Cassiar Gold Corp. announce assay results from an additional eight diamond drill holes from its recently completed 2023 exploration program. The results reported here are from the Main Mine and Bain targets located in the Cassiar South area of the Company’s flagship Cassiar Gold Property in northern British Columbia. The 2023 Cassiar South drilling program is part of a continuing effort to further explore for a) new parallel veins associated with the high-grade, historically producing mines at Cassiar South, and b) fault offsets of past producing vein systems. Results remain pending for 21 drill holes totaling 7,588 metres (m) of drilling from the 2023 program.
The latest drilling results reported in this news release are from eight holes totaling 3,200 m from the Cassiar South project area (Figure 1), which were drilled near the historically producing Main Mine and Bain-Cusac areas (see results in Table 1).
- Drill hole 23MM-004 at the Main Mine area intersected a broad mineralized intercept which supports the interpretation of a more extensive mineralizing system than previously identified by the 2022 drill program, returning long intervals of mineralization including:
- 237.6 m of 0.67 g/t Au from 139.2 m downhole, including 8.3 m of 2.39 g/t Au with 1.4 m of 5.93 g/t Au, extending mineralization to vertical depths 150 m beyond the extent of intercepts identified in 2022 drill holes.
- Drill hole 23WB-204 near West Bain encountered veining and mineralization 120 m east of historical drilling and coincident with a VLF anomaly that occurs to the north and parallel to the Bain vein system.
- All holes drilled at Cassiar South intersected gold-bearing quartz veins across target areas reported in this news release.
“Our 2023 program at Cassiar South encountered gold mineralization in all drill holes and we are pleased to have expanded mineralization at the Main and Bain vein systems with these most recent results, which suggest the potential for broader, bulk areas of mineralization than historically encountered at Cassiar South,” stated Marco Roque, CEO of Cassiar Gold Corp. “The Cassiar South vein systems lie within an expansive permitted mine area with potential for continued growth and discovery and we look forward to advancing exploration efforts here in future programs.”

Cassiar South Project Area
The Cassiar South project area of the Cassiar Gold Property hosts numerous shear vein targets and several past-producing underground mines including the Bain, Cusac, Vollaug and Main Mines, which have historically produced over 315,000 ounces of gold grading between 10 to 20 g/t Au. The past producing high-grade Vollaug vein is known to have a strike length of up to 3 km.
Veins at Cassiar South are classic, orogenic-style, high-grade gold bearing quartz veins with free gold. They occur in mafic volcanic rocks stacked between low-angle listwanite-bearing thrust surfaces and lenses of fine-grained clastic sediments. Vein sets occur in multiple mafic volcanic units, and there is potential to define: (1) stacked veins below known veins in mafic volcanic units of underlying thrust panels; (2) parallel vein sets beneath overlying sedimentary and listwanite units within thrust panels; (3) extensions of known vein systems.
Drilling at Cassiar South encountered gold-bearing quartz veins in altered mafic volcanics in all eight holes, which continues to reinforce the potential for ongoing expansion of known mineralization and potential to identify new mineralized areas along prospective structural corridors in this project area.
2023 Drilling at the Main Mine target area
The Main Mine vein system historically produced 150,000 ounces of gold at an average grade of 17.14 g/t Au intermittently from 1979 to 20071. In 2022, the Company drilled three holes at the Main Mine area to evaluate the potential for: (1) parallel shear vein sets to occur near the historical mine, and (2) down dip extensions of past-producing vein segments. Four drill holes which are reported here, totaling 1,556 m in cumulative length, aimed to expand mineralization identified in 2022 which occurred 260 m northwest of previously mined vein segments at the Main Mine area (Figure 1), as well as test for potential new veins parallel to the past-producing Rory vein at Main Mine.
All four drill holes reported here successfully intersected gold-bearing quartz veins at the Main Mine target area. The 2023 drill campaign extended recently identified gold mineralization associated with extensive strong alteration and minor quartz veining 180 m beyond mine infrastructure and confirmed the down dip extension of mineralization associated with the Main Mine system.
Drill holes 23MM-004, 23MM-006, 23MM-007, and 23MM-005
Drill holes 23MM-004, 23MM-006, and 23MM-007 (Table 1; Figure 1, 2, 3) are southeast-oriented holes designed to test for potential parallel vein sets north and west of Main Mine infrastructure as follow up to mineralized intercepts encountered during the 2022 drill program, which intersected extensive quartz veining, alteration, and gold mineralization in an area where veining had not previously been identified (see NEWS RELEASE, April 20, 2023).
