Mineral Resource
Estimate Footnotes:
|
1.
|
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., and the
effective date of the Mineral Resource Estimate is February 21,
2019.
|
2.
|
These mineral
resources are not mineral reserves, as they do not have
demonstrated economic viability.
|
3.
|
The mineral
resource estimate follows current CIM definitions and guidelines
for mineral
resources.
|
4.
|
The results are
presented undiluted and are considered to have reasonable
prospects for eventual economic extraction.
|
5.
|
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.
|
6.
|
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.
|
7.
|
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.
|
8.
|
Density values
were applied based on lithology. All mineralized zones were
assigned 2.73 g/cm3.
|
9.
|
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.
|
10.
|
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).

InnovExplo Inc. is
not aware of any known environmental, permitting, legal,
title-related, taxation, socio-political, or marketing issues, or
any other relevant issue not reported in the Technical Report, that
could materially affect the Mineral Resource
Estimate.
|
In addition to the Mineral Resource Estimate, the Report
discusses an Exploration Target. Following a detailed review of all
pertinent information, InnovExplo Inc., concluded that there are
several opportunities to add additional mineral resources by
drilling the depth extensions of the ore shoots that originate in
the resource area and the lateral extensions of the currently
identified zones. At this stage it is reasonable to believe that
somewhere between 6 and 12 million tonnes at grades between 1.5 and
2.5 g/t gold may be added by drilling extensions of currently
defined mineralized zones at depth and laterally. The reader should
be cautioned that this Exploration Target is not a mineral resource
estimate and is conceptual in nature. There has been insufficient
exploration to define this as a mineral resource, and it is
uncertain if further exploration will result in the Exploration
Target being delineated as a mineral resource.
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.
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.
For the Mineral Resource Estimate, the database used by
InnovExplo Inc., incorporated 779 surface drill holes. Only 544
drill holes were considered toward production of this Independent
Mineral Resource Estimate. The remaining holes were not included
for various reasons (either no confidence in the drill hole collar
location, or drill hole orientation, or suspect analytical results,
or the drill holes were outside the coherent resource study area).
Those 349 drill holes intersecting the mineralized zones and
producing the final resource database represent a total of 174,595
metres of drilling that took place at the Barsele Project from 1989
through November 2018.
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
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 and 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 a density
of 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 (Open Pits), 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 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 Inc., 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.
