- Thirteen percent of the ounces are classified as Indicated
Resources.
VANCOUVER, Feb. 21, 2019 /CNW/ - Barsele Minerals
Corp. – (TSX-V: BME) ("Barsele") is pleased to
report that an independently verified Mineral Resource Estimate has
been completed for the purposes of the Company on the Barsele Gold
Project in Västerbottens Län, northern Sweden (the "Barsele Project"). The
study concludes that diamond drilling to date along the
Avan–Central–Skiråsen gold zones at a 0.50 g/t gold cut-off for a
pit constrained extraction mining method and a 1.50 g/t gold
cut-off for a bulk underground extraction mining method and a 1.80
g/t cut-off for a selective underground extraction mining method,
has in combination, outlined an Inferred Resource of 25,495,000
tonnes grading 2.54 g/t gold (2,086,000 ounces of contained gold)
and an Indicated Resource of 5,578,000 tonnes grading 1.81 g/t gold
(324,000 ounces of contained gold).

|
The estimate
encompasses 61 gold-bearing zones, each defined by individual
wireframes with a minimum true thickness of 2.0 metres and using
the
grade of the material when assayed, or a value of zero when not
assayed. The resource was estimated using Geovia GEMS
6.8

|
High-grade capping
supported by statistical analysis was carried out on assay data and
established on a per domain basis for gold (g/t Au): low-grade
mineralized envelope = 5.0 g/t Au, high-grade gold-bearing
zones: Skiråsen = 30.0 g/t Au, Central = 30.0 to
40.0 g/t Au, Avan = 20.0 g/t Au
|

|
Grade
interpolation was performed by Ordinary Kriging on 2.0 metres
composites from drill-hole intersections falling within the
mineralized zones in a
block model using a block size of 10.0 metres by 3.0 metres by 5.0
metres

Density values
were applied based on lithology. All mineralized zones were
assigned 2.73 g/cm3

The Mineral
Resource Estimate is categorized as Indicated and Inferred. The
Inferred mineral resource category is only defined with a minimum
of 2
drill-holes, within the areas where the drill spacing is less than
100 metres and shows reasonable geological and grade continuity.
The Indicated mineral
resource category is only defined with a minimum of 2 drill-holes,
within the areas where the drill spacing is less than 25 metres.
Clipping boundaries
were used for classification based on those
criteria.

The Mineral
Resource Estimate is reported for three cut-off grades depending on
the nature and depth of the mineral resource: 1) a pit
constrained
extraction mining method at a cut-off grade of 0.50 g/t Au, 2) a
bulk underground extraction mining method at a cut-off grade of
1.50 g/t Au (Bulk
Zones), and 3) a selective underground extraction mining method at
a cut-off grade of 1.80 g/t Au (High Grade Zones). The cut-off
grades were
calculated using the following parameters: mining cost = $US 35.00
to $US 45.00; processing cost = $US 15.00; G&A = $US 5.00 to
$US 8.00; refining
and selling costs = $US 10.00; gold price = $US 1,300.00; and
metallurgical recovery = 92.6 percent. The cut-off grades should be
re-evaluated in light
of future prevailing market conditions (metal prices, exchange
rates, mining costs etc.)

The number of
metric tonnes were rounded to the nearest thousand, following the
recommendations in NI 43-101 and any discrepancies in the
totals
are due to rounding effects. The metal contents are presented in
troy ounces (tonnes x grade / 31.10348)

