Wolfden Announces Mineral Resource
Estimate for Pickett Mtn. Project
Includes 2.05 Mt at 19.32% ZnEq of Indicated & 2.03 Mt at 20.61% ZnEq of Inferred Resources
THUNDER BAY, ON,
Jan. 7, 2019
/CNW/ -
Wolfden Resources Corporation
("Wolfden" or
the "Company") is pleased to announce a Mineral Resource estimate for its 100% owned
Pickett Mountain high-grade zinc-lead-copper-silver massive sulphide deposit
("the Deposit"),
located in
Penobscot County
in north-eastern
Maine, U.S.A.
Highlights
Indicated Mineral Resource of 2.05 million tonnes at 9.88% zinc, 3.93% lead, 1.38%
copper, 101.58 g/t silver & 0.92 g/t gold (19.32% ZnEq).
Inferred Mineral Resource of 2.03 million tonnes at 10.98% zinc, 4.35% lead, 1.20%
copper, 111.45 g/t silver & 0.92 g/t gold (20.61% ZnEq).
Continued expansion and infill diamond drilling on the Deposit has the potential to upgrade and
expand the mineral resource.
The resource estimate utilized up to hole PM-18-29 from the 2018 drill program that included 27
intersections. Hole 32, a step-out in the West Lens, and hole 35, a step-out in the East Lens,
were subsequently completed following the cut-off date. Both returned impressive intercepts of
massive sulphides with assays pending.
A potential new mineralized lens situated 180 metres to the North and parallel to the East Lens
was discovered by hole 31, where assay results are pending.
"This mineral resource estimate supports our belief that Pickett Mtn. is one of the highest-grade
undeveloped massive sulphide (VMS) deposits in the base-metal sector in
North America
", stated
Don Hoy
, Senior Vice President of Exploration for Wolfden. "Our goal is to further upgrade and
expand the resource while we consider various scenarios that could be used to develop a mining
operation on the project. These types of deposits often occur in clusters and future exploration will
test for additional satellite massive sulphide lenses that could occur elsewhere on the property and in
the large prospective volcanic belt that hosts the Pickett Mtn. deposit. The past producing Buchan's
mine in Nfld., which occurs within the same Appalachian orogenic belt as Pickett Mtn., produced
16.2 million tonnes of ore from five lenses, that averaged 14.5% zinc, 7.6% lead, 1.3% copper, and
126 g/t silver and 1.4 g/t gold over 58 years and was one of the highest grade base metal camps in
Canadian history."
The estimate was completed utilizing data from 70 historic drill holes completed by Getty and
Chevron during the period of 1981 to 1985 and 27 recent drill holes completed by Wolfden over the
last year and utilized wireframe models created by Gems 3D modelling software. The wireframes
were then imported into Hexagon/MineSight software and validated. The resulting geological model
and estimate will form the basis for further infill and expansion drilling and assist in prioritizing
regional exploration targets. Much of the drilling to date has been at a spacing (
+50 m
) that is not
quite tight enough to allow for measured and indicated resources. There remains a significant
opportunity to upgrade the resource with infill drilling and confirming the optimal drill spacing via a
test pattern program. The recent deep drilling results (
+600 m
depth) exhibited some exceptionally
high grades and thereby underscores the potential to further expand resources at depth.
The Mineral Resource Estimate
The Mineral Resource estimate has been prepared, supervised and reviewed by Independent
qualified persons ("QP")
Finley Bakker
, P. Geo.,
Jerry Grant
, P.Geo.,
Brian LeBlanc
, P. Eng., of A-
Z Mining Consultants and has an effective date of
January 7, 2019
. The estimate also included the
input and review of
Andre Labonte
, a resource technician. The technical report to be authored by A-
Z Mining Consultants, as prescribed by National Instrument 43-101, Standards of Disclosure for
Mineral Projects, will be posted on Wolfden's website and SEDAR within 45 days from the date of
this news release. The Mineral Resource estimate was classified into indicated and inferred
categories in accordance with CIM Definition Standards on Mineral Resources and Reserves
adopted by the CIM Council on
May 10, 2014
.
A number of potential cut-off grades for Zinc Equivalent were calculated for each resource category
as represented in the tables below. The tonnage and grade are robust over the intervals chosen. A
9% Zinc Equivalent cut-off was considered to be conservative until further technical studies have
been completed.

Mineral Resource Estimate Parameters and Assumptions
Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
There is no certainty that all or any part of the Mineral Resources will be converted into Mineral
Reserves.
Resources are presented as undiluted and in-situ for an underground mining scenario and are
considered to have reasonable prospects for economic extraction.
The metal prices used to determine Zinc Equivalent (ZnEq) grades where
US$1.20
/pound for
zinc,
US$1.00
/pound for lead,
US$2.50
/pound for copper,
US$16.00
/troy ounce for silver, and
US$1200
/troy ounce for gold. The base case utilized a calculated cut-off grade of 9.00% ZnEq.
Indicated Resources were estimated using a maximum distance of 25 metres from a drill hole
and meeting a single hole minimum.
Inferred Resources were estimated utilizing a no hole minimum and using a minimum of 25
metres and maximum of 200 metres from a drill hole.
The MRE encompasses 3 mineralized massive sulphide lenses.
A total of 148 drill holes comprise the database including 2550 samples; of these 940 samples
were utilized in the estimate.
Grade capping was not utilized as it was noted that the general uniformity of grade was fairly
consistent with no significant outliers in the assay results.
The specific gravities used in the MRE were based on a total of 253 physically measured
specific gravities within the mineralized lenses.
Wolfden is not aware of any legal, political, environmental or other risks that could materially
affect the potential development of the mineral resources.
Exploration Target
Based on the current geological model, an exploration target for the Pickett Mtn. deposit is in the 8
to 10 million-tonne range at a grade of 12 to 20% ZnEq. This target is derived from the interpretation
of the drilling, surface geology and structure, as well as from sampling carried out in the locale of the
deposit. The potential quantity and grade of an exploration target are conceptual in nature. There
has been insufficient exploration to define a mineral resource of this size and it is uncertain if further
exploration will result in the exploration target being delineated as a mineral resource of this
magnitude.
Future Work
Exploration in 2019 will focus on the continued expansion and upgrading of the deposit that remains
open at depth and where folding may lead to the discovery of additional massive sulphide lenses.
Down-hole EM surveying will be utilized to assist in targeting possible extensions of the known and
recently discovered massive sulphide lenses. Additional testing of the recently discovered
footwall lens (north of the East Lens) and other regional targets could further expand the mineral
resource. In order to upgrade the inferred resource, a limited infill drill program with a
25 m
by
25 m
pattern is required to confirm if the current 50 by 50 meter drill pattern is sufficient.
Quality Assurance / Quality Control
Wolfden adheres to strict Quality Assurance and Quality Control protocols including routine insertion
of blanks and certified reference standards in each sample batch of drill core that is sent to the lab
for analyses. Drill core samples are split in half using a diamond saw with one half saved for
reference and the other half shipped via secure transport to Activation Laboratories sample
preparation facility in
Fredericton
, New Brunswick. Core samples are analyzed for zinc, lead and
copper utilizing sodium peroxide fusion, acid dissolution followed by ICP-OES (Code 8). Gold is
analyzed by fire assay (30 g) utilizing AA finish (Code 1A2) and samples with over 5 g/t are analyzed
by fire assay with gravimetric finish (Code 1A3). Silver is analyzed by fire assay with gravimetric
finish (Code 8-Ag).
