Ivanhoe Electric Identifies a new Porphyry Copper-Gold-Molybdenum System in the Battle Butte Area Associated with a Typhoon™-identified Anomaly
VANCOUVER, British Columbia, Jan. 07, 2025 (GLOBE NEWSWIRE) -- Brixton Metals Corporation (TSX-V: BBB, OTCQB: BBBXF) (the “Company” or “Brixton”) is pleased to announce exploration results provided by operator Ivanhoe Electric Inc. (“Ivanhoe Electric”) (NYSE American: IE; TSX: IE), on the Hog Heaven Project. The road-accessible project is located in Flathead County, 50 miles southwest of the town of Kalispell, northwestern Montana, USA. Highlights below are sourced and further defined by Ivanhoe Electric’s press release dated January 6, 2025.
Highlights
Exploration drilling at the Hog Heaven Project in Montana included approximately 14,000 meters in eleven drill holes (Figure 1).
Exploration drilling in the Battle Butte Area at the Hog Heaven Project intersected a porphyry copper-gold-molybdenum system within a large, deep Typhoon™-identified anomaly.
Exploration drilling in the Flathead Mine area included drill holes HHD-012 through to HHD-016, which intersected broad intervals of epithermal-type low-grade precious metals-bearing polymetallic sulphide mineralization hosted in veins, breccia matrix fill, and disseminations.
Ivanhoe Electric has leased a further 4,925 acres of private surface and mineral rights from a private owner, consolidating the district and providing additional access to areas prospective for porphyry systems.
Chairman and Chief Executive Officer, Gary R. Thompson, stated, “Drilling at the Hog Heaven Project continues to deliver highly encouraging copper-gold results. The multiple phases of porphyry at the Battle Butte Area are typical in these types of mineralizing systems and key next steps would be to isolate the high-grade copper-gold porphyry phase.”
Initial drilling at the Battle Butte Area, HHD-017 through to HHD-022, has intersected a porphyry copper-gold-molybdenum system (“Battle Butte Porphyry”) associated with a large, 1,500 meters by 1,000 meters Typhoon™ conductivity anomaly at 1,200 meters depth (Figure 2). Mineralization is related to a series of variably mineralized and altered porphyry intrusives and hydrothermal breccias hosting gold-bearing copper, iron, and molybdenum sulphides as breccia matrix, sheeted to stockwork veining and as disseminations.
Hole HHD-018: returned 286.0m of 0.14% copper, 0.14 g/t gold, 0.01% molybdenum, and 1.70 g/t of silver from 947.0m depth.
Including 97.9m of 0.21% copper, 0.20 g/t gold, 0.01% molybdenum and 2.79 g/t silver from 947.0m.
Hole HHD-019 returned 680.0m of 0.09% copper, 0.06 g/t gold, 0.02% molybdenum, and 0.96 g/t silver from 1,172.0m depth.
Five drill holes intersecting the Battle Butte Porphyry demonstrate a porphyry system believed to be starting at approximately 900 meters depth, with a vertical thickness of 800 meters, at least 600 meters by 400 meters in lateral dimension, and open to the east and northeast. Initial assay results show broad intervals of low-grade mineralization with a gold-to-copper ratio near one-to-one. Narrower but higher-grade sub-intervals are associated with the presence of the higher-grade copper sulphide mineral bornite (approximately 63% copper by weight), where the gold-to-copper ratio starts to increase.
Current evidence suggests that the Battle Butte Porphyry system is open to the east and north, where the Typhoon™ anomaly remains untested at depth. Exploration in 2025 will continue to test the Battle Butte Porphyry, searching for higher-grade copper-gold zones and the presence of additional porphyry centers across the project.

Flat recoveries of 100% were used for metal equivalency calculations.
Intervals were derived on a CuEq basis with a cutoff of 0.1% CuEq.
Maximum internal dilution of 5 meters was applied.
Copper assays were capped at 10% for interval calculations.

Quality Assurance and Quality control
Ivanhoe Electric employs industry standard QA/QC and data verification protocols. The diamond drill holes were completed using PQ and HQ diameters. The drill core was cut lengthwise into halves using a diamond-bladed saw, with one-half used for the assay sample and the other half retained in core boxes and archived at site. Pulps and rejects are also stored on site for archival purposes. Mineralized zones were generally sampled at 2m intervals. Each core sample was placed into a bag with a unique numbered sample identification tag. Quality control samples were inserted between core samples using the same numbering sequence. Then samples were grouped into batches for shipping and laboratory submissions. Chain of custody records are maintained for sample shipments and the custody is transferred from Ivanhoe Electric expeditor to the laboratory upon delivery.
Samples were shipped to ALS Laboratories in Twin Falls, Idaho, for sample preparation and analysis. Samples were analyzed using customary four acid digestion and ICP-MS finish. A standard gold fire assay package was used to analyze gold. Silver content was assessed using either HCl leach and ICP-AES finish or fire assay with gravimetric finish depending on silver concentrations. ALS Minerals Twin Falls is an independent laboratory certified under ISO 9001:2008 and accredited under ISO/IEC 17025:2005 by the Standards Council of Canada.
The Hog Heaven copper-silver-gold project is an advanced-stage exploration project, which historically produced high-grade silver, gold, and copper. Between 1913 and 1975, Anaconda Copper Mining and lessees produced 6.7Moz Ag, 3,000 oz Au, 23M lbs of lead, and 0.6M lbs copper from 0.23Mt of direct-ship ore, grading 29 opt silver. The road-accessible property is located in Flathead County, 50 miles southwest of the town of Kalispell, northwestern Montana, USA.
Ivanhoe Electric and Brixton entered into an earn-in agreement in 2021. Under the earn-in agreement, Ivanhoe Electric may earn up to a 75% interest in the Hog Heaven Project by making cash payments totaling USD$4.5 million ($2.5 million paid to date) and incurring an aggregate of USD$40 million in exploration expenditures by 2032.
