Silver Spruce Receives First Assays from Kay Mine VMS Samples
Silver Spruce Receives First Assays from Kay Mine VMS Samples
December 7, 2017 - Bridgewater, NS - (TSXVSE:SSE)(Frankfort S6Q) – Silver Spruce Resources Inc.
("Silver Spruce" or the "Company") is pleased to announce that it has received its first assays of
mineralized rock samples taken from the development/production dumps at the Kay Mine in Arizona.
These first twenty -five s amples were taken for data verification purposes to confirm the tenor of
mineralization reported by Exxon Minerals and previous developers of the mine . Eighteen of the samples
consisted of volcanogenic massive sul phide (VMS) and sul phide-bearing material. Assay values from
these samples are listed in the table below with their respective over-limit values.
“We are very encouraged by the assay values produced from samples taken during several Company -
hosted, third-party tours of the Kay Mine p roject in September and October,” stated Karl Boltz, CEO of
Silver Spruce. “These assays are a good indication of met al values in the development rock which was
taken from the underground levels of the mine during its initial construction and production preparation
phase, prior to 1957, when the mine was flooded. Assay results from an additional fourteen samples are
pending.”

Media Release
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 <1m m to
2cm in thickness were comprised of pyrite -dominant and base metal -bearing units. Coarse -grained pods
and veinlets of chalcopyrite and sphalerite from 1-3cm also infill silicified rhyolite breccias.
Kay Mine Background
The Kay VMS deposits were develop ed 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 b ulk 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 1949
to 1953, and shipped to various smelters in Arizona and Texas. An estimated 15,000 tons of low grade
material was reported on the surfac e 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 to ns. 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, logi stics 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 t he 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 (blank s, standards, duplicates) were inserted into the
batch of 25 grab samples. ALS Global conducts its own internal Q/QC program of blanks, standards and
duplicates, and the results are provided with the Company sample certificates. The r esults of the ALS
control samp les were reviewed by the Company’s QP and all 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 analy zed 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).
