Development Rock Sampling, Arizona, USA
March 1 4, 2018 - Bridgewater, NS - (TSXVSE:SSE)(Frankfurt S6Q) - Silver Spruce
Resources Inc. ("Silver Spruce" or the "Company") is pleased to announce that it has
received its second batch of assays of mineralized rock samples taken from the
development/production dumps at the Kay Mine in Arizona. This second batch consisted of
fourteen additional samples taken for data verificati on purposes to confirm the tenor of
mineralization reported by Exxon Minerals Corporation and previous developers of the mine.
The samples consisted of volcanogenic massive sulphide (VMS) and sulphide -bearing material.
Assay values from these samples are l isted in the table below with their respective over -limit
values.

"We continue to be impressed with assay values from the dump material that was taken from
underground workings when the mine was being developed for production, prior to 1957,” stated
Karl Boltz, CEO of Silver Spruce. "Together, with the initial twenty -five samples assayed in
December 2017, shown below, these positive assay results are part of our ongoing efforts to
confirm the resource stated by Exxon Minerals, in 1982, after ten years of advanced exploration,
confirmation drilling and resource estimation at the project.”

The majority of the sulphide -bearing samples were collected from the historic
development/production dumps at Shaft #4. It should be noted that the grab samples are selective
by nature and values reported may not be representative of mineralized zones. Examination of
the mineralized material indicated disseminated to semi-massive to massive sulphides, consisting
of pyrite, sphalerite, chalcopyrite and galena in banded, lenticular and breccia to replacement
textures. Compositional layering from <1mm to 2cm in thickness were comprised of pyrite -
dominant and base metal -bearing units. Coarse -grained pods and veinlets o f chalcopyrite and
sphalerite from 1-3cm also infill silicified rhyolite breccias.
Kay Mine Background
The Kay VMS deposits were developed for production on eleven levels and accessed via four
shafts prior to 1957, when the pumping station was damaged and the mine was flooded. Records
obtained by Silver Spruce indicate that approximately 1,550 tons of ore grading 5.6% Cu, with
individual bulk samples from 2.95-9.47% Cu, with Pb, Zn, Au and Ag credits, was mined on the
250 foot and 500 foot levels from 1 949 to 1953, and shipped to various smelters in Arizona and
Texas. An estimated 15,000 tons of low grade material was reported on the surface dumps in
1956. The last production of 70 tons grading 5.7% Cu selected from the surface dumps was
shipped by a private owner in 1966.
In 1972, Exxon acquired the project with the goal of commencing production of the known high-
grade Cu-Zn-Pb-Ag-Au ores. Exxon's internal geological reports referred to the mineralization
defined by drilling and historical underground exploration, under the then existing mining
standards, as "proven and probable ore" of 6.4 million tons with a potential of over 20 million
tons. These resource estimates and terminology are to be considered historical and not compliant
with current NI 43-101 guidelines.
The Company believes that the previous work conducted by Exxon was completed to a high
standard of competency and credibility. Silver Spruce is developing exploration programs to
document the tonnage and grade of the Kay mineralization and develop a resource estimate to
conform to the present National Instrument 43-101 standards.
Silver Spruce also is investigating the cost, logistics and permitting requirements to de-water the
mine workings for direct access to the mineralization.
Quality Assurance and Quality Control
Samples were collected by the Company's QP, packaged and shipped in sealed pails by
commercial carrier to northern Washington, and delivered by the QP to British Columbia for
sample description and preparation of the assay splits. The rock samples were sawn, or split as
required, with a representative cross section or portion bagged and sealed in packages by the QP
and delivered by commercial carrier to ALS Global's sample preparation facility in North
Vancouver. The sample pulps were transferred internally to ALS Global's analytical facility, also
located in North Vancouver, for analysis. ALS Global in North Vancouver, British Columbia,
Canada, is a facility certified as ISO 9001:2008 and accredited to ISO / IEC 17025:2005 from
the Standards Council of Canada. Photographs of the individual rock samples, as -received and
sawn faces, were collected from each sample prior to shipment, and will be made available on
the Company web site in due course.
No independent or in-house quality control samples (blanks, standards, duplicates) were inserted
into the batch of twenty-five grab samples or the second batch of fourteen samples. ALS Global
conducts its own internal QA/QC program of blanks, standards and duplicates, and the results are
provided with the Company sample certificates. The results of the ALS control samples were
reviewed by the Company's QP and were within acceptable tolerances. All sample and pulp
rejects are stored at ALS Global pending full review of the analytical data, and future selection
of pulps for independent third-party check analyses.
The samples were crushed to 70% passing 6mm (-10 mesh) and a split of up to 250 grams was
pulverized to 85% passing 75 micrometres (-200 mesh). Each pulp was then submitted for
analysis by 4 Acid Digestion followed by Inductively Coupled Plasma Mass Spectrometry (ICP-
MS) multi-element analyses (ALS Code ME-MS61, 48 elements). All base metal analyses that
reach the over-limits of ME-ICP61 are re-analyzed with an Ore Grade method. Over-limit Cu
(>1%), Pb (>1%), Zn (>1%) and Ag (>100ppm) samples are analyzed by Ore Grade 4 Acid
Digestion followed by Ore Grade Inductively Coupled Plasma Atomic Emission Spectrometry
(ICP-AES) for Pb (ALS Code Pb-OG62) and Ag (ALS Code Ag-OG62), and by Atomic
Absorption Spectroscopy (AAS) for Cu (ALS Code Cu-AA62) and Zn (ALS Code Zn-AA62).
Gold was analyzed using 30gram fire assay with Atomic Absorption Spectroscopy (ALS Code
Au-AA23). Over-limit Au (>10ppm) were conducted by 30gram fire assay with Gravimetric
finish (ALS Code Au-GRA21).
