Westhaven Gold Corp. (TSX-V:WHN) is pleased to
announce the results from its Mineral Resource Estimate (MRE) at
its 100% owned 17,623-hectare Shovelnose Gold Property. The
Shovelnose Gold Property is located within the prospective Spences
Bridge Gold Belt (SBGB), which borders the Coquihalla Highway 30 km
south of the City of Merritt, British Columbia (Canada).
The initial open-pit constrained MRE reported
below (Table 1) is of the South Zone, and was completed by P&E
Mining Consultants Inc., based on a total of 145 surface drill
holes (56,491 m), 25,920 drill core analyses, 3,302 bulk density
measurements, and preliminary metallurgical testwork.
Shovelnose South Zone MRE
Highlights:
- 791,000 ounces of gold and
3,894,000 ounces of silver Indicated.
- 263,000 ounces of gold and 1,023,000 ounces of silver
Inferred.
- 75% of the MRE in the
higher confidence Indicated classification: 10.60 million tonnes at
2.47 g/t for 841,000 gold equivalent (AuEq) ounces.
- Average AuEq grade of
Indicated MRE is 7 times higher than the cut-off grade,
demonstrating excellent potential for future economic extraction
(Table 2).
- Indicated mineralization is largely associated with the
individual vein zones, whereas the Inferred is associated with the
broader Veinlet Domain (please see Figure 1).
- This MRE is based on
potential open-pit extraction – an MRE based on potential
underground mining is in preparation and will be reported in the
coming months.
- South Zone is just one of the many known mineralized
zones on the Shovelnose Gold Property.
- Shovelnose is situated off a major highway, near grid
power, rail, large producing mines, and within easy commuting
distance from the City of Merritt.
Westhaven CEO and President, Gareth Thomas,
notes “This is the first Mineral Resource Estimate on the
Shovelnose Gold Property, and we are pleased to report a starting
inventory of over a million ounces of gold from the first of
multiple mineralized zones. It is important to highlight that 75%
of this Mineral Resource is in the Indicated classification and
grades 2.47 g/t AuEq. Our technical team sees significant Mineral
Resource expansion potential along this key trend (see Figure 3
& 4). The 2022 expansion and exploration drill program will
begin shortly, focusing on the FMN Zone, where high-grade gold
mineralization (15.97 metres of 9.15 g/t Au) was intersected in
drilling last year. Targeting new discoveries on undrilled
exploration targets within this large, underexplored property will
also remain a key focus going forward.”

1. Mineral Resources that are not
Mineral Reserves do not have demonstrated economic
viability.2. The estimate of Mineral Resources may
be materially affected by environmental, permitting, legal, title,
taxation, socio-political, marketing, or other relevant
issues.3. The Inferred Mineral Resource in this
estimate has a lower level of confidence than that applied to an
Indicated Mineral Resource and must not be converted to a Mineral
Reserve. It is reasonably expected that the majority of the
Inferred Mineral Resource could potentially be upgraded to an
Indicated Mineral Resource with continued exploration.4.
The Mineral Resources were estimated in accordance with the
Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM
Standards on Mineral Resources and Reserves, Definitions (2014) and
Best Practices Guidelines (2019) prepared by the CIM Standing
Committee on Reserve Definitions and adopted by the CIM
Council.5. Wireframe constrained assays were composited
to 1.0m lengths and subsequently capped between no cap to 95 g/t
for Au and no cap to 290 g/t for Ag. 6. Grade
estimation was undertaken with ID3interpolation.7.
Wireframe constrained bulk density was determined from 1,179
samples. Mineralization bulk density for veins is 2.54 t/m3, for
the Veinlet Domain 2.52 t/m3, and for overburden 2.0 t/m3.8.
Au and Ag process recovery value was
95%.9. US$ metal prices used were $1,675/oz for Au
and $21.50/oz for Ag with a USD:CD FX of
0.77.10. CDN$ operating costs used were $3/t
mineralized material mining, $2.50/t waste mining, $2.00/t
overburden mining, $18/t processing and $5/t G&A. 11.
Pit slopes were 50º in rock and 30º in overburden. 12.
AuEq g/t (gold equivalent in grams per tonne) = Au g/t + (Ag
g/t/77.9).13. Tonnage is in 000’s tonnes (k); Contained
Au and Ag in 000’s troy ounces (koz).14. Numbers may
not add due to rounding.15. The Effective Date for the
MRE is January 01, 2022.