The exploration program at Barsele is being operated by joint
venture partner Agnico Eagle Mines Limited – (TSX, NYSE:
AEM) ("Agnico Eagle"). Ownership in the Barsele Project
is 55% Agnico Eagle and 45% Barsele. Agnico Eagle can earn an
additional 15% in the Barsele Project through the completion of a
pre-feasibility study. There is no cash outlay by Barsele until
pre-feasibility is completed.
"We continue to be pleased with exploration successes at
Barsele," states President, Gary
Cope. "The updated 2019 Mineral Resource Estimate for the
Avan–Central–Skiråsen zones, now incorporates cut-off grades for
pit constrained, bulk underground and selective underground
extraction mining methods, depending on the nature and depth of the
mineral resource. The 2018 exploration and resource modeling has
resulted in a significant upgrade in gold ounces, while maintaining
compelling gold grades. The 8.0-kilometer gold-bearing structural
corridor remains open in all directions for future
exploration."
The Independent and Qualified Persons for the Mineral Resource
Estimate, as defined by NI 43‑101, are Harold Brisson, P.Eng. and Carl Pelletier, P.Geo., both from InnovExplo
Inc. Both Brisson and Pelletier are qualified persons and
are independent of both Barsele and Agnico Eagle, based on the
requirements outlined in NI 43-101. The reported mineral resources
are not mineral reserves, as they do not have demonstrated economic
viability. The effective date of the Mineral Resource Estimate is
February 14, 2019.
The deposit model has been created by Agnico Eagle and that same
wireframe model has been accepted as is by InnovExplo Inc. The
mineral resource estimate follows current CIM definitions and
guidelines for mineral resources. The results are presented
undiluted and are considered to have reasonable prospects for
eventual economic extraction.
The resource estimate encompasses 61 gold-bearing zones, each
defined by individual wireframes, with a minimum true thickness of
2.0 metres and using the grade of the material when assayed, or a

Inferred. The Inferred mineral resource category is only defined
with a minimum of 2 drill-holes, within the areas where the drill
spacing is less than 100 metres and shows reasonable geological and
grade continuity. The Indicated mineral resource category is only

cut-off grade of 1.50 g/t Au (Bulk Zones), and 3) a selective
underground extraction mining method at a cut-off grade of 1.80 g/t
Au (High Grade Zones).
The cut-off grades were calculated using the following
parameters: mining cost = $US 35.00
to $US 45.00; processing cost =
$US 15.00; G&A = $US 5.00 to $US
8.00; refining and selling costs = $US 10.00; gold price = $US 1,300.00; and metallurgical recovery = 92.6
percent. The cut-off grades should be re-evaluated in light of
future prevailing market conditions (metal prices, exchange rates,
mining costs etc.).
The independent qualified persons for the Mineral Resource
Estimate are of the opinion that ongoing drilling will have a
positive impact on grade and tonnage distribution, upgrade parts of
the Inferred Resources into Indicated Resources and potentially
increase the overall Mineral Resource of the project.
Technical information in this news release was discussed during
a due diligence visit to the project site October 29-31, 2018, by Carl Pelletier of InnovExplo and the Barsele
Minerals Corp., Qualified Person and Agnico Eagle site management
and technical staff. Subsequently meetings were carried out between
Agnico Eagle and InnovExplo Inc. resource personnel in Val d'Or, Quebec.
Samples referred to in this news release were tested at
independent ALS Laboratories in Romania and Ireland, using ultra trace level method
(ME-MS61)-48 element by using four acid digestion together with
ICP-AES and ICP-MS analytical methods. Gold is tested by fire
assay, aqua regia digestion and analysed with an atomic absorption
spectroscopy (AAS) or gravimetric finish depending on grade
(Au-AA24 and Au-GRA22). Each method has a lower and upper
calibration range for which results are accurately determined. The
quality control/quality assurance program at the Barsele Project is
described on the Company's website at

About the Barsele Gold Project
The Barsele Project is located on the western end of the
Proterozoic "Skellefte Trend", a prolific volcanogenic massive
sulphide deposits belt, that intersects with the "Gold Line" in
Northern Sweden. Both polymetallic
deposits and intrusive hosted orogenic gold deposits are present in
this region and on the property. Current and past producers in the
region include Boliden, Kristineberg, Bjorkdal, Svartliden and
Storliden.
The Avan–Central–Skiråsen gold deposit remains open in all
directions. These structurally-linked mineralized zones occur
within granodiorite-volcanic-sedimentary host rocks that vary in
width from 10's of meters to 500 meters and have been encountered
over a distance exceeding 8.0 kilometers. Gold is generally
associated with arsenopyrite and low base metal content, but also
occurs as native metal.
