TORONTO, Jan. 24, 2023 /PRNewswire/ - Talisker Resources Ltd. ("Talisker" or the "Company") (TSX: TSK) (OTCQX: TSKFF) is pleased to provide the Company's first Mineral Resource Estimate ("MRE") at its 100% owned Bralorne Gold Project in Southern, British Columbia ("Bralorne Gold Project" or the "Project"). The MRE is reported in accordance with the Canadian Institute of Mining (CIM), Metallurgy and Petroleum Definition Standards (2014) incorporated by reference in National Instrument 43-101 - Standards of Disclosure for Mineral Projects, and the 2019 CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines.
- 117,000 tonnes with an average grade of 8.9 g/t Au for 33,000 ounces gold in the indicated category;
- 8.0 million tonnes at 6.3 g/t Au for 1.63 million ounces of gold in the inferred category;
- The resource is defined approximately along a strike length of 4.5 km, to a depth of 700 m and remains open along strike and at depth;
- A total of 86 veins have been identified with 63 veins open along strike and at depth, 18 remain open at depth, and 2 remain open along strike;
- Talisker believes that exploration potential exists as proximal extensions of currently defined mineralized zones, laterally and at depth, and may yield somewhere between 2.0 and 2.5 million tonnes at grades between 6.0 and 9.0 g/t Au for 400,000 – 700,000 ounces gold. This exploration potential is supported by the drill hole and channel sample data used for the 2023 MRE at drill hole spacings greater than the inferred category resources. These targets are not mineral resource estimates, potential quantity and grade is conceptual in nature. There has been insufficient exploration to define a mineral resource, and it is uncertain if further exploration will result in the exploration targets being delineated as a mineral resource.
- Regionally, mineralization has been identified to 2 km below surface, and along a strike length of 33 km.
Terry Harbort, President and CEO of Talisker, commented, "We are very happy with our inaugural MRE and that it landed solidly within our expected range. We are especially pleased to see the grade of the indicated mineral resource tracking significantly higher with increased drill hole density. With 400,000 to 700,000 ounces of drill hole constrained exploration targets defined immediately along strike from the resource and mineralization open further along strike and already confirmed to 2 kilometre depth below, we see tremendous upside and believe the Project can quickly grow to be one of the largest permitted gold deposits in western Canada." Exploration targets are not mineral resource estimates, potential quantity and grade is conceptual in nature. There has been insufficient exploration to define a mineral resource, and it is uncertain if further exploration will result in the exploration targets being delineated as a mineral resource.

- The independent and qualified persons, as defined by NI 43-101, are Carl Pelletier, P.Geo., Vincent Nadeau-Benoit, P.Geo., and Eric Lecomte, P.Eng. (InnovExplo). The effective date of the 2023 MRE is January 20, 2023;
- The mineral resources are not mineral reserves as they do not have demonstrated economic viability;
- The MRE follows the 2014 CIM Definition Standards on Mineral Resources and Reserves and the 2019 CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines;
- A total of 86 veins were modelled for the Bralorne, King, Charlotte, and Pioneer deposits. Quartz vein core wireframes were modelled with a minimum thickness of 0.50 m. A brecciated alteration halo wireframe was modelled around each quartz vein core to produce two nested wireframes with a combined minimum total true thickness of 1.2 m;
- High grade capping, supported by statistical analysis, was applied to composited data inside the high-grade quartz veins for Pioneer (1.4 m) at 100 g/t Au, Bralorne (1.4 m) at 100 g/t Au, Charlotte (1.0 m) at 31 g/t Au and King (1.2 m) at 110 g/t Au for the drill hole samples and at 400 g/t Au for the underground samples and was applied to composited data inside the brecciated alteration halo for Pioneer (1.4 m) at 6.4 g/t Au, Bralorne (1.2 m) at 9.5 g/t Au, Charlotte (1.2 m) at 5.2 g/t Au and King (1.0 m) at 7.5 g/t Au. Compositing was completed using the grade of the adjacent material when assayed, or a value of zero when not assayed;
- The mineral resources for the Bralorne Gold Project deposit were estimated using Datamine StudioTM RM 220.127.116.11 software using hard boundaries on composited assays. The ID2 method was used to interpolate a sub-blocked model (parent block size = 5 m x 5 m x 5 m);
- Indicated mineral resources were defined for blocks inside geological resource solids within 20 m of an underground chip sample (King only). Inferred mineral resources were defined for blocks inside geological resource solids within 50 m of a composite for the King and Charlotte Domains and within 60 m of a composite for the Bralorne and Pioneer Domains;
- Supported by measurements, a density ranging from 2.65 to 2.69 g/cm3 was established for the high-grade quartz vein and from 2.69 to 2.75 g/cm3 for the brecciated alteration halo. Historical underground infrastructures, underground mined volumes and a 5 m buffer around them were given a density value of 0 g/cm3.
- The reasonable prospect for an eventual economic extraction is met by having used reasonable cut-off grades for underground scenarios, a minimum mining width, and constraining volumes (Deswik shapes). The estimate is reported for a potential underground scenario at cut-off grades, depending on the mining method, of 2.65 g/t Au (Long hole stoping mining method) or 3.10 g/t (Cut and Fill mining method) and were calculated using a gold price of US$1,650 per ounce, a US$:CA$ exchange rate of 1.30, a mining cost of C$98.49/t using the long hole stoping mining method or a mining cost of C$127.49/t using the Cut and Fill mining method, transport cost of C$8.00/t, environment and G&A cost of C$24.00/t, rehabilitation cost of C$4.00/t and processing cost of C$32.00/t. The cut-off grades should be re-evaluated considering future prevailing market conditions (metal prices, exchange rate, mining cost, etc.).
- Ounce troy is metric tons multiplied by grade (g/t) and divided by the constant of 31.10348. The number of tonnes and ounces has been rounded to the nearest thousand. Any discrepancy in the totals is due to rounding effects. The rounding followed the recommendations of NI 43-101.
- The qualified persons are not aware of any problem related to the environment, permits, mining titles or related to legal, fiscal, socio-political, commercial issues or any other relevant factor not mentioned in this press release, that could have a significant impact on the 2023 MRE.
The 2023 Bralorne Gold Project MRE incorporates the Bralorne, King, Charlotte, and Pioneer Deposits. The resource is defined approximately over a strike length of 4.5 kilometres within the Bralorne Gold Project's 33-kilometre-long land package with a maximum width of approximately 750 metres, down to a maximum depth of 700 metres, with an average depth of 300 metres below surface.
The MRE for the Bralorne Gold Project is comprised of modern data collected by Talisker and validated historic data collected by previous operators. A total of 660 diamond drill holes (modern and historic), 13 modern reverse circulation drill holes, 9 modern surface channel samples and 1724 validated historic underground channel samples were used to constrain, model, and calculate the resource bodies. A strong understanding of the controls of mineralization enabled the Company's technical team to construct a MRE constrained by lithology, alteration, structure, and mineralization. The MRE is supported by a robust 3D litho-structural model of the gold-bearing orogenic vein system.
Infill and exploration drilling are ongoing on the Project. The Company believes that exploration potential exists as proximal extensions of currently defined mineralized zones, laterally and at depth, and may yield somewhere between 2.0 and 2.5 million tonnes at grades between 6.0 and 9.0 g/t gold for 400,000 – 700,000 ounces gold. This exploration potential is supported by the drill hole and channel sample data used for the 2023 MRE at drill hole spacings greater than the inferred category resources. These targets are not mineral resource estimates, potential quantity and grade is conceptual in nature. There has been insufficient exploration to define a mineral resource, and it is uncertain if further exploration will result in the exploration targets being delineated as a mineral resource.

