Vancouver, B.C. July 6, 2021: Sun Summit Minerals Inc. (TSX-V: SMN; OTC: SMREF) (“Sun Summit” or the “Company”) is pleased to report the final assay results from the first phase of its 2021 exploration program on its Buck Property, central British Columbia.
Long intervals of continuous gold mineralization cut in BK21-033 (Horseshoe zone):
- 87 metres of 1.13 grams per tonne (g/t) gold equivalent (AuEQ) within 265 metres of 0.66 g/t AuEQ and 409 metres of 0.52 g/t AuEQ.
- 409 metre interval starts at six metres down hole and represents the longest zone of continuous gold mineralization intersected on the property.
- BK21-033 together with previously reported BK21-017 (241 metres of 0.77 g/t AuEQ, including 109 metres of 1.15 g/t AuEQ; May 11th, 2021 News Release) and BK21-032 (187 metres of 0.73 g/t AuEQ including 54.0 metres of 1.19 g/t AuEQ and a lower interval of 59.1 metres of 0.95 g/t AuEQ; June 10th, 2021 News Release) demonstrate significant bulk-tonnage gold potential of the northern-extent of the Horseshoe zone.
- Based on 2020 and 2021 drilling, the mineralized system at Buck is at least 950 metres east-west by 900 metres north-south, with limits not yet defined.
Note: Intervals are downhole core lengths. True widths are unknown. AuEQ based on a 65:1 silver to gold ratio.
Bob Willis, Sun Summit’s CEO, commented:
“The 2021 drill program is a clear success. All holes cut multiple intervals of strong gold mineralization associated with significant hydrothermal alteration. In addition, large step-out holes from previously drilled areas, have yet to constrain the limits of the epithermal-related mineralized system.
“In this final batch of assays, BK21-033 yielded 211 gram*metres (409 metres x 0.52 g/t AuEQ), the highest gram*metre intersection to date on the property. This drill hole, along with holes BK21-017 and BK21-032, demonstrates the potential of the northern extent of the Horseshoe zone. This will be a priority area to further drill test once we ramp up our drill program.
“We aggressively stepped-out 400 metres to the east and drilled through post-mineralization volcanic rocks and hit Horseshoe zone-style breccia mineralization right below the basalts. This exploration success significantly opens the eastern side of the property for gold zone expansion.
“All Trench zone holes in 2021 were designed based on results from one hole – discovery hole BK20-012 (17.0 metres of 5.89 g/t AuEQ including 3.0 metres of 23.10 g/t AuEQ). With no assays to guide hole placement while drilling was ongoing, we sited holes to maximize coverage within the known Trench-Horseshoe area, rather than trying to target specific high grade intercepts. Even so, drilling succeeded in delivering numerous additional drill intercepts of similar grade from this area. Our team is now working on a modified and still evolving geological model that we will use in generating our plan for the next phase of drilling. We plan to aggressively explore Buck with an expanded drill program as soon as this geological modelling is complete. The Buck gold mineralized hydrothermal system has been intercepted over an area of approximately 950 metres by 900 metres, based on drilling to date. Its limits and full extent are still unknown.
“We also look forward to reporting the results of our ongoing property-wide exploration program as they become available. Early indications from this work are encouraging and may add targets for drill testing sooner rather than later.”
Sun Summit has drilled 18 holes so far in 2021. Results from the first five holes were announced on May 11th, 2021 and results from six additional holes were announced on June 10th, 2021. Results from the final seven holes are reported in this news release (Tables 1, 2 and 3).
Drill hole BK21-033 was designed to test the lateral and depth extent of significant mineralization intersected in holes BK21-017 and BK21-018 (see SMN news release dated May 11th, 2021). Based on modelling of results from BK21-017 and BK21-018, BK21-033 was collared on the same pad as BK21-017 but drilled at a shallower dip and to the east. The hole cut long intervals of breccia-hosted, sphalerite-associated, bulk tonnage-style gold mineralization highlighted by 409 metres of 0.52 g/t AuEQ (211 AuEQ gram*metres) including 265 metres of 0.66 g/t AuEQ and 87 metres of 1.13 g/t AuEQ. The nature of gold-associated with zinc mineralization is similar to BK21-017 and BK21-032 – the 409 metre interval also returned 0.57% zinc.
