Positive Underground Drilling Results At Copperstone Gold Project

VANCOUVER - Sabre Gold Mines Corp. announced positive underground drilling results at the Copperstone gold project located in Arizona, United States.

Mike Maslowski, Vice President of Technical Services and Exploration, said, “The initial assay results from our in-fill drill program, designed to provide detailed geologic information for final stope planning and design have been received. Drill results are showing very good continuity of the mineralized shear zone and gold grades while adding further confidence to our resource model and detailed mine plan.”

The underground core and reverse circulation (RC) drill programs, conducted in two phases is now completed with further assays pending. Core drilling was conducted in 2021 and previously reported. The RC drilling was conducted during the period October to December with partial assays results having been received. The RC program consisted of 85 holes for a total of 3,004 meters. The core and RC drilling targeted both the C and D Zones where the initial mining at Copperstone is scheduled to commence. Drill holes were designed to drill sections of the planned mining areas at close spacings of approximately 6.5 meters along strike and dip to provide detailed data on grade and thickness distributions. A portion of the program also included holes testing local downdip projections and local strike projections.

The RC drilling program included in-filling a large gap on the northeast down dip projection of the D Zone. Two previous holes, drilled in 2019 and spring 2021, intercepted the shear zone at low angles and encountered elevated gold grades about 40 meters down dip of where the recent drilling was targeted. Assays have been received from drill holes P2D84 and P2D46, which intercepted 12.2 m at 8.0 g/t and 4.6 m at 5.7 g/t respectively. These holes are confirming the continuity of mineralization along dip near the northeastern drilled limits of the D Zone. The current underground drill platforms in this area are at their limit to further test the down dip limits but once drill platforms can be established additional drilling will be conducted to further define the down dip extent of this zone.

Partial results have been received on two other drill fans on the D Zone located more central to the zone, Station B and Station C. The results show the drill holes are intercepting the projected shear zones near the modeled locations and are showing good structural continuity along the dip and extending the zone down dip. The assay results are confirming model gold grades and are defining grade distributions to provide details for detailed stope design and mine planning.

Sabre is encouraged by the initial assay results from this latest round of drilling. Overall drill results from this latest round of RC drilling are correlating with the previous core drilling assays which will help confirm ore delineation and ore control methodology.
