Triumph Gold Drills 106.50 m of 0.76 g/t AuEq and Expands the Blue Sky Zone at the Freegold Mountain Project, Yukon
The Blue Sky Zone is defined by 12 drill holes: three holes from the 2021 program (Table 1) and nine historical holes (Table 3). The Blue Sky Zone is a NE-striking, near vertical body of Au-Cu-Ag-Mo mineralization that remains open at depth. The Revenue Deposit is made up of the Blue Sky Zone, WAu Zone, and zones of Cu-Mo-Au porphyry-style mineralization.
The Blue Sky Zone has been expanded 100 metres westwards and towards the surface with a modeled strike length of 210 metres. The zone has an average width of 70 metres and a depth of 480 metres below surface. The 2021 drilling program expanded both the Blue Sky Zone and the WAu Zone and reduced the gap between the two zones to 65 metres (Figure 2).
46% of the 6,615 metres of the 2021 diamond drilling program have been reported to date (PR#21-11). Further updates will be provided when the results for the remainder of the 2021 exploration program are received and interpreted from the Nucleus Deposit, Big Creek South Fault Zone, the Orbit Zone, and regional exploration activities (Figure 1).

“We are pleased to report these exceptional drill results that support the teams’ geological interpretation of the Blue Sky Zone extending towards surface within the open-pit resource.We are excited that the WAu Zone and Blue Sky Zone continue to grow bulk-tonnage mineralization within the Revenue Deposit,” stated Brian May, President, Triumph Gold Corp.
Detailed Interpretation and Geology
RVD21-05 intercepted the Blue Sky Zone and returned 106.50 metres of 0.76 g/t AuEq from 120.00 metres. This intercept is located 60 metres southwest of RVD18-16, which had an intercept of 110.42 metres grading 1.86 g/t AuEq (PR#18-08). The 2021 program expanded the Blue Sky Zone 100 metres westwards and towards the surface (Figure 2). The updated expression of the Blue Sky Zone is now modeled to be 65 metres from the WAu Zone, suggesting the two zones may be linked in a NE orientation (Table 1 and Figure 2).
Mineralization at the Blue Sky Zone is hosted within hydrothermally-altered granodiorite and contains two overlapping mineralization events:
- The first and most abundant mineralization event is associated with strong potassic alteration with K-feldspar grading outwards into biotite, suggesting a high-temperature porphyry zone. Sulphide mineralization (chalcopyrite, molybdenite, pyrite and pyrrhotite) is characterized by clots, veinlets, and disseminations.
- The second phase of mineralization is hosted by epithermal quartz-calcite veins with mineralization of chalcopyrite, molybdenite, galena, sphalerite +/- bismuthinite and visible gold, representing metal enrichment.
Porphyry-style mineralization was intercepted south of the modeled Blue Sky Zone (Figure 2, Tables 1 and 4). Porphyry-style mineralization consists of local sulphide +/- quartz stockwork veining with broad zones of disseminated sulphide mineralization surrounding vein clusters and local fine grained native gold (Figure 4).

Significant intercepts in the three drill holes of this release are listed in Table 1 and are depicted by purple (Blue Sky Zone) and cyan bars (porphyry-style vein +/- disseminated mineralization). Historical Blue Sky Zone intercepts are depicted by blue bars and are listed in Table 3. Wireframes were generated using Micromine’s implicit modeling tool.

References and Disclosures
1 Gold equivalent [AuEq] is used for illustrative purposes, to express the combined value of gold, silver, copper, and molybdenum as a percentage of gold. No allowances have been made for recovery losses that would occur in a mining scenario. AuEq is calculated using US$1,750.00 per troy ounce of gold, US$24.00 per troy ounce of silver, US$4.00 per pound of copper and US$15.00 per pound of molybdenum:
AuEq = Au g/t + (Ag g/t X $24.00 / $1750.00) + (Cu% X $4.00 X 22.0462) / ($1750.00 / 31.10) + (Mo% X $15.00 X 22.0462) / ($1750.00 / 31.10)
Reported assay intervals are calculated using Micromine’s grade compositing tool using >0.25 g/t AuEq cutoff, constrained by no more than 6 metres of consecutive internal dilution. High-grade intervals are reported using >1.0 g/t AuEq cutoff with no more than 5 metres of consecutive internal dilution.
Reported assays are uncut weighted averages and represent drilled core lengths. The true width of reported mineralization is unknown.
2 Reinterpretation of the Blue Sky Zone was completed by reviewing historical drill holes along the NE trend. Geological data (core logs, assays, and core photos) was inspected for structural and geochemical signatures that match characteristics of the Blue Sky Zone. AuEq values are reported using current metal prices for both historical and newly identified intercepts.
Sample Preparation and QAQC
Diamond drill holes at the Freegold Mountain Project are drilled using HTW and NTW core sizes (70.92 millimetres and 56.00 millimetres diameter respectively). Drill core samples average 1.63 metres in length with a minimum length of 0.50 metres and a maximum length of 2.00 metres except at the top of RVD21-07 where core loss resulted in a sample length of 4.66 metres. Drill core is cut along the long axis of the core over the entire length of the drill hole. Sample intervals are defined by mineralization, lithology, structure, and alteration boundaries.
Sample preparation is completed at ALS Whitehorse with sample pulps shipped to ALS Vancouver for analyses. Samples are dried and crushed to 70% less than 2 millimetres with a 250-gram riffle-split and pulverized to better than 85% passing 75 microns (PREP-31).
A 50-gram sample from the pulp is analyzed for gold using fire assay techniques and atomic absorption spectroscopy with detection limits of 0.005-10 parts per million (“ppm”) (Au-AA24). Gold overlimit values are re-analyzed using a gravimetric finish with an upper detection limit of 10,000 ppm (Au-GRA22). A 0.25 gram sample from the pulp is analyzed with multi-element geochemistry (ME-ICP61) using a 4-acid near total digestion and induced coupled plasma atomic emission spectroscopy (ICP-AES) providing 33 elements (Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, K, La, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Sc, Sr, Th, Ti, Tl, U, V, W, Zn).
Sample Quality Assurance/Quality Control (“QAQC”) measures include unmarked certified reference materials (CRMs), rock blanks, and field duplicates are inserted into the sample sequence and make up 5% of the samples submitted to the lab for holes reported in this release. Additional QAQC checks are ongoing in accordance with 43-101 standards.
