Commander completes surveys over Burn, finds targets

COMMANDER IDENTIFIES TARGETS AT BURN PORPHYRY COPPER PROPERTY, BRITISH COLUMBIA

Commander Resources Ltd. has released the results of a property-wide airborne magnetic survey and an induced polarization survey (IP) at its 100-per-cent-owned Burn copper and gold porphyry project located 100 kilometres (km) north of Smithers, B.C.

Highlights:

  • 170-square-kilometre (km) property in the Babine copper belt of northern B.C. preliminary drilling has identified a gold-rich zone (83.5 metres (m) at 1.08 grams per tonne (g/t) gold (Au) in hole B-2) and separate upper-level porphyry copper-gold zone (50 m at 0.24 copper equivalent (CuEq) per cent in hole B-01);
  • 1,875 line km of helicopter high resolution Heli-GT magnetic survey at 100-metre line-spacing completed covering the majority of the property;
  • 18 line km of IP survey over the core Charleston target;
  • Large three-kilometre-by-two-kilometre chargeability anomaly outlined that is open to the south;
  • Drill targets outlined and supported include stepout drilling from existing discovery holes and larger untested areas of combined high chargeability with high magnetic responses.

Robert Cameron, president and chief executive officer, states: "The Burn project is a grassroots porphyry discovery by Commander that had early drill success on its first target tested. The current geophysical program was designed to provide guidance to put current drilling in context and to plan continued follow-up exploration. The large six-square-kilometre IP anomaly on the Charleston target, a key hallmark of porphyry copper deposits, has outlined extensive elevated chargeability regions outside of the current drilled areas and at depth and require drill follow-up. Charleston is only one of five targets within the larger property boundary."

Geophysical surveys

The company has completed a property-wide detailed geophysical airborne magnetic survey over the entire property using a Heli-GT system at a 100-metre line spacing. Previous surveys were conducted with a single sensor at a 200-metre line spacing. The Heli-GT system is a magnetic gradiometer system in a towed bird that provides measured vertical and horizontal gradient and is higher resolution and lower noise than the previous survey that was flown. Results from the survey show linear features interpreted as faults such as the newly recognized northwest structure that separates the gold zone intercepted in hole B-2 from the copper zone identified to the east. Furthermore, peak magnetic responses, in one case associated with a quartz-magnetite stockwork have shifted slightly as a result of the closer line spacing. These new data will allow more accurate modelling of magnetic targets, as well as providing an improved framework for interpreting the recent drilling.

The company also completed an 18-line-kilometre induced polarization (IP) survey over the primary Charleston target. This dataset is a key component of the porphyry copper exploration toolbox and has not been previously collected except from a single test line completed north of the current drill plan. This new survey has outlined a large three-kilometre-by-two-kilometre chargeability anomaly that is open to the south. Peak values within the survey area exceeded 50 millivolts per volt (Mv/V). The majority of this anomaly remains untested.

Preliminary inversions and modeling of this data are under way and have indicated several regions of priority follow-up. Drill targets outlined include continued stepout drilling from existing discovery holes and larger untested areas of combined high chargeability with high magnetic responses.

About the Burn property

The Burn property, which covers 17,675 hectares (ha) was initially acquired directly by Commander in 2018 to cover prominent gossans exposed along ridges. It is located within the Babine porphyry belt 70 kilometres (km) north of two past producing mines at Bell and Granisle. Initial work at Burn in 2018 identified widespread phyllic-style alteration with trace amounts of chalcopyrite. There were no previous geophysical surveys or drilling. Past work by Commander, funded by Freeport, included a property-wide airborne magnetic survey which outlined two prominent circular magnetic rings and several linear magnetic highs that coincide with stocks and dikes of Eocene age. A property-wide sampling program of stream sediment sampling, soil and rock sampling, and geological mapping has identified five alteration zones of which the largest is referred to as the Charleston zone. Geology is dominated by numerous phases of biotite feldspar hornblende (BFP) porphyry dikes and stocks exhibiting alteration from chlorite and epidote to chlorite-magnetite and moderate quartz-sericite-pyrite (phyllic) to intense phyllic with local quartz veinlets and stockworks in the central copper-rich zone and surrounded by alteration dominated by intense phyllic alteration with iron carbonate and elevated zinc that intrude hornfels and intensely altered sediments. First pass drilling in 2022 and 2023 (14 holes, 5,916 metres) identified two discrete zones referred to as the west gold zone and the central copper-gold zone. Key drill results are tabulated in the attached table.

The Burn project is 100 per cent owned except for an internal parcel of 127 hectares in which the company has the right to earn a 100-per-cent interest. Freeport-McMoRan Mineral Properties Canada Inc. holds a 2-per-cent net smelter return royalty (NSR) over the majority of the property and a 1-per-cent NSR over two mineral claims totaling 127 hectares optioned from a third party. The 2-per-cent NSR may be reduced to 1 per cent for a payment of $5-million (U.S.). The internal claim will have an additional 2-per-cent net smelter return royalty with a buydown provision to 1 per cent for $1-million and with a further buydown provision of the remaining 1 per cent for $5-million.

QA/QC (quality assurance/quality control) and data verification

Commander's 2022 and 2023 exploration program was supervised by Stephen Wetherup, PGeo, Commander's vice-president of exploration. The drill contractor was ITL Drilling of Smithers, B.C. Half-core NQ (47.6 millimetres (mm)) sawed samples from continuous intervals throughout the reported drill holes were sealed on site and shipped to Bureau Veritas (BV) labs in Vancouver, B.C. where fire assay and multielement analyses were completed. Drill core was crushed, pulverized and analyzed for 48 elements using a four-acid dissolution followed by ICP-MS (MA250) with a 30-gram sample analyzed for gold by fire assay and fusion Au by ICP-ES (FA330-Au) with overlimit gold analyzed by lead collection fire assay 30-gram fusion with gravimetric finish (FA530). Blanks and commercially certified reference materials were inserted blind into the sample stream with an overall insertion rate of 10 per cent. Field duplicates representing a quarter core split of the original sample are inserted at 2.5 per cent. In addition, pulp and crush duplicates are inserted by the laboratory. The QA/QC results were reviewed and the QA/QC results for the reported drill holes are acceptable. Results were previously discussed with accompanying QA/QC statements in press releases on Nov. 13, 2020, Oct. 6, 2022, March 6, 2023, and Jan. 19, 2024.
