Northstar resumes drilling at Miller Gold Property and reports additional results

Oct 15, 2021


Northstar Gold Corp. has announced the company has commenced a 2,400 metre, Phase IIB diamond drill program at the 100%-owned flagship Miller Gold Property, situated 18 km southeast of Kirkland Lake and Kirkland Lake Gold's Macassa SMC gold mine.

Miller Gold / Searles Property Phase IIB Drill Program

Northstar's Phase IIB drill program will focus on the following priorities:

  • 150+ metre northward expansion of the near-surface bulk tonnage gold-telluride Allied Gold Zone (north of drill hole SG21-56 (6.6 g/t Au over 117m)). 

  • Twinning select No. 1 Vein historic drill holes on the recently optioned Searles Property to corroborate all older holes to facilitate a future resource estimate. The Searles Property represents a portion of a historical resource estimate* (1987) of 0.73Mt grading 11.5 g/t Au** (for a total of 270,000 contained ounces of gold) on the No. 1 Vein of the Miller Independence Mine. The historical resource estimate straddles both the recently optioned Searles Property and Northstar's adjoining Miller Gold Property.

    * Ontario Ministry of Northern Development and Mines Assessment report # OM87-6-L-239: AFRI file 32D04SW0265 "Mining and Geological Report on the 1987 Nortek Exploration Program" by Gordon B. French, President of French & Associates Inc., Highway 112, Tarzwell, Ontario.

    **A Qualified Person has not done sufficient work to classify this historical estimate as a current mineral resource and the Company is not treating this historical estimate as a current mineral resource. The historical estimate cannot be fully verified. These values cannot and should not be relied upon and are only referred to herein as an indication of previously defined gold mineralization. In order to verify the estimate and to upgrade to NI 43-101 compliant categories, the historical area would need to be re-drilled with updated sampling procedures put in place.

  • Drill testing select 3D I.P. chargeability anomalies identified in the 2020 Dias geophysical survey. 

  • Follow up drill testing of select new 2021 surface stripping, mapping and sampling mineralized zones discoveries.

Boart Longyear mobilized a rig and crew to site in late September and have thus far completed 662m of drilling in 3 holes (MG21-63, 64 and 65 - Figure 1). Hole MG21-63 was collared 58m northeast of drill hole MG21-56 that returned 6.6 g/t Au over 117m between 14m and 131m, including 175 g/t Au over 0.6m between 14m and 14.6m, 24.9 g/t Au over 1.5m between 43m and 44.5m, and 1,170 g/t Au over 0.5m between 69.5m and 70m depth (previously released) on the west flank of the Allied Syenite. 

Phase IIB Allied Gold Zone Drilling - Preliminary Observations 

Preliminary observations from newly drilled holes MG21-63 and MG21-64 drilled northwest of drill hole MG21-56 suggest the recently discovered Independence Fault is a broad sub vertical, brittle deformation zone featuring abundant chlorite-quartz breccias with chalcopyrite mineralization and multiple occurrences of visible gold and tellurides observed over true widths of 40m to 50m within the structure (30m to 178m depth in hole 63). Drill holes MG21-63 and MG21-64 are the first holes to drill across the full width of this important structure in the Allied Syenite and the Company is currently drilling hole MG21-65. Assay results are pending.

Partial Phase IIA Drilling Results Received

Final assays for the Phase IIA drilling program are now available for drill holes MG21-55, MG21-57 and MG21-59. Final assays remain to be received for the bottom portion of drill hole MG21-56, drill holes MG21-58, MG21-60, MG21-61 and MG21-62. The Company has been informed by the assay laboratory that receipt of these final assay results is imminent. 

Drill hole MG21-55 was designed to test the area south of previous drill hole MG20-47 (1.2 g/t Au over 107.3m between 4.7m and 112m) along the western flank of the Allied Syenite. Unfortunately drill hole MG21-55 deflected away from the syenite contact near surface and penetrated the syenite at 125m depth, well below the Allied Syenite Gold Zone horizon. Hole SG21-57 was collared 400m northeast of the Allied Syenite and targeted a GoldSpot AI anomaly reflecting known gold-in-syenite features, which unfortunately turned out to be a clay altered gabbro intrusion. Drill hole SG21-59 (Figure 2) intersected the Vein 1 Zone 30m north of drill hole MG20-46 (15.35 g/t Au over 2m from 56m to 58m) and returned 1.5 g/t Au over 2.75m from 70m to 72.75m including 3.74 g/t Au over 0.75m from 72m to 72.75m (see Table 1). Planned drill holes S21-01 to S21-04 will twin historic resource Vein 1 holes on the Searles Property within the Allied Deformation Zone for resource confirmation purposes. 

Surface Exploration Program Update

An extensive mechanical surface stripping program is now complete on the Miller and Searles Properties. Hundreds of channel samples have been collected to date with channel sampling ongoing. New discoveries have been made in Areas C2, E and D2 as shown in Figure 2 and the Company's website corporate presentation. Stripping in Area C2 uncovered the possible southeastern extension of the porphyry zone drilled in hole MG20-49 (1.43 g/t Au over 118.5m including 7.96 g/t Au over 15m) characterized by abundant shallow dipping quartz veins with pyrite halos cutting feldspar porphyry and the surrounding mafic volcanics. Stripping in Area E, located 450m west of the Allied Syenite exposed a broad northwest striking shear zone at least 30m wide and open along strike to the southeast. The zone contains abundant stockwork style quartz veins, pervasive Fe-carbonate alteration, with 5-8% pyrite and chalcopyrite mineralization. The Vein 1 Zonehas been exposed for 350m along strike to the east of the Searles Property boundary with a significant discovery being made in Area D2 where the zone blows out to 6m in true width with 8-15% pyrite mineralization. Surface grab and channel samples have been submitted to ALS Laboratories for analysis; results are forthcoming and will be reported with additional details when received.
