Vancouver, BC, October 31, 2017 - Silver One Resources Inc. (TSXV: SVE; OTC Pink: SLVRF;FSE: BRK1 - “Silver One”) is pleased to announce that it has received permitting from the Bureau of Land Management (“BLM”) to commence drilling of the historic leach pads at its past producing Candelaria silver project in Nevada. Drilling is expected to commence in November 2017.
Greg Crowe, President and CEO of Silver One commented: “With the closing of the previously announced C$4.3 million financing and the receipt of the BLM permit, Silver One is now in a strong position to advance its flagship Candelaria past producing silver project in Nevada. Drill testing of the old leach pads, which have a previously disclosed historic inferred resource (see table below) of over 48 million ounces of silver averaging 1.29 oz/t silver (40 g/t), will be our first priority. Drill samples will be submitted for analytical and metallurgical studies to assess the potential of reprocessing the old leach pads to recover silver in a near-term leaching operation. Silver One will also be exploring the potential for down-dip high grade silver mineralization north of the two past producing open pits and historic resource area, where drill intercepts as high as 670 g/t (21.4 oz/t) over 13.7 metres were encountered. Additionally, numerous old workings that occur along strike from the open pits will be examined to determine the potential of adding new silver resources at Candelaria.” The historical resource estimate was reported by SSR Mining Inc. (formerly, Silver Standard Resources Inc.) in a technical report titled “Candelaria Project Technical Report” dated May 24, 2001 (filed on EDAR on June 20, 2002), prepared by Pincock Allen & Holt. The historical mineral resource estimate used “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource”, which are categories set out in NI 43-101. Accordingly, Silver One considers these historical estimates reliable as well as relevant as it represents key targets for exploration work by Silver One. The qualified person has not done sufficient work to classify the historical estimate as a current mineral resource. Silver One is not treating this historical estimates as current mineral resources.
Further, the historical resource estimate is set forth in the table below:
The data base for the historical resource estimate consists of:
(1) on the Mount Diablo Deposit consisted of 538 drill holes by previous owners and 10 drill holes by Silver Standard Resources Inc. For drill holes that were twinned, the author used the lower of the two values assigned to the original holes. The mineral resource estimate used a kriging estimation method to establish zones with a cut-off grade of 0.5 opt Ag. Ordinary kriging was used to interpolate grades in the block model. The block models were set up with block dimensions of 25 feet by 25 feet in plan and 10 feet in height. The maximum search range used in the higher-grade zone was 235 feet, in the lower grade zone it was 1,000 feet and in the background zone it was 350 feet. Block models more than 300 feet from the nearest composite only constituted 3 percent of the total number of estimated blocks and were assigned to an inferred category,
(2) on the Northern Belle Deposit consisted of 226 drill holes by previous owners, of which a portion of these holes were duplicated for the Mount Diablo Deposit database. The mineral resource estimate used a kriging estimation method to establish zones with a cut-off grade of 0.5 opt Ag. The mineral resource estimate used multiple indicator kriging to interpolate grades in the block model. Block models were set up with block dimensions of 50 feet by 50 feet in plan and 20 feet in height. The maximum search range used in the higher-grade zone was 85 feet, in the intermediate-grade zone was 120 feet and the lower-grade zone was 140 feet and in the lower undifferentiated material below the current pit topography was 260 feet. Block models more than 300 feet from the nearest composite only constituted 3 percent of the total number of estimated blocks and were assigned to an inferred category;
(3) on the Leach Pads consisted of 24,633,000 tons located on Leach Pad 1 and 12,695,000 on Leach Pad 2. The estimate for Leach Pad 1 is based on the fact that silver production indicates 51.5% of total silver was recovered by heap leaching operation, while 81.2% of the soluble silver contact was recovered. Further, the estimate for Leach Pad 2 is based on the fact that silver production indicates 42.4% of total silver was recovered by heap leaching operation, while 71.3% of the soluble silver content was recovered;
(4) on the Low-Grade Stockpile is based on limited and incomplete data and documentation. Material placed on the on the stock piles ranged from 0.5 to 0.65 opt Ag,
To the knowledge of Silver One, there is no new data available since the calculation of the above historical resource estimate and no additional work has been done to upgrade or verify the historical resource estimate.
Candelaria was historically the highest-grade silver producer in the state of Nevada, averaging over 1,250 g/t silver from high-grade vein mining between the mid 1800s and the mid 1900s. Open pit mining operations were undertaken in the 1970s through 1998 by several companies including Nerco and Kinross. Kinross closed the open pit and leach operation in 1998 due to low silver prices. Leaching of the historic pads was not completed leaving a substantial amount of silver unprocessed. It is estimated that the property has produced over 68 million ounces of silver.
