About the Plata Silver Property

Historic exploration at the Plata Silver Property from 1969 to 2011 identified thirty-two (32) known mineralized zones, extending over a 2.5 kilometre area, hosting narrow high-grade silver, gold, lead and zinc-bearing veins and stockworks. Mineralization at Plata is believed to be associated with hydrothermal fluids related to the Tombstone intrusive suite and bears similarities to the prolific Keno Hill Silver Mining Camp, Canada’s second largest primary producer of silver with production from approximately thirty-five (35) vein deposits between 1913 and 1989.

Samples were submitted to ALS Minerals in North Vancouver.  Multi-element analysis was completed for rocks and drill core by ME-ICP61, and soils by ME-ICP41.  Gold analysis was completed using AU-AA25.  Overlimit samples were analyzed using ME-OG62 respectively. All analysis passed standard QA/QC procedures.

High priority target areas at Plata include

  • P-4 Zone: The P-4 Zone has undergone more extensive drilling relative to other targets at Plata and demonstrates continuous mineralization over 200 metres of strike length that remains open in all directions. Average grades and widths from fourteen (14) core drill holes in 1987 were 1.9 metres grading 337 g/t silver, 3.65 g/t gold, 1.59% lead and 1.7% zinc.
  • P-3 Zone: At the P-3 Zone, rock samples have returned extremely high gold assays (up to 78.3 g/t) and chip sampling returned 1.96 metres grading 2,383 g/t silver, 9.85 g/t gold and 7% lead.
  • P-6 Zone: Drilling in 2011 confirmed the continuity of significant polymetallic silver mineralization at depth and laterally over a strike length of 150 metres. Highlighted drill intercepts include 1.0 metre grading 1,655 g/t silver and 1.09% zinc, and 6.63 metres grading 164 g/t tonne silver and 2.34% zinc. Veining mapped at surface and anomalous soil geochemistry suggest the P-6 structure may extend for 500 metres to the northwest.
  • P-2 Zone: Detailed trenching of the P-2 Zone returned a weighted average of 812 g/t silver, 24.48% lead and 17.02% zinc across an average width of 1.93 metres for a strike length of 85 metres. Drill holes targeting the P-2 Zone yielded intercepts of up to 1,060 g/t silver and 3.86% zinc over 0.87 metres and 110 g/t silver and 39.77% zinc over 0.93 metres.

Importantly, drilling from 2008 to 2011 has demonstrated that the P-3 and P-4 veins are part of a larger, semi-continuous, mineralized system referred to as the Aho Zone, which is developed within the plane of the Plata Thrust Fault and varies from 0.3 to 3.0 metres in width. This zone extends intermittently over a total strike length of 800 metres and to a maximum of 580 metres downdip and remains open to extension along strike and downdip (Figure 1).

Plata Silver Project Overview

Keno Hill Silver District and Plata- Key Similarities

Silver associated with hydrothermal fluids related
to Mayo Suite intrusions

Proximity to major thrust fault: Robert Service
Thrust at Keno Hill and Plata Thrust Fault at Plata

Complex network of faulting and veining

Sedimentary Host Rocks: Quartz-rich siliciclastic
rocks, Keno Hill Quartzite at Keno and Hyland
Group grits and Earn Group chert at Plata,
provide competent strata where continuous, wide
veins systems can develop

Mineralization: High-grade argentiferous
sulphide-siderite veins, with galena, sphalerite
and tetrahedrite in a gangue of minor quartz-

*Although high to medium grade auriferous and argentiferous, sulphide-quartz-
clay veins are also found within the Plata Thrust, such as at the P-3 and P-4 veins
