hornblende plagioclase porphyry, which is recognized in hole TTD109 and the other holes on section 5740, is better-mineralized in the deeper holes (e.g. TTD109 and 093).  This appears to contribute significantly to the increase in grade with depth. Along with chalcopyrite:pyrite ratios increasing in that direction and the potential for a deeper bornite zone, the prospects for further grade increases deeper in the system are excellent.  

 

The intrusive rocks at Saddle North are variably and commonly strongly altered by potassic (magnetite, potassium feldspar, biotite) or chlorite-sericite-silica alteration assemblages.  They appear to be bound on either side by relatively intense phyllic alteration assemblages (quartz-sericite-pyrite), as well as by peripheral propylitic assemblages (chlorite, epidote, +/- pyrite), mainly developed in Upper Triassic lapilli tuff or reworked lapilli tuff (debris flow conglomerate) of intermediate to mafic composition. Mineralization occurs in quartz-magnetite-pyrite-chalcopyrite veins and as closely associated disseminations, with the principal sulphide phases being pyrite and chalcopyrite.  

 

QA/QC Procedures

 

GT Gold has implemented a rigorous quality assurance / quality control program to ensure best practices in sampling and analysis of diamond drill core, the details of which can be viewed on the Company’s website at http://www.gtgoldcorp.ca/projects/tatogga/.

 

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.  For gold, fire assays are performed as per ALS method Au-AA26 (0.01-100.00 g/t Au) using 50 grams of sample measured by atomic absorption (AA).   Assays equal to or greater than 100 g/t Au are reanalyzed gravimetrically by method Au-GRA22.  Silver and copper are analyzed by ALS method ME-MS61 with a 4-acid digestion followed by ICP-MS analysis.