Drill hole 23MM-004 encountered extensive graphite-dolomite-quartz altered and sulphide-mineralized basalt. Assays returned broad low-grade intercepts (Table 1, Figure 2, 3, 4) with more discrete higher grades intervals within the mineralized zone surrounding a broad carbonaceous fault zone with minor quartz veins and disseminated pyrite mineralization in previously untested areas >180 m beyond the underground workings. Results include:
- 237.6 m of 0.69 g/t Au from 139.2 m down hole, including 8.3 m of 2.39 g/t Au, with 1.4 m 5.93 g/t Au, extending mineralization 65 m to the northeast and to vertical depths 150 m beyond extent of intercepts identified in 2022 drill holes (NEWS RELEASE, April 20, 2023)
- See Table 1 for additional results
Drill holes 23MM-006 and 23MM-007 encountered gold bearing quartz veins in strongly altered basalt and returned multi-metre mineralized intercepts above 0.5 g/t Au. See Table 1 for additional results.
Drill hole 23MM-005 (southeast directed) is a 200 m southwest step out drill hole that was designed to test for an interpreted extension of mineralization identified by the 2022 program. This drill hole was also planned to evaluate the potential for additional shallow vein systems parallel to past producing vein segments of the Main Mine system, up to 200 m north of historical surface drill holes (Figure 4). This drill hole intersected the potential down dip extension of the Rory vein of the Main Mine, 95 m beyond the extent of the current vein model (Table 1, Figure 4).
2023 Drilling at the Bain vein system
The central Bain vein system historically produced 24,000 ounces of gold at an average grade of 13.71 g/t Au from 1993 to 19951. Historical drilling by a previous operator in 1990-91, 2002, 2008 and 2009 in unmined areas demonstrated the eastern continuation of the vein system forming a 2 km long corridor of known high-grade gold mineralization. The area was subject to additional mine development in 2009 to within 30 m of the unmined East Bain area, allowing for ease of potential future underground access.
Four drill holes which are reported here, totaling 1,644 m in cumulative length, were drilled at the East Bain Extension target and West Bain areas of the past-producing Bain vein system (Figure 1, 5). This drilling was designed to test for lateral and downdip extensions of known mineralization, potential parallel vein sets at the East Bain Extension and West Bain areas, as well as identify potential offset segments of the past-producing vein system at East Bain Extension.
All four drill holes intersected significant gold-bearing quartz veins in the east and west Bain areas. These intercepts expanded mineralization along the Table Mountain thrust fault at the east and identified veining and mineralization in an untested area between historical vein prospects at the western extent of the target area. The Bain system mineralization holds potential for continued lateral expansion as well as extension at depth.
East Bain Extension
Mineralization encountered along the East Bain Extension occurs within an unmined mineralized trend greater than 540 m in strike length below and eastward from existing underground development. Drilling from the 2022 exploration program confirmed continuity of the auriferous Bain shear vein structure as a highly prospective exploration corridor for further follow up in 2023.
Three drill holes (south oriented), totaling 1,312 m completed at East Bain Extension were designed to follow up on mineralization encountered in drill hole 22EBX-103 during the 2022 drill campaign which returned 14.6 m of 2.21g/t Au, including 4.0 m of 5.05 g/t Au, as well as 2.2 m of 32.95 g/t Au, including 0.6 m of 123.50 g/t Au (see NEWS RELEASE, April 4, 2023).
Drill holes 23EBX-107 and 23EBX-108 confirmed the extension of veining and gold mineralization along the Table Mountain thrust fault contact south and north of drill hole 22EBX-103, while drill hole 23EBX-109 tested the interpreted orientation of a high-grade mineralized intercept in 22EBX-103 as a 240 m step out to the northeast.
- Drill hole 23EBX-107 returned 16.6 m of 0.61 g/t Au from 168.3 m downhole, including 4.9 m of 1.14 g/t Au and 1.0 m of 1.13 g/t Au, expanding mineralization 20 m to the south along the Table Mountain thrust contact.
- Drill hole 23EBX-108 identified the extension of mineralization along the Table Mountain thrust fault, 65 m north of 22EBX-103.
- Veining and mineralization encountered in 23EBX-109 supports the interpreted orientation of mineralized veining encountered in 22EBX-103.
- See Table 1, Figure 5 for additional results.
One drill hole (23WB-204), totaling 332 m, was designed to test for additional veins parallel to the western extent of the Bain system, 120 m east, and over 200 m southwest of historical drilling. This target area coincides with a very low frequency (VLF) electromagnetic anomaly that exhibits a similar signature to anomalies coincident with select past-producing vein segments at Table Mountain. The drill hole confirmed the presence of veining and mineralization in this previously untested area, encountering multiple intervals of gold-bearing quartz veins with varying degrees of dolomite-sericite alteration and minor sulphide mineralization. 23WB-204 returned (Table 1, Figure 5):
- 1.8 m of 3.49 g/t Au from 23.6 m downhole, including 1.0 m of 5.58 g/t Au,
- 1.0 m of 2.45 g/t Au from 128.2 m down hole, and
- 0.5 m of 2.67 g/t Au from 133.2 m down hole
The results of drilling reported from Cassiar South in 2023, coupled with the Company’s previous drill campaigns, continue to demonstrate the potential for further expansion of past-producing vein systems and encountering previously untested gold-bearing veins on the property, highlighting the importance of advancing exploration in these areas.
