Northstar Gold Corp. (CSE:NSG, OTCQB:NSGCF) (“Northstar” or the “Company”), announces the completion of a surface exploration program and high resolution airborne magnetic survey over the Company’s 100%-owned, 615 hectare Milestone Property , situated 3 km southwest of the town of Temagami, Ontario.
Highlights
72 surface samples collected over a 1.5 km strike length
80-line km, high resolution UAV magnetic survey completed
2022 Surface Exploration Program
Northstar carried out a brief surface exploration program consisting of prospecting and sampling of the key metagabbro trend on the Milestone Property between November 9th and 16th, 2022. A total of 72 surface samples were collected over a 1.5 km strike length of the lower metagabbro contact and include samples with massive pyrite +/- chalcopyrite mineralization collected both in-situ and from historic muck piles. Assay results are pending.
2022 High Resolution UAV Magnetic Survey
An 80-line km, high resolution UAV magnetic survey was conducted by Quebec based Vision4K on the Milestone Propertyf on November 8th, 2022, utilizing a stabilized MAG-drone survey system equipped with a Scintrex Cs-VL Cesium Vapor magnetometer and collision avoidance sensors. The high-resolution magnetic data will be combined with recent LiDAR survey data, assay data and historic mapping information to assist Northstar in modeling the lower metagabbro contact, identifying prospective anomalies within the contact zone and cross cutting structures potentially hosting massive copper sulphide mineralization in the footwall of the sulphide zone within the host rhyolite. A UAV magnetic survey report detailing results is expected before year-end.
Management Commentary
“We are pleased to have completed this timely, integrated surface exploration program at Milestone,” stated CEO Brian Fowler. “Data compilation and integration will identify key areas of copper sulfide mineralization and provide Northstar important information to advance the property. While the Miller Gold Project remains our flagship property, we are excited to further qualify the exploration potential at Milestone in the coming year.”
Milestone Property Overview
The Milestone Cu-Co-Ni Property was originally acquired by Northstar in 2010 and enlarged by additional claim staking in 2012 and 2021.
Significant near surface massive to semi-massive sulphides (pyrite, chalcopyrite, pyrrhotite, millerite), magnetite and cobalt-nickel sulfarsenides associated with the basal contact between a 250m thick metagabbro sill and a chloritized rhyolite metavolcanic unit have been discovered on the Milestone Property over a strike length of 1.0 km and a true width that varies from 5m to 30m.
Milestone exhibits similar geology, mineralization, stratigraphic setting and alteration as Teck Resources former high-grade Temagami copper mine located 20 km southwest along strike. The Temagami Mine produced approximately 900,000 Tons at an average grade of 6.0% Cu during the period 1955 to 1972. (1) Both the Milestone Property and Temagami Mine share some similarities with the “footwall breccia” type ore deposits found in the Sudbury basin.