Grade (g/t Au)
2 – 2.5
6.0 – 9.0
400,000 – 700,000
In addition, there are 23 veins with one or more conceptual targets that have been identified based on non-compliant historic data. Non-compliant data does not meet the CIM requirements for the NI 43-101 standards of disclosure and may include assays from a lab that is not ISO certified, or drill holes without downhole survey data. These conceptual targets have not yet been drill tested by Talisker.
Talisker would like to thank present and past Bralorne Gold Mines exploration staff whose hard work and dedication made this inaugural resource possible. We appreciate your efforts in helping to revitalize BC's highest grade and largest producing gold mine. We look forward to a bright future for the Bralorne Camp.

Talisker (taliskerresources.com) is a junior resource company involved in the exploration of gold projects in British Columbia, Canada. Talisker's projects include two advanced stage projects, the Bralorne Gold Complex, and the Ladner Gold Project, both advanced stage projects with significant exploration potential from historical high-grade producing gold mines, as well as its Spences Bridge Project where the Company holds ~85% of the emerging Spences Bridge Gold Belt, and several other early-stage Greenfields projects. With its properties comprising 304,931 hectares over 500 claims, three leases and 197 crown grant claims, Talisker is a dominant exploration player in south-central British Columbia.
Drill core at the Bralorne Gold Project is drilled in HQ to NQ size ranges (63.5mm and 47.6mm, respectively). Drill core samples are between 50 cm and 160 cm in length along the core axis. Samples are focused on an interval of interest, such as a vein or zone of mineralization. Shoulder samples bracket the interval of interest such that a total sampled core length of not less than 3m both above and below the interval of interest must be assigned. Sample QAQC measures of unmarked certified reference materials (CRMs), blanks, and duplicates are inserted into the sample sequence and makeup 9% of the samples submitted to the lab for holes reported in this release. ALS Global performs sample preparation and analyses in North Vancouver, British Columbia. Drill core sample preparation includes drying in an oven at a maximum temperature of 60°C, fine crushing of the sample to at least 70% passing less than 2 mm, sample splitting using a riffle splitter, and pulverizing a 250 g split to at least 85% passing 75 microns (ALS code PREP-31). Gold in diamond drill core is analyzed by fire assay and atomic absorption spectroscopy (AAS) of a 50g sample (ALS code Au-AA26), while multi-element chemistry is analyzed by 4-Acid digestion of a 0.25 g sample split with detection by inductively coupled plasma mass spectrometer (ICP-MS) for 48 elements (Ag, Al, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe, Ga, Ge, Hf, In, K, La, Li, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, Rb, Re, S, Sb, Sc, Se, Sn, Sr, Ta, Te, Th, Ti, Tl, U, V, W, Y, Zn, Zr). Gold assay technique (ALS code Au-AA26) has an upper detection limit of 100 ppm. Any sample that produces an over-limit gold value via the gold assay technique is sent for gravimetric finish (ALS method Au-GRA22) which has an upper detection limit of 10,000 ppm Au.