A total of thirteen mineralization veins and an
encompassing low-grade halo (‘Veinlet Domain’) were interpreted and
constructed, as shown in both plan view (Figure 1) and as a
representative cross section (Figure 2) below. Models were
developed for each vein using the drill core field logs and assays,
and represent continuous gold and silver mineralization constrained
with a cut-off value of 0.35 g/t AuEq (gold equivalent = Au g/t +
Ag g/t/77.9) to a minimum thickness of 2 m drill core length. The
3-D constraining domain wireframes were treated separately for the
purposes of rock coding, statistical analysis, compositing limits,
and definition of the extent of potentially economic
mineralization. All mineralization veins were clipped by the
overburden surface.
The Mineral Resource was classified as either
Indicated or Inferred based on the geological interpretation,
variogram performance and drill hole spacing. Indicated Mineral
Resources were classified within the veins using at least two holes
within a spacing of 45 m or less. Inferred Mineral Resources were
classified for vein blocks at a lower density of drilling, and for
the entire Veinlet Domain. Mineralization of the South Zone is
considered to be potentially amenable to open pit mining methods,
and the Mineral Resource Estimate reported herein is constrained
within a pit shell based on a gold equivalent cut-off of 0.35 g/t.
Additional mineralization exists outside of that pit shell.
Mineralization at the South Zone may also be potentially economic
for underground mining, however, that work has not yet been
undertaken. The reader is cautioned that Mineral Resources that are
not Mineral Reserves do not have demonstrated economic
viability.
Drilling, assaying and exploration work on the
South Zone demonstrate spatial continuity of the mineralization
within potentially mineable shapes, and are sufficient to indicate
a reasonable potential for economic extraction, thus qualifying it
as a Mineral Resource in accordance with the Canadian Securities
Administrators’ National Instrument 43-101 and was estimated in
conformity with the Canadian Institute of Mining, Metallurgy and
Petroleum (“CIM”) “Estimation of Mineral Resource and Mineral
Reserves Best Practice Guidelines” (November 2019) and the
definitions set out in the 2014 CIM Definition Standards.
A Technical Report to support the initial
Mineral Resource Estimate for the Shovelnose Gold Property – South
Zone, prepared in accordance with National Instrument 43-101, will
be filed on SEDAR (www.sedar.com) within 45 days of this news
release.

Qualified Person Statement
The Mineral Resource Estimate for the Shovelnose
Gold Property – South Zone was prepared by Yungang Wu, P.Geo.,
Antoine Yassa, P.Geo. and Eugene Puritch, P.Eng., FEC, CET of
P&E Mining Consultants Inc., Brampton, Ontario, all Independent
Qualified Persons as defined by National Instrument 43-101 -
Standards of Disclosure for Mineral Projects. Mr. Puritch has
reviewed and approved the technical contents of this news
release.
QA/QC
Drill core samples were prepared using the
PREP-31 package in ALS’s Kamloops facility. Each drill core sample
is crushed to better than 70% passing a 2 mm (Tyler 9 mesh, US Std.
No.10) screen. A split of 250 g is taken and pulverized to better
than 85% passing a 75-micron (Tyler 200 mesh, US Std. No. 200)
screen. Subsequently 0.75 g of this pulverized split is digested by
Four Acid and analyzed via ICP-MS (method code ME-MS61m (+Hg)),
which reports a 49-element suite of elements. All samples are
analyzed by Fire Assay with an AES finish, method code Au-ICP21 (30
g sample size). Additional Au screening is performed using ALS’s
Au-SCR24 method, whereby select samples are dry screened to 100
microns. A duplicate 50 g fire assay is conducted on the undersized
fraction as well as an assay on the entire oversize fraction. Total
Au content, individual assays and weight fractions are reported.
All analytical and assay procedures are conducted in ALS’s North
Vancouver facility. Westhaven’s QA/QC program includes the
collection and submission of regular field core duplicates
(quartered core), as well as laboratory and field certified
reference materials inserted every 25 samples. At least one field
blank is inserted in every batch of 25 samples, with additional
blanks inserted following samples with visible gold. Selected drill
core pulps and reject material were submitted to a third-party
laboratory for check assays.