Using the same interval calculation parameters as BK21-033 (i.e., 0.10 g/t AuEQ cut-off), BK21-017, when recalculated, intersected 241 metres of 0.77 g/t AuEQ (186 AuEQ gram*metres) including 109 metres of 1.15 g/t AuEQ (see SMN news release dated May 11th, 2021) and BK21-032, when recalculated, intersected 187 metres of 0.73 g/t AuEQ (137 AuEQ gram*metres) with 54.0 metres of 1.19 g/t AuEQ and a lower interval of 59.1 metres of 0.95 g/t AuEQ (see SMN news release dated June 10th, 2021). These long intervals of high gram*metres demonstrate the significant near surface, bulk-tonnage potential of the Horseshoe zone. These new data integrated with the Company’s exploration model, suggests that significant additional drilling is warranted to define the extent and trend of the broad mineralized zones.
Sun Summit drilled three widely-spaced step-out holes (BK21-030, 031 and 034):
- BK21-031 collared through over 160 metres of post-mineralization, Eocene aged basalts and bottomed in the same package of dacitic volcanic rocks, breccias, and quartz-feldspar porphyries as the core of the Horseshoe zone, centered 400 metres to the northwest. BK21-031 intersected pervasive hydrothermal-related alteration (quartz + sericite + pyrite) and yielded multiple long intervals of gold mineralization over the 167 metres of drilled Horseshoe-affinity volcanic rocks and intrusive dykes (Table 2). Additional drilling in this new area (Buck SE), is clearly warranted to further test the extent of epithermal-related mineralization and to target higher-grade zones, known to lie peripheral to the styles of alteration and mineralization observed in BK21-031 (e.g., BK21-033).
- BK21-034 collared over 700 metres northwest of BK21-033 (BK20-012, BK21-017) and targeted a northwest trending magnetic-low geophysical anomaly. The hole intersected a thick sequence of variably altered, andesitic volcanic and volcaniclastic rocks cut by local quartz-feldspar porphyritic dykes and a high-grade, base metal-rich, silver-bearing banded quartz vein. The vein returned an intercept of 1.3 metres of 329 g/t silver with 0.50 g/t gold, 1.40% zinc and 2.96% lead (Table 2).
- BK21-030, collared 200 metres southwest of BK21-033 (Figure 1), was drilled to the southwest to test a new area at depth previously undrilled. The hole cut numerous intervals of bulk tonnage-style gold mineralization (Table 2) and demonstrates a southern continuation of prospective Horseshoe-style breccias.
Drill holes BK21-027, 028 and 029 were collared in the Trench zone and were designed to test the extent of gold mineralization previously discovered in BK20-012 (17.0 metres of 5.89 g/t AuEQ including 3.0 metres of 23.10 g/t AuEQ; see SMN news release dated January 5th, 2021). Hole BK21-027 was collared on the same pad as BK21-025 (62 metres of 0.85 g/t AuEQ including 19.2 metres of 1.31 g/t AuEQ; see SMN news release dated June 10th, 2021) but drilled at a shallower angle to the west. Hole BK21-028 was collared 25 metres west of BK21-024 (17.0 metres of 2.97 g/t AuEQ including 1.4 metres of 19.71 g/t AuEQ and 1.4 metres of 14.01 g/t AuEQ; see SMN news release dated June 10th, 2021) and drilled to the southwest. BK21-029 was collared 180 metres south of BK21-028 and drilled to the northeast.
All three holes cut multiple intervals of broad zones of bulk tonnage-style gold mineralization hosted in pervasively sericite + quartz altered lapilli tuffs, andesites and quartz-feldspar porphyry dykes. Mineralization is predominantly disseminated and veinlet-hosted comprised of pyrite and sphalerite. Assay results from this zone are reported in Table 3.

All sample assay results have been monitored through the Company’s quality assurance and quality control (QA/QC) program. Drill core was sawn in half at Sun Summit’s core logging and processing facility in Houston, B.C. Half the core was sampled and shipped in sealed and secure bags to the ALS Global preparation facilities in Yellowknife, N.T. Samples were prepared using standard preparation procedures. Following sample preparation, the pulps were sent to the ALS Global analytical laboratory in North Vancouver, B.C., for analysis.
Core samples were analyzed for 48 elements by ICP-MS on a 0.25 gram sample using a four acid digestion (method ME-MS61L or ME-MS61). Gold was analyzed by fire assay on a 30 gram sample with an AAS finish (method Au-AA23). Over limit gold (>10 ppm) was re-analyzed by fire assay using a gravimetric finish on a 30 gram sample. Over limit silver (>100 ppm) was re-analyzed using a four acid digestion and ICP-AES finish. Over limit zinc (>10,000 ppm) and lead (>10,000 ppm) was re-analysed using a four acid digestion and ICP-AES finish. ALS Global is registered to ISO / IEC 17025:2017 accreditations for laboratory procedures.
In addition to ALS Global laboratory QA/QC protocols, Sun Summit implements an internal QA/QC program that includes the insertion of duplicates, standards and blanks into the sample stream.
