SCOTTIE RESOURCES REPORTS POSITIVE INITIAL METALLURGICAL TEST RESULTS FOR BLUEBERRY ZONE WITH UP TO 97.6% GOLD RECOVERY
Scottie Resources Corp. has released positive preliminary metallurgical test results for the Blueberry zone, part of its 100-per-cent-owned and royalty-free Scottie gold mine project located 35 kilometres north of the town of Stewart, B.C., along the Granduc Road. The program was completed by independent metallurgical consultants Sepro Laboratories at their testing facilities in Langley, B.C.
Metallurgical program details
A composite sample was created from coarse reject material from 2022 drill core samples. Sample selection was based on geological considerations, distribution throughout the mineralized structure, and geochemical and mineralogical data to best represent a conceptual resource. Core samples were shipped for metallurgical testing to Sepro Laboratories, an accredited facility located in Langley, B.C.
President and chief executive officer Brad Rourke comments: "One of the primary roles of junior explorers is to reduce risk by answering unresolved questions. These promising initial metallurgical results illustrate strong gold recoveries using multiple extraction techniques and by doing so substantially derisk the project. With so many advantages to the deposit -- high grade, near surface, on a road, adjacent to high-voltage power -- these results confirming the deposit's metallurgy adds yet another positive element."
Discussion of results
After homogenization of the samples, representative head grade samples were taken from the composite sample. The average gold grade of these representative samples was in excellent agreement with the calculated grade based on a weighted average of the combined drill intercepts, 11.8 grams per tonne versus 11.9 g/t, respectively. The average silver grades varied slightly with respective values of 9.6 g/t and 6.5 g/t.
The recovery processes used to test the samples were selected based on technology and flowsheets of nearby operating mills, the test work focused on recovery processes such as gravity recoverable gold (GRG), rougher flotation (RF), and cyanide leaching (CN). Grind sizes tested were between p80s of 103 mum and 25 mum. The results were not fully optimized during this preliminary testing program, but to serve as a baseline from which to evaluate the processing of ore from the Blueberry deposit.
Cyanide leach testing
Direct CN leach test results show that 97.6 per cent of the gold can be extracted with a grind size of p80 of 25 mum. Cyanide and lime consumptions were low at 1.2 kilograms/t-solids and 0.91 kg/t-solids, respectively.
CN leach tests on the coarser GRG tails (milled to p80 of 103 mum) returned 91.1-per-cent gold recovery (72.4 per cent silver); cyanide and lime consumptions were low at 0.65 kg/t-solids and 0.72 kg/t-solids, respectively.
Gravity-rougher flotation testing
The standard GRG test resulted in a GRG value of 37.6 per cent by grinding of the material to a p80 of 103 mum. Using a grind size of p80 of 55 mum on the GRG, the overall gold gravity-rougher flotation recovery was 87.2 per cent with a grade of 42.1 g/t Au in 19.7-per-cent mass. The total silver recovery of 88.6 per cent with a grade of 31.9 g/t Ag was achieved in the same test.
About the Blueberry contact zone
The Blueberry zone is located just two kilometres northeast of the 100-per-cent-owned, past-producing Scottie gold mine located in British Columbia, Canada's Golden Triangle region. Historic trenching and channel sampling of the Blueberry vein include results of 103.94 g/t gold over 1.43 metres, and 203.75 g/t gold over 1.90 metres. Despite high-grade surficial samples and easy road access, the Blueberry vein had only limited reported drilling prior to the company's exploration work. The target was significantly advanced during Scottie's 2019 drill program when an interval grading 7.44 g/t gold over 34.78 metres was intersected in a new splay-off zone of the main Blueberry vein. The drill results received from 2020 to 2023, coupled with surficial mapping and sampling, suggest that this splay is in fact a major north-south mineralized structure, of which the Blueberry vein was only a secondary structure. The zone is steeply dipping, and there is no current restraint on its potential depth; the mineralization at the adjacent Scottie gold mine has a vertical extent greater than 450 metres. The Blueberry zone is located on the Granduc Road, 20 kilometres north of Ascot Resources' Premier project, which is fully financed for construction (Dec. 12, 2022). Newcrest's Brucejack mine is located 25 kilometres to the north.
These exceptional results support Scottie's pathway to a multimillion-ounce deposit, which it will continue to uncover during the 2023 exploration season.
Dr. Thomas Mumford, PGeo, a qualified person under National Instrument 43-101, has reviewed the technical information contained in this news release on behalf of the company.
Quality assurance and quality control
Results from samples taken during the 2022 field season were analyzed at SGS Minerals in Burnaby, B.C. The sampling program was undertaken under the direction of Dr. Mumford. A secure chain of custody is maintained in transporting and storing of all samples. Gold was assayed using a fire assay with atomic absorption spectrometry and gravimetric finish when required (over nine g/t gold). Analysis by four-acid digestion with multielement inductively coupled plasma atomic emission spectroscopy analysis was conducted on all samples with silver and base metal overlimits being reanalyzed by emission spectrometry.
About Scottie Resources Corp.
Scottie owns a 100-per-cent interest in the Scottie gold mine property which includes the Blueberry zone and the high-grade, past-producing Scottie gold mine. Scottie also owns 100-per-cent interest in the Georgia Project which contains the high-grade, past-producing Georgia River mine, as well as the Cambria project properties and the Sulu property. Altogether Scottie Resources holds approximately 60,000 hectares of mineral claims in the Stewart mining camp in the Golden Triangle.
The company's focus is on expanding the known mineralization around the past-producing mines while advancing near-mine high-grade gold targets, with the purpose of delivering a potential resource.
All of the company's properties are located in the area known as the Golden Triangle of British Columbia which is among the world's most prolific mineralized districts.
