Sabre Gold Mines Corp. (TSX:SGLD; OTCQB:SGLDF) (the “Company” or
“Sabre Gold”) is pleased to announce a resource update for the
Company’s road accessible Brewery Creek Gold Project located in
Yukon Territory, Canada. The improved classification of measured
and indicated mineral resources increased by 355,000 ounces gold
(32%) in all categories and is a result of the Preliminary Economic
Assessment (“PEA”) that is nearing completion with results to be
provided in January 2022.
Giulio T. Bonifacio, President and Chief
Executive Officer of Sabre Gold, stated: “We are very pleased with
the significant increase in the Measured & Indicated categories
of over 350,000 ounces. Sabre Gold intends to further expand gold
resources at Brewery Creek in 2022 which will further enhance what
are expected to be attractive economics in our upcoming PEA. The
PEA is advanced in several categories as the predecessor company
was initially targeting completion of a feasibility study. We are
also pleased to report our permitting remains on schedule while now
focusing on further expanding the previously permitted footprint
for purposes of increasing the annual production profile.”
Mineral Resource
EstimateMeasured, Indicated and Inferred Mineral Resource
estimates have been produced for the eleven named deposits at
Brewery Creek. The results of the estimation are that the Brewery
Creek Project has Measured and Indicated Mineral Resources totaling
34.5 million tonnes at 1.03 g/t, containing 1.14 million ounces of
gold. Inferred resources total 35.9 million tonnes at 0.88 g/t
containing 1.02 million ounces of gold. Total Mineral Resources are
shown in the below table:

A Lerchs-Grossmann optimization pit shell
constrained the resource using a $2,000/oz gold price and the
cutoff grade used is based on a gold price of $1,500/oz and is an
internal cutoff grade. The process cost used for the pit shell and
cutoff grade includes project general and administrative expenses
as well as an average haulage cost to transport process material to
the leach pad. Only leachable Measured, Indicated and Inferred
Resources are being considered in the ongoing PEA.
During the work for the PEA, Gustavson reviewed
the classification utilized to classify material as Measured,
Indicated and Inferred and updated the classification to more
appropriately distribute the material into the classification
categories, based on an average drill spacing instead of a closest
point analysis. This technique utilizes a cell declustering
algorithm to quantify drill spacing taking into account geologic
anisotropy.
The Mineral Resource Estimate was prepared by
Gustavson Associates, LLC (Gustavson). The resource estimate was
conducted in accordance with Canadian National Instrument 43-101
Standards of Disclosure for Mineral Projects (NI 43-101), June
30,2011, and Canadian Institute of Mining, Metallurgy and Petroleum
(CIM) “Best Practices and Reporting Guidelines for Mineral
Resources and Mineral Reserves”, May 10, 2014.
Mineral resources are not mineral reserves and
do not demonstrate economic viability. The quantity and grade of
inferred resources reported herein are uncertain in nature and
exploration completed to date is insufficient to define these
Mineral Resources as indicated or measured. There is no certainty
that all or any part of the mineral resource will be converted to
mineral reserves. Mineral Resources are not mineral reserves and
may be materially affected by environmental, permitting, legal,
socio-economic, marketing, political, or other factors. Quantity
and grade are estimates and are rounded to reflect the fact that
the resource estimate is an approximation. Gustavson knows of no
environmental, permitting, legal, title, taxation, socio-economic,
marketing, political, or other factors that could materially affect
the mineral resource.
Brewery Creek Resource Expansion
OpportunitiesSabre Gold is developing in-fill and
expansion drill programs for Brewery Creek in 2022. The additional
in-fill drilling will focus along the reserve trend deposits which
are the focus of the PEA to elevate additional material from
inferred into measured and indicated.
Expansion drilling will focus on three areas
with existing mineral resources, Classic, Lonestar and Sleeman
deposits.
