Silver Predator owns a 100% interest in the Taylor Mine and Mill that is located in White Pine County, Nevada, 27 km (17 miles) south of the town of Ely and 4.0 km (2.5 miles) east of US highway 50. The property consists of 131 unpatented lode claims, 4 pateneted lode claimsand 5 unpatented mill site claims, subject to a 2% NSR royalty.
Silver Predator’s technical team recently discovered multiple areas of geochemically anomalous gold-silver mineralization immediately east and southeast of the existing mine and mill. While the existing silver resource is open for expansion in multiple directions, the Company’s primary efforts are on exploring the new gold targets as the geologic interpretation is that Taylor shows potential to become a new gold district on the southern end of the Carlin Trend.
Sediment-Hosted Gold Mineralization
the company drill tested newly identified gold targets located south of the existing silver resource. These targets were identified through the Company’s 2012 mapping and soil sampling programs as being highly prospective for Carlin-style mineralization based on geologic features and geochemistry. The detailed mapping program was completed within the existing open pits found that silver mineralization was confined to specific, but predictable, host rocks and fault zones. The best silver grades were found at the convergence of north-south and northwest-orientated fault zones; structural controls that are repeated at Taylor and typical of other precious metal districts in Nevada, including the northern Carlin Trend.
As the mapping was expanded outward from the resource area, silica alteration, intrusives, and antimony prospects related to N-S and NW faulting were found to the east and southeast of the resource area. This mapping was the first indication that previous mining was focused on only a minor portion of a much larger District-scale precious metals system.
A soil geochemistry program was completed in late 2012 to prioritize target areas. The soil program identified highly anomalous gold, silver, antimony, arsenic and mercury in mapped areas coincident with favorable host rocks, intrusives, jasperoid silica and the patterned N-S/NW fault sets. In 2014, select outlying targets were drill tested to the east and southeast, as well as within the existing silver resource area. Drilling near the Antimony prospect returned the most significant results while holes testing prospective targets to the south encountered strong alteration but did not return significant mineralization.
Significant drill results include::
- SPT-66 with 18.3 meters of 1.02 g/t gold starting at surface;
- SPT-65 with 24.4 meters of 0.68 g/t gold starting at surface and including 12.2 meters of 0.85 g/t gold; and
- SPT-62 with 12.2 meters of 0.78 g/t gold and 88.3 g/t silver starting at 71.6 meters.
The soil results include the following:
- Five samples assaying over 1 g/t gold (Au), including values of 1.3, 1.5 and 1.7 g/t Au;
- 126 samples (11%) assaying greater than 0.2 g/t Au;
- 224 samples (19%) assaying greater than 0.1 g/t Au; and
- The 1.3 g/t soil sample was located approximately 15 feet from a small outcrop of Pilot Shale that was weakly silica altered, but assayed 5 g/t Au and 12 g/t Ag.
Silver Resource Expansion
The current silver resource remains open along strike and laterally in many areas. Identified areas for resource expansion, include mineralization along the Argus Fault north and south of the Taylor Shaft. Over 100 historic drillholes from this area, many significantly mineralized, were removed from the resource estimate due to selective sampling and incomplete assay data. An in-fill drilling program could provide the confirmation to add this mineralization to an updated resource estimate.
The “Bulls Eye” target is also an area targeted for resource expansion potential with recently identified higher-grade silver mineralization, both near surface and continuing at depth. Mineralization is controlled by an intersecting series of north-south and northwest orientated faults that are intruded by rhyolite dikes and sills, a prime geologic environment.
There are several other targets and areas identified for further drilling which have the potential to further expand current resources.
The current Taylor mineral resources were reported at a 1.0 oz/ton silver cutoff grade as summarized in the table below. A cutoff grade of 1.0 oz/ton silver was based upon assumptions of (in USD): a $30 per ounce silver price, 90% recovery, mining costs of $2.50/ton for in situ material and $2.00/ton for unconsolidated material, mill process costs of $21.50 per ton, and G & A costs of $2.50 per ton. In order to meet the criteria for "reasonable prospects for economic extraction" as required by CIM, the block model was constrained by an optimized open pit using the baseline silver price and operating costs. All mineralization is above the water table and oxidized.

The Taylor silver deposit is an epithermal, high-silica, low-sulfide replacement deposit in Devonian carbonate rocks. The deposit occurs as argentiferous jasperoid replacement bodies in the upper Guilmette Limestone. These jasperoid bodies are localized by a combination of steep, north-south and northwest trending structural conduits and preferred host rock units consisting of reactive silty to sandy transitional carbonates. Silver mineralization is often more concentrated adjacent to the felsic dikes and sills commonly found throughout the resource area and elsewhere on the property. Silver-bearing minerals identified to date, include native silver and the oxides argento bindheimite and argento jarosite, and locally preserved relict sulfides, including acanthite, bournonite, and tetrahedrite. Gangue minerals, include quartz as jasperoidal replacement silica bodies commonly hosting mineralization, the iron oxides hematite and jarosite, and silver related oxides of copper and zinc. Overall, the faulting and folding within the resource area define a broad domical (to antiformal) north and south-plunging structure, centered on the Bishop Pit. The structural and stratigraphic controls resulted in the jasperoid forming large, relatively flat, tabular bodies. Elsewhere on the property, mineralization occurs in the silicified portions of the Chainman shale and along previously mentioned north-northwest trending structures as well as in jasperoids and silicified structures cropping out in the underlying Joana limestone, particularly near the upper contact with the Chainman.
The Taylor property was a high grade underground silver producer during the late 1880s, and again in the 1960s. The most signficant production history occurred from 1981 to 1984, when Silver King Mines produced over 5 million ounces of silver from several open pits. The mine closed due to low silver prices, leaving significant current resources pre-stripped in close proximity to the existing mill.
In 1989, Alta Gold (successor to Silver King Mines) expanded the Taylor mill to include copper, lead and zinc flotation circuits to process ore from a nearby gold mine. The mill operated until 1991 when the nearby mine closed.
Silver King Mines, and its successor, held the property from 1966 to 2000 before the property was acquired by First National Bank of Ely for monies owed. Fury Explorations Ltd. entered into an agreement with First National Bank of Ely in 2006 to earn a 100% interest. Fury Exploration Ltd. was later acquired by Golden Predator Corp.
Modern exploration has been conducted by Fury Explorations Ltd., Golden Predator Corp. and Silver Predator Corp. between 2006 and 2014 on the resource area with little exploration in the surrounding area.
