SUN SUMMIT DRILLS BROAD ZONES OF STRONG GOLD-SILVER-ZINC MINERALIZATION AT THE BUCK PROJECT, CENTRAL BC; INTERSECTS 186 METRES OF 0.66 G/T GOLD EQUIVALENT
Sun Summit Minerals Corp. has released initial results from its summer 2023 exploration drill program at the Buck Main target as part of a multistage exploration program across its 52,000-hectare Buck project in central British Columbia.
- Results from the first two drill holes indicate that significant gold (Au), silver (Ag) and zinc (Zn) mineralization extend laterally and at depth, and is open to the north where previous drilling is sparse:
- Hole BK23-086:
- 148.5 metres of 0.46 gram per tonne (g/t) gold equivalent (AuEq) (0.33 g/t Au, 4.2 g/t Ag and 0.31 per cent Zn);
- 40 metres of 0.68 g/t AuEq (0.57 g/t Au, 5.9 g/t Ag and 0.3 per cent Zn), including nine metres of 1.43 g/t AuEq (1.27 g/t Au, 8.9 g/t Ag and 0.58 per cent Zn);
- 10 metres of 0.83 g/t AuEq (0.6 g/t Au, 2.5 g/t Ag and 0.6 per cent Zn).
- Hole BK23-087:
- 185.9 metres of 0.66 g/t AuEq (0.39 g/t Au, 8.2 g/t Ag and 0.53 per cent Zn), including 1.5 metres of 5.59 g/t AuEq (4.10 g/t Au, 20.8 g/t Ag and 3.96 per cent Zn), 20.1 metres of 0.98 g/t AuEq (0.62 g/t Au, 3.3 g/t Ag and 0.87 per cent Zn) and 11.9 metres of 1.45 g/t AuEq (1.26 g/t Au, 7.4 g/t Ag and 0.64 per cent Zn).
- The broad gold, silver and zinc intervals reported in these holes supports the potential for depth extension of bulk-tonnage-style disseminated mineralization being delineated at Buck Main.
- Drilling at Buck Main is continuing, and assay results from the remaining holes are pending, with results expected as they are received and analyzed.
- Results from the extensive surface exploration program in the area of Mt Morice and CR (recently acquired from Teck -- see June 1, 2023, news release) are being analyzed and interpreted, and will be released shortly.
Sharyn Alexander, Sun Summit's president, stated: "The first two holes of our ongoing drill program at Buck Main indicate significant mineralization extends laterally and at depth. The consistent broad mineralized intercepts in this area of Buck Main clearly demonstrate the large-scale gold, silver and zinc potential of this target. These results reinforce our belief in the value remaining to be unlocked through our ongoing exploration efforts. We look forward to receiving additional results from this stepout drill program. In addition, our team is interpreting the results of our field exploration in the Mt Morice and CR area to the west, which show tremendous potential in an underexplored area."
Buck Main drilling
The continuing drill program consists of approximately 3,500 metres over 15 drill holes, with holes designed to test for potential high-grade zones of epithermal-related gold-silver-zinc system focused on previously modelled faults and high-density vein zones (see June 8, 2023, news release), as well as the limits of mineralization to the north and west.
Holes BK23-086 and -087 were designed as infill and exploration holes to confirm the results of 1960s drilling, in addition to testing the depth extent of disseminated mineralization of the Buck Main east area to the north.
Hole BK23-086 successfully intersected moderate to strongly sericite-altered volcaniclastic rocks and hydrothermal breccias hosting 3 per cent to 5 per cent pyrite-sphalerite from 105 m to 189 m, 211 m to 236 m and 357 m to 431 m, with an increase to 10 per cent (and locally 15 per cent) pyrite-sphalerite from 189 m to 211 m. Mineralization is defined as dominantly fine disseminations and blebs, as well as hosted in local quartz-carbonate veins. The hole bottomed in volcaniclastic rocks with weak to moderate sericite alteration, hosting 0.5 per cent disseminated pyrite and trace vein-hosted sphalerite.
Hole BK23-087 intersected strongly sericite-altered volcaniclastic rocks hosting 3 per cent to 5 per cent pyrite-sphalerite from 56 m to 62.4 m and from 76.4 m to the final drilled depth of 446 metres, with intermittent quartz-felspar porphyritic and aphanitic dikes. Mineralization is dominantly fine disseminations and blebs, as well as local quartz-carbonate veins and replacements.
Both holes confirm the presence of disseminated gold-silver mineralization reported in historic holes and extends the broad zone of disseminated mineralization to the north, where it remains open for further expansion.
Prior to this program, the company had completed 84 drill holes at Buck Main for over 30,000 metres. Results to date demonstrate significant mineralization potential with district-wide size and scale opportunities. Recent drilling focused on expanding the footprint of near-surface bulk-tonnage-style mineralization, and demonstrated strong expansion potential to the west, north and south. The known mineralized footprint measures over one kilometre in strike length with mineralization open in all directions.

Quality assurance and quality control
All sample assay results have been monitored through the company's quality assurance/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 of the core was sampled and shipped by a bonded courier in sealed and secure bags to the ALS Global preparation facilities in Langley, B.C. 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. ALS Global is registered to ISO/IEC 17025:2017 accreditations for laboratory procedures.
Core samples were analyzed for 33 elements by ICP-MS (inductively coupled plasma mass spectrometry) on a 0.25-gram aliquot using a four-acid digestion (method ME-ICP61). Gold was analyzed by fire assay on a 30-gram aliquot with an AAS (atomic absorption spectroscopy) finish (method Au-AA23). Samples with more than 10 parts per million (ppm) gold were reanalyzed by fire assay using a gravimetric finish on a 30-gram aliquot. Samples with more than 100 ppm silver were reanalyzed using an ore-grade four-acid digestion and ICP-AES (inductively coupled plasma atomic emission spectroscopy) finish. Samples with more than 10,000 ppm zinc were reanalyzed using an ore-grade four-acid digestion and ICP-AES finish. In addition to ALS Global laboratory QA/QC protocols, Sun Summit implements a rigorous internal QA/QC program that includes the insertion of duplicates, standards and blanks into the sample stream.

About the Buck project
The Buck project is situated in a historic mining district near Houston, B.C., with excellent nearby infrastructure that allows for year-round, road-accessible exploration.
The project is host to the Buck Main intermediate-sulphidation epithermal-related gold-silver-zinc system. Most of the mineralization drilled to date at Buck Main consists of long, continuous zones of disseminated and breccia-hosted, bulk-tonnage-style gold-silver-zinc. Vein-hosted, high-grade mineralization has also been intersected near the centre of Buck Main.
Exploration at the Buck project is focused on investigating the lateral and vertical extent of gold-silver-zinc mineralization at the Buck Main system, and to define additional drill targets across the entire land package through systematic exploration programs.
