|2020 Brewery Creek Mineral Resource Estimate(1)|
The Brewery Creek Project is a past producing heap leach gold mining operation with a total of about 280,000 oz Au produced from seven near-surface oxide deposits along the property's Reserve Trend from 1996 through 2002, when the mine (operated by Viceroy Resource Corporation) went into temporary closure due to low gold prices. The 200 km2 property is located 55 km due east of Dawson City, accessible by paved and gravel roads from the junction of the North Klondike and Dempster Highways.
The Project is in receipt of all necessary permits required to conduct additional exploration. The Brewery Creek Project holds a Type A Water License, subject to the restrictions and conditions contained in the Yukon Water Act and Regulations. The Project also holds a Quartz Mining License (QML).
The Company has a Socio-Economic Accord with the Tr'ondek Hwech'in with respect to the Brewery Creek Project.
Brewery Creek has NI 43-101 Indicated mineral resources of 765,000 oxide gold ounces contained in 21.14 million tonnes of material with an average grade of 1.13 g/t, and Inferred mineral resources of 440,000 oxide gold ounces contained in 14.12 million tonnes with an average grade of 0.97 g/t.
Geology and Mineralization
At the Brewery Creek Project, Tombstone Suite Cretaceous monzonite and quartz monzonite intrudes lower Paleozoic Earn Group and Road River Group stratigraphy as a series of semi-conformable sills. Cretaceous biotite monzonite and syenite stock-like bodies occur locally in the south-central part of the Project. This suite of coeval granitic rocks is known to be associated with gold mineralization at Fort Knox in Alaska and Dublin Gulch, Clear Creek and Gold Dome (Scheelite Dome) in Yukon. Intrusive rocks of a similar age host much of the mineralization at the world class Donlin Creek deposit in Alaska.
At Brewery Creek, fracture-controlled gold mineralization is hosted within porphyritic monzonite, quartz monzonite, biotite monzonite and interbedded fine-grained, siliciclastic sedimentary strata. Local replacement mineralization is also hosted within calcareous siltstones. Major ore-controlling structures in intrusive rocks are related to a post Tombstone age, NNW compressional event that produced ESE and NE striking conjugate shears and ENE listric normal faulting localized along graphitic argillite/intrusive sill contacts. Approximately 85% of the mined ore was hosted by the various Cretaceous-aged quartz monzonite sills with the balance contained in silicified and brecciated Earn Group sediments.
The Bohemian-Schooner zone represents the furthest known mineralization to the east within the Reserve Trend. A sill complex, extending for more than 1 km along an east-west orientation, hosts the majority of mineralization. Mineralization is open at depth and to the east which remains highly prospective. Exploration efforts by previous operators did not thoroughly explore east of Bohemian due to low gold prices. Golden Predator Corp. delineated the Schooner Zone extending east of Bohemian in 2011.
Big Rock Zone
The Big Rock zone, including West and East Big Rock, is the furthest known mineralization to the west and has a drill-defined strike length of approximately 1.5 km. First discovered in 1991, the initial resource definition occurred between 1994 and 1998. Golden Predator Corp. expanded this mineralization along strike, laterally and down dip including oxide mineralization at depths greater than 100 m. The Big Rock zone remains open to expansion at depth and to the southwest.
The Classic Resource area is a near surface bulk tonnage target that lies approximately 3 km south of the Reserve Trend and, together with the newly discovered Lonestar Zone, demonstrates the discovery potential of the entire southern portion of the large Brewery Creek Property. A large alklakic syenite intrusion hosts gold mineralization primarily in sheeted quartz/carbonate/pyrite+\-arsenopyrite veins and as fine-grained disseminations associated with pyrite.
Mineralization is truncated to the east by the Classic fault, and by the boundary of the intrusion to the north and south. Down dip and to the west, mineralization remains untested and open. Drilling by Golden Predator Corp. in 2012 indicates the continuation of mineralization in this direction.