Classic DepositThe Classic
deposit is located approximately 3 km south of the main Brewery
Creek deposit trend. The deposit was originally discovered in 1991
(Hemlo Gold Mines Inc.-Loki Gold Corporation) through a southern
grid expansion, the Classic Zone was then being classified as an
isolated, arsenic gold anomaly. To date, the Classic deposit
remains poorly understood with current interpretations based on the
underlying syenite pluton and faulting. It is currently defined by
52 reverse-circulation drillholes and 17 core holes, totaling
13,478 meters. The currently identified mineralization lies
entirely on the southwest side of the Classic Fault. The deposit is
~1400 meters in length, ~30 meters wide, and ~240 meters down
dip.
Predominant rock units hosting mineralization
contain variable percentages of syenite (alkali) and biotite
monzonite (increasing plagioclase). Mineralization is found to
exist within centimeter-scale sheeted quartz veinlets.
Structurally, the Classic Zone is open at depth and in both
directions along strike. Cutting across the eastern portion is the
northwest trending and steeply southwest dipping Classic fault
which is mapped to be post intrusion and post mineralization. A
similar intrusive complex which displays altered mineralization
akin to the Classic is mapped within the footwall of the Classic
Fault with a dextral offset of 1.5 km (Lindsay, 2006) to the
southeast.
LonestarThe Lone Star
mineralized area lies along the northeast side of the Classic
Fault, southeast of and adjacent to the Classic Zone. Surface
mineralization was first recognized by soil sampling in the 1990’s
but the area remained untested until 2012. Drilling in 2012
consists of 17 core holes and 12 RC holes, totaling 6,147 meters.
The deposit is ~1100 meters in length, ~20 meters wide, and ~220
meters down dip.
The same alkalic suite of intrusions that host
Classic also host Lone Star. The suite intruded along a zone with
an azimuth of 290°, centered on and sub parallel to the
post-mineralization Classic fault. The suite contains syenite,
biotite monzonite, monzodiorite, diorite, and gabbro; syenite is
the most abundant. The more mafic compositions intrude the syenite
and the most mafic lithologies were last to intrude. The biotite
monzonite intrusions commonly form very well developed,
course-grained skarn halos where adjacent to limestone and carry
copper-gold mineralization.
Alteration includes development of a propylitic
mineral assemblage of chlorite, calcite and pyrite, and local
development of sheeted quartz-carbonate-pyrite-arsenopyrite
±chalcopyrite veins. Three styles of mineralization occur at Lone
Star; elevated Au associated with skarns, disseminations in
syenite, and auriferous sheeted quartz veins. The geometry of the
system is poorly understood; it remains open in both strike
directions and at depth. The Sleeman deposit is located to the east
of the BCRT and may possibly demarcate the easternmost extent of
the trend. It was discovered by mapping, soil sampling and
trenching, and was first drilled in 1992. The zone is currently
defined by 7 reverse-circulation drillholes and 58 core drillholes,
totaling 11,374 meters. A linear distance of approximately 9 km
separates the zone from the heap leach pad. The deposit is ~500
meters in length, ~25 meters wide, and ~220 meters down dip.
SleemanMineralization at
Sleeman is associated with an altered tabular-shaped quartz
monzonite intrusion that cuts siltstone of the Steel formation and
graphitic argillite of unknown affinity. The intrusion strikes 120°
azimuth and dips 65° southwest. It has a known strike length of 500
meters and is open in both strike directions and at depth. A
secondary trend of mineralization oriented approximately 060°
azimuth and dips approximately 45° to the southeast is noted in the
western hanging wall to the main tabular body. A poorly constrained
fault may displace the southeast portion of the sill down to the
southeast.
Alteration at Sleeman includes locally intense
clay development after feldspars and texture destructive
silicification. All mineralization is associated with the altered
and veined areas. Hairline to millimeters-scale quartz-pyrite
stockworks and planar 2-10 millimeters-scale quartz-pyrite veins
with illite selvages occur within the alteration envelope. The
planar quartz veins are paragenetically younger than the
stockworks.
The style of veining and alteration at Sleeman
is similar to other deposits found within the BCRT with the
exception of the presence of elevated base metal concentrations,
particularly lead and zinc.
