Announces Acquisition of Additional Ground at Its
Candelaria Silver Mine Project, Nevada
Vancouver, British Columbia--(Newsfile Corp. - March 5, 2018) - Silver One Resources Inc. (TSXV: SVE; OTC Pink: SLVRF;
FSE: BRK1 - "Silver One" or the "Company") is pleased to provide an update on the drilling and sampling of the historic heap
leach pads at its past producing Candelaria silver project in Nevada.
The sonic drill program completed December 2017 (see
Company news release of January 3, 2018) consisted of 1,110 metres in 45 holes on the historic heap leach pads, stockpiled
material and old dumps left over from previous operations.
Assay results for approximately 30 drill holes are currently pending
and will be reported once all have been received from the lab.
Composite samples will be prepared based on the final results for metallurgical testing.
The metallurgical results will assist in
determining the best methods to potentially recover silver from the old heaps, stockpiles and dumps.
A decision will then be
made regarding further studies to examine the economics associated with the recoveries of silver.
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.
Historical information was obtained from "Geology of
the Candelaria Mining District, Mineral County, Nevada, 1959, Nevada Bureau of Mines, Bulletin 56", and the SSR Mining Inc.
technical report titled "Candelaria Project Technical Report" dated May 24, 2001 (filed on SEDAR June 20, 2002), prepared by
Pincock Allen & Holt.
Greg Crowe, President and CEO of Silver One Resources commented: "As we continue advancing our Candelaria silver project
in Nevada, the importance of this historic producer becomes more apparent. We believe there are several upside
opportunities.
Presently the company is investigating potential for the recovery of silver from the historic heap leach pads. Drilling in 2001
outlined very high-grade intercepts (up to 14 m averaging 670 gm/t silver) down dip from the Mount Diablo open pit, suggesting
the possibility for a high-grade zone at depth. Additionally, numerous historic workings along-strike from the two open pits,
Mount Diablo and Northern Belle, suggest a strong possibility of identifying additional mineralization to the east and west of the
historic resource area outlined by SSR Mining in 2001.
We are looking forward to the metallurgical test results which are the next important stage in the development of Candelaria.
These results will help us determine the economic viability of recovering the substantial amount of silver left behind from previous
operations."
New Claims Acquired
Silver One is continuing to expand its ground holdings at Candelaria.
Extensive historic mining activities were carried out
outside the area of the two main open pits — Northern Belle and Mount Diablo.
As such, the Company has entered into an
agreement to acquire 10 non-patented mineral claims located along the eastern structural projection of the Candelaria
mineralized system.
These claims are located immediately east of the former producing Mount Diablo open pit.
Silver One has
acquired these claims for the consideration of US$10,000 plus the issuance of US$10,000 in Silver One shares at the market
price based on TSX Venture Exchange approval.
Historical Resource Estimate — Candelaria Project
SSR Mining Inc. acquired the Candelaria Project in 2001 and reported in a technical report titled "Candelaria Project Technical
Report" dated May 24, 2001 (filed on SEDAR on June 20, 2002), prepared by Pincock Allen & Holt, the historical mineral
resource estimate shown in the table below.
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 estimate as current mineral resources.

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 data base for the historical
resource estimate
(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 mineralized 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 mineralized 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
.
