Honey Badger Silver Inc. (TSX-V: TUF) is pleased to announce initial results from its newly-acquired, 100%-owned, 5,690 hectare Plata Silver Property located in east-central Yukon. Silver, lead and zinc assays from five composite grab samples of hand sorted material collected from 90 ore bags left behind by historic miners at Plata are listed below:
These preliminary results confirm the potential for very high-grade silver mineralization at Plata. Gold assays for these five composite samples are pending as are assay results from rock and channel samples collected during Honey Badger’s Phase 1 Summer Work Program at Plata.
The Plata Silver Property lies within the Tintina Gold Belt and displays numerous similarities to the world-class Keno Hill Mining Camp, Canada’s second largest primary producer of silver, located 165 km west of the Plata Silver Property. Keno Hill produced more than 200 million ounces of silver at an average grade of 44 ounces per ton (oz/t) of silver from approximately thirty-five vein deposits between 1913 and 1989(1).
Historical surface trenching and shallow drilling at the Plata Property identified 32 mineralized veins and stockwork zones. Several areas of the property were mined historically for high-grade mineralization yielding 9,020 kg (290,000 oz) of silver from a reported 2,041 tonnes of hand-sorted material, equivalent to a recovered silver grade of approximately 4,420 grams per tonne (g/t) silver.
2021 WORK PROGRAM
Honey Badger completed the planned Phase 1 program on the property on August 22, 2021. The program comprised detailed structural and lithological mapping in the core region of the property, accompanied by rock and channel sampling of several historical occurrences. In all, 48 samples were collected during the Phase 1 program, in addition to five composite grab samples from approximately 90 historic ore bags. Delays at the assay labs have been a common occurrence in releasing timely results from the program. Assay results from the rock and channel sampling program will be released once they have been received and analyzed by the Company.
HISTORIC ORE BAG SAMPLING PROGRAM
During the 2021 program five composite grab samples were collected from approximately 90 partially decomposed ore bags of high-grade, hand-sorted vein material from the P4 and P6 veins. These samples were collected by miners in the past and cached at the Plata airstrip, in order to determine the approximate grade of the mined material. Table 1 below lists the assay results for the samples taken from the ore bags.

Gold assays from these grab samples are still pending.
The Plata property lies within the Selwyn basin, a large Proterozoic to Paleozoic tectonostratigraphic entity that covers much of central and eastern Yukon. Selwyn basin stratigraphy hosts numerous syn-genetic zinc-lead-silver mineral deposits including: the Tom, Jason and other deposits in the MacPass area, several deposits in the Howard’s Pass area, and the Faro, Grum and other deposits in the Anvil mining district. Selwyn basin is also host to the Marg volcanogenic massive sulphide deposit and district-scale epigenetic mineral deposits, including the silver-lead zinc deposits of the Keno Hill Mining Camp and intrusion-related gold deposits of the Tintina gold belt.
Geology within the Plata property is characterized by Upper Proterozoic, Paleozoic and early Mesozoic sedimentary rocks that are imbricated by southeast-striking, southwest-dipping thrust faults, as shown on the property geology map below. Narrow mid-Cretaceous intrusive dykes parallel thrust surfaces. Neoproterozoic Hyland Group rocks comprised of quartz-rich sandstone, grits, shale and minor limestone form much of the hanging wall of the Plata thrust, the main structure running through the property. Devonian to Mississippian shale and chert of the Earn Group unconformably overlie the Hyland Group and are structurally contained between the Plata thrust and the Rogue thrust to the north. The Triassic aged Jones Lake Formation is found in the northern part of the property where it is structurally underlying the Earn Group.
A total of 32 separate mineral showings have been identified to date on the Plata property as shown on the geology map. The core of the property has seen most of the historical work to date and hosts the P1 through P6 zones. Mineralization on the property is divided into in three main types:
1) High-grade argentiferous siderite-sulphide veins generally found as southwest striking, steeply dipping fault veins (Type I). The best mineralized Type I veins occur in dilatant zones developed steeply dipping faults that formed in competent strata, such as Hyland Group quartz-rich siliciclastic rocks and Earn Group chert. Mineralized zones range from a few centimetres to 10m wide and up to 100m long. Zones are characterized by disseminated to massive galena, tetrahedrite and sphalerite within a gangue of siderite and minor quartz, barite and calcite. The zones commonly grade between 1700 and 10,000 g/t silver with 30 to 70% lead. The P2 zone is the best example of Type II mineralization; however, numerous showings are located outside of the P2 zone in both the hanging wall and the foot wall of the Plata thrust.
2) High- to medium-grade auriferous and argentiferous, sulphide-quartz-clay veins located along the Plata thrust and associated structures (Type II). These veins have good lateral and downdip consistency with strike-lengths of up to 800 m and downdip extension of up to 580 m reported. The P3 and P4 zones host Type II veins and the two zones combined is known as the Aho zone because of the consistency in mineralization between the zones. Type III veins consist of fine- to medium grained bands of arsenopyrite, pyrite, galena, boulangerite, tetrahedrite and sphalerite in quartz and clay. Grades from drill core through Type II veins typically return between 5 and 1200 g/t silver with 0.3 to 8.5 g/t gold, 1 to 8% lead and 1 to 6% zinc over thickness of 0.3 and 2 m. High-grade grab samples of massive tetrahedrite and boulangerite from Type II veins returned 78.6 g/t gold and 19,334 g/t silver.
3) Type III veins are characterized by medium- to low-grade argentiferous and auriferous, widely spaced clay and scorodite altered quartz-filled fractures hosting disseminated galena, tetrahedrite and sphalerite. The P-2B occurrence hosts Type III veins. Very little work has occurred on Type III veins, and as such there is little information on their overall abundance and grade.
PLATA – KENO HILL SIMILARITIES
The stratigraphic and structural settings of Plata and the Keno Hill district are remarkably similar, as is the mineralization. Both districts are hosted within Selwyn basin stratigraphy adjacent to Early Cretaceous thrust faults and have large Mayo suite intrusions within 10 km of mineralization. Early gold-bearing veins reported at Keno Hill closely resemble Type II veins identified at Plata. In both districts, these fault veins are dominated by quartz gangue and contain elevated arsenic and antimony. The main silver mineralization at Keno Hill occurs in veins hosted within extensional fault systems. These veins are characterized by minerals containing iron, manganese, sulphur, antimony, lead, zinc, cadmium and silver in a gangue of siderite. The Type I veins at Plata occur in extensional faults that host silver, lead and zinc mineralization associated with elevated antimony, sulphur and cadmium. At both districts, faults and associated veins hosting higher-grade silver mineralization cross-cut earlier gold-enriched mineralization.
All analyses of rocks samples from the 2021 Plata program were performed by ALS Minerals with sample preparation in Whitehorse and assays and geochemical analyses in North Vancouver. Rock samples were routinely analyzed for gold by fire assay followed by atomic absorption (Au-AA24 and 33 other elements by four acid digestion with inductively coupled plasma-atomic emission spectroscopy analysis (ME-ICP61). Samples that exceeded the detection limits of the routine methods were assayed for silver, lead and zinc by inductively coupled plasma-atomic emission spectroscopy (Ag/Pb/Zn – OG62) and samples that exceeded the detection limits for gold by gravimetric analysis (Au-GRA22).
