Benjamin Hill announces drilling program discovers porphyry style mineralization at Alotta, copper-gold-molybdenum project
This news release is not for distribution to U.S. newswire services for dissemination in the United States.
Vancouver, BC – November 28, 2023 – Benjamin Hill Mining Corp. (“Benjamin Hill” or the “Company”) (CSE: BNN – OTCQB: BNNHF – FRA: 5YZ0) is pleased to announce the completion of two inaugural diamond drill holes and the discovery of porphyry style mineralization at the Alotta copper-gold-molybdenum project in the west-central Yukon. The first two holes tested the south-central portion of an induced polarization, chargeability high with coincident copper and gold in soil anomalies. The drill program is proposed to continue in May 2024. The diamond drill and most camp equipment will remain on site over the winter. The next planned holes will focus on at least four areas of coincident copper, molybdenum and gold in soil geochemical anomalies that indicate the potential centers of porphyry mineralization.
Drill Holes ALT-23-001/002
Both holes exhibited multiple intrusive phases including intrusive breccias displaying strong biotite alteration, carbonate veining and pyrrhotite, pyrite, chalcopyrite and molybdenite mineralization as interstitial clots and stringers. The photo below is from ALT-23-001, at approximately 17-metre depth illustrates the shreddy brown biotite alteration coincident with interstitial and veinlet style mineralization. Table 1 provides the collar coordinates, orientation, and final depth for both holes.

Lorne Warner, President of Benjamin Hill Mining Corp. states: “I was on site during the drilling of both holes and observed most of the core. Disseminated and fracture-controlled mineralization in the form of pyrrhotite, pyrite, chalcopyrite and molybdenite mineralization was observed throughout both holes with total sulfide concentrations up to 5% over extensive core lengths. The exception being a quartz vein in hole ALT-23-002 with semi-massive pyrrhotite with traces of chalcopyrite. Both holes were terminated in mineralization, therefore casing was left in both holes to facilitate extending them this spring if required. When the drill program continues in May the company will focus on four large “Bull’s Eye” areas of high copper, gold and molybdenum concentrations in soil samples coincident with geophysical anomalies.”

The dashed polyline highlights the area of greatest interest for testing given the occurrence of favorable geochemical and geophysical anomalies. Figure # 1 also illustrates two proposed NQ diamond drill holes which are now completed. Proposed PDDH_001/002 are now completed as ALT-23-001/002 respectively.

Key Points about the Alotta Project:
- Similar geological setting to the Casino deposit intrusive complex. The Casino deposit as per Western Copper, June 22, 2021, news release announced a PEA outlining the deposit to host 2.17 billion tonnes of measured and indicated resources contains 7.4 billion lbs. of copper and 12.7 million ounces of gold. Insitu Gold/Copper/Molybdenum in-soil geochemical anomalies over 4.0 X 1.0 kilometers is larger than the current resource area of the Casino deposit.
- Magnetic depletion, High total potassium counts from a radiometric survey and Induced Polarization survey results coincides with anomalous geochemistry of gold/copper in soils indicating the occurrence of a large, porphyry related hydrothermal system.
- The first two drill holes both confirmed a large, multiphase, porphyry system, bearing copper and molybdenum mineralization. All split core samples will be analyzed by ALS Laboratories. Assay results are pending.
- Management of project by Archer Cathro and Associates, the same company responsible for previous Casino exploration. Archer Cathro, in consultation with Benjamin Hill geologists defined the targets for drill testing.
