- Northstar announced on November 2, 2020, that by way of a purchase agreement, the Company acquired the 1,200 ha Rosegrove Property, consisting of 19 contiguous mining claims situated immediately north and adjacent to Northstar’s 100%-owned flagship Miller Copper-Gold Property.
- Northstar’s Boston Creek area land package now totals 2,300 ha.
- The Rosegrove claims overlay the same northwest-orientated mafic and intermediate volcanic rock package that hosts significant gold-telluride mineralization at the Miller Gold Property, including evidence of syenite and porphyry intrusions. Rosegrove also appears to overlay the northern 4.5 km extension of the historic Boston Creek Copper exhalative / VMS trend.
- Rosegrove has several shear zones, faults and splays which may be related to the highly prospective First Order Catharine Fault Structure and the Pacaud and Boston Faults.
- In July, 2021 Northstar completed a UAV airborne magnetic survey at Rosegrove that identified 2 shear zones and faults that may play a key role in the control of gold mineralization.
- Five negative elliptical to ring-shaped magnetic anomalies were detected featuring magnetic signatures similar to known gold-bearing Allied and Planet Syenite alkaline intrusions on Northstar’s adjoining Miller Gold Property.
- On December 18, 2023 Northstar received notification from the Ontario Ministry of Mines of the Company’s eligibility to receive a critical minerals exploration grant of up to $80,532.50 from the Ontario Junior Exploration Program (OJEP). Grant proceeds covered 50% of Northstar’s eligible, 2023-2024 critical minerals exploration expenditures at the Rosegrove Property.
- On March 12, 2024, Northstar announced results from recently completed LiDAR and MMI (Mobile Metal Ion) soil surveys at Rosegrove Property. The primary objectives of the surveys were to substantiate exploration potential for gold and critical mineral deposits in areas with favorable geology and sparse outcrop, particularly along the Pacaud Fault Zone and northwest strike extensions of the Boston Creek Copper Trend.
- The 2021 property-wide UAV magnetic survey and more recent Rosegrove LiDAR and MMI surveys have delineated multiple coincidental magnetic, structural and soil geochemical gold anomalies (up to 17 times background) associated with the regional first-order Pacaud Fault Zone, and two distinct copper trends and zinc anomalies (up to 122 times background) in Pacaud Assemblage metavolcanics. Pacaud Assemblage rocks host the volcanogenic massive sulphide (VMS) horizons recently confirmed by Northstar’s Cam Copper Mine drill program.
- Northstar plans to ground truth these new exploration targets this coming summer by geological mapping, prospecting, sampling and trenching.