Significant intercept examples:(2)
- BCRC 11-2354 with 200.0 m of 0.38 g/t gold from surface including 10.0 m of 1.10 g/t gold and 38.0 m of 0.90 g/t gold;
- BCRC 11-2348 with 148.0 m of 0.32 g/t gold from a depth of 2.0 m; and
- BCRC11-2349 with 134.0 m of 0.34 g/t gold from surface, including 22.0 m of 0.80 g/t gold
The Lonestar Zone lies approximately 5 km south of the main Reserve Trend, and confirms the potential for additional discoveries in the entire southern portion of the large Brewery Creek Project. The Lonestar zone is a target initially defined by a large gold in soil anomaly that occurs about 2.2 km southeast of the Classic zone and across the Classic fault, indicating that the Lonestar zone maybe an offset of the Classic zone. The Classic zone is on the west side of the fault and the Lonestar zone is on the east side of the fault. Drilling by Golden Predator Corp. in 2012 intersected multiple mineralization types including disseminated gold and sheeted quartz/carbonate/pyrite+\-arsenopyrite veins both hosted in syenitic intrusive stocks and sills. The 2012 drill program also discovered gold bearing calc-silicate skarn mineralization in carbonate rocks on the periphery to the syenitic intrusive.
The gold mineralization has been drilled with widely spaced holes in an area approximately 1 km by 300 m, and is open at depth and both directions along strike but is apparently cut off to the west by the northwest trending Classic fault.
Significant intercept examples:(3)
- BCRC12-2519 with 32.0 m of 0.81 g/t gold from a depth of 172.2 m;
- BCRC12-2522 with 157.0 m of 0.27 g/t gold from a depth of 44.2 m;
- BCRC12-2523 with 10.7 m of 1.14 g/t gold from a depth of 25.9 m, and 21.3 m of 2.24 g/t gold from 166.1 m;
- BCRC12-2528 with 27.4 m of 1.24 g/t gold from a depth of 1.5 m; and
- BCRC12-2529 with 93.0 m 0.27 g/t gold from the surface.
The Fosters-Canadian zone covers the Upper and Lower Fosters and Canadian deposits. The Upper Fosters and Canadian deposits have seen mining while the Lower Fosters area has not. A large sill complex extends for more than 1.2 km throughout the Fosters-Canadian zone and hosts most of the known mineralization. Existing resources remain open to expansion at depth.
North Slope Zone
The North Slope Zone lies approximately 1 km north of the Reserve Trend. The current drilled extent of the structure and sill complex at North Slope is 640 metres along strike and approximately 500 metres down dip, with mineralization intersected at up to 700 metres down dip. The mineralized sills and structural zones remain open along strike in both directions.
Significant intercept examples:
- BC11-329 with 16.0 m of 3.20 g/t gold from a depth of 41.0 m;(4) and
- RC11-2364 with 34.0 m of 1.31 g/t gold from a depth of 106.0 m.(5)
The Sleeman zone is located to the southeast of the Reserve Trend and has a known strike length of 400 m and is open along strike in both directions and at depth. Mineralization at the Sleeman zone is located in the midst of a 4 km geochemical and geophysical anomaly. This major anomaly appears to be associated with a significant structure oriented approximately 330º that intersects the Reserve Trend. The style of veining and alteration at Sleeman is similar to other resource areas, however the Sleeman deposit has higher base metals and potentially economic silver concentrations. The Sleeman deposit is also less oxidized compared to the other resource areas.
Significant intercept examples:
- BC11-361 with 40.9 m of 1.81 g/t gold and 19.7 g/t silver at a starting depth of 173.0 m;(6)
- BC11-321 with 34.4 m of 2.92 g/t gold and 19.5 g/t silver from a depth of 45.8 m;(7) and
- BC11-311 with 30.1 m of 2.21 g/t gold from a depth of 49.9 m.(7)
The claims comprising the Brewery Creek Project were initially staked in 1987 by Noranda Exploration Limited, and most of the mineralized zones that have been mined to date were identified by 1989 through detailed geochemical surveys. Since 1989 more than 200,000 meters of drilling has been completed in addition to comprehensive soil sampling and trenching programs.
In 2011, Golden Predator Corp. drilled approximately 55,000 meters resulting in the delineation of the Schooner, Sleeman and Classic deposits, as well as increasing confidence in existing resources. In 2012, Golden Predator Corp. drilled approximately 27,000 meters and discovered the Lone Star deposit, which were incorporated into the 2013 updated resource estimate. All existing resource zones remain open in one or more directions.
