Miller Gold Property
-
-
-
- 1100 hectare 100%-owned property located 18 km south of Agnico Eagle Mines Ltd.’s Macassa South Mine Complex.
- Alkalic intrusion-hosted gold system featuring near-surface sheeted and high-angle “Kirkland-style” gold-telluride (+/- copper) veins and porphyry-style gold-bearing sulphides in syenite and mafic volcanics.
- The Miller Gold Property is situated on a major 1st order fault structure (Catharine Fault) off the Kirkland /Cadillac-Larder Break.
- Property hosts similar age, nature, style and controls of gold mineralization as the nearby Macassa South Mine Complex.
- Demonstrable potential for a large, intrusive-hosted near-surface bulk-tonnage gold-telluride (copper) system at the Allied Gold Zone, similar in style to the Upper Beaver and Sigma / Lamaque Triangle deposits.
- Potential for significant near surface bulk-tonnage and high-grade gold resources in multiple structurally controlled zones (Vein #1, Allied, Planet, Meilleur and D zones) amenable to open pit and underground mining.
- From 2012-2015 Northstar Gold Corp completed surface exploration including ground magnetics, 3D IP surveying and 5,846 meters (27 holes) of diamond drilling Northstar (2014) / (Oban Mining Corporation – 2015).
- Northstar drill results included multiple high-grade and broad, low grade intersections with abundant visible gold and tellurides, ranging from 70-750 gold gram metres.
- In 2016 Northstar mined a 932 tonne bulk sample from the historic No. 1 Vein that averaged 5.1 g/t gold.
- Recently upgraded road access to main mineralized zones.
- Drilled 28 holes in 5,023m in 2020 at Miller and completed property-wide 3D IP, gravity and magnetic surveys.
- Drilled 22 holes in 4,485m in 2021 and completed surface stripping, mapping and sampling programs in 2021, doubling the size of the near-surface bulk tonnage Allied Gold Zone to 350m X 200m.
- Commissioned SRK Consulting (Canada) to develop tonnage and gold grade range estimations for the Allied and Vein 1 Zones in an Exploration Target Study in 2022.
- Exploration Target Study results include an upper gold range exceeding 500k oz. gold averaging 2.04 g/t Au.* Open to significant expansion with additional drilling.
- In April, 2023 Northstar reported results of a high resolution UAV airborne magnetic survey completed over the Miller Gold Property that identified a volumetrically large positive magnetic anomaly (SM-01) partially underplating the near-surface Allied Gold Zone and syenite stock. (Click here to view Northstar News Release dated April 19, 2023) The SM-01 Anomaly displays a high magnetic susceptibility signature, possibly reflecting a deeper large, discrete mafic intrusion and source area for higher, recently discovered steeply dipping Au-Cu sulphide mineralization discovered in 2021 drill holes MG21-64 (4.71 g/t Au, 0.51% Cu over 6.4m – CG1 Zone) and MG21-65 (9.41 g/t Au, 1.03% Cu over 3.0m – CG2 Zone). Eleven additional anomalies consistent with possible syenite intrusions have also been identified.
- The Miller UAV magnetic survey results are a potential game changer that indirectly supports the premise the Allied Gold Zone is the late-stage, shallow-dipping carapace of an earlier deep-seated, multi-phase gold-copper mafic intrusion-related system, similar in style to Agnico Eagle’s advanced Upper Beaver Project situated 18 km north of the Miller Gold Property.
- Alkalic gold-copper deposits such as Upper Beaver have demonstrable vertical copper-gold mineralization and grade continuity that may support both open pit and underground exploitation.
- Northstar is positioning to confirm this new Allied Gold Zone geological model and deeper gold-copper mineralization potential by diamond drilling.
*The Exploration Target estimate highlights the exploration potential of the known gold zones on the Miller Gold Property. The quantity and grades are purely conceptual in nature. Insufficient exploration has been carried out to define a mineral resource on the property. A qualified person has not done sufficient work to classify this Exploration Target estimate as current mineral resources and the Company is not treating this Exploration Target estimate as current mineral resources. These estimates must be fully verified with additional exploration work using NI43-101 reporting and CIM best practices and procedures. These values cannot and should not be relied upon and are only referred to herein as an indication of potential mineralization on the property. It remains uncertain whether a mineral resource will be delineated on the Property. Higher grade capping @ 60g/t Au in Veins – includes all domains and 150 metre extension around Vein 1.
Comparison between Miller and Agnico Eagle South Mine Complex (SMC)
- Mineralization at SMC is predominately hosted in calaverite, a gold telluride; same major gold mineral at Miller.
- Age dating and other indications has found the mineralization at Miller to be multi-stage, long-lived and associated with the Temiskaming magmatic event (2680 to 2660 Ma) contemporaneously with the age of gold deposits along the Kirkland Lake Main Break.**
- Catharine Fault Zone (Miller Property) and the Larder Break (Kirkland Lake) are both “First Order Structures”, potentially sharing a gold enriched magmatic hydrothermal reservoir at depth.
- Barry-Hollinger Shear/D-Zone (Miller Property) and the Main/’04 Breaks (Kirkland Lake) are geometrically identical and may coincide with the same deformation event.
