Power Ore Releases a Comprehensive Review
of the Potential of Disseminated Mineralization
at Opemiska Copper Complex
TORONTO

March 12, 2019
/CNW/ - PowerOre Inc. ("Power Ore" or the "Company") (TSX.V:
PORE) is pleased to announce that its ongoing compilation of historical drill results and 3D modelling
of the Springer and Perry mine geology is highlighting a large number of wide (defined as 20 metres
or longer) disseminated mineralized drill intersections on the Springer mine. Figure 1 shows the
locations of the significant composite intervals and grade obtained in the drilling on the Springer Mine
and Tables 1 and 2 list the composite intervals for the Explorateurs et Innovateurs de Québec inc
("Ex-In") and
Falconbridge
mine data.
"In our
February 4
news release, we showed that sampling in the early decades of the mine focused
on high grade veins and that much of the low grade, disseminated copper mineralization in surface
and underground drilling was left unsampled. We are keen to evaluate this aspect of the historical
drilling as it pertains to our attempts at estimating an open-pitable resource on the Springer mine,"
said
Charles Beaudry
, M.Sc., PGeo and géo, Director and VP Exploration for Power Ore.

Implication for Resource Modelling on the Historical Springer Mine
These results are being used for planning purposes in designing Opemiska's upcoming drill program.
This drill program will be divided between identifying additional areas of broadly disseminated
mineralization which could be included in an eventual open pit-based mineral resource estimation and
a twin hole drill program to validate the mine assays. The automatically calculated composites will not
be used for any other purpose.
The results confirm that there is abundant disseminated mineralization on the edges of the glory hole
on #3 Vein and that wide disseminated mineralization has been confirmed in the vicinity of #0 Vein to
the north and near #4 Vein in the south. Elsewhere the Ex-In drilling intersected narrower zones but
often with very high grades in the crown pillars of the principal named veins. Our current 3D modelling
is striving to exactly define the veins and the mined out stopes in order to domain the veins for
interpolation purposes. The 3D modelling is being done using scanned 2D plans and sections from
the old mine and work is ongoing with Veins #1, #2 and #3 completed and the other veins expected to
be completed in the coming week.
Review of Disseminated Mineralization in Historical Drilling
The historical Falconbridge Mine and Ex-In diamond drilling database contains 14,516 drill holes
totaling 853,267 metres both on surface and underground with a total of 303,909 samples analysed
for copper (218,909 samples with more than trace value), 21% assayed for gold and 26% assayed
for silver. Occasionally, when visible cobalt mineralization was observed the core was assayed for
cobalt.
For the drilling undertaken by Ex-In, Power Ore manually compiled the composite mineralized intervals
over 20.0 metres in width. No lower assay cut off grade was used but composites were limited to
intervals above a nominal 0.5% average copper cut off grade. For the
Falconbridge
mine data we
used data mining techniques in this investigative phase of the project. To get a better sense of the
disseminated mineralization we carried out an automatic calculation of the composite intervals using a
top cut of 1% copper equivalent for any high grade samples (to reduce the influence of assays in
mined out stopes), and calculated an overall composite copper equivalent grade using a very low cut-
off at 0.05% copper-equivalent in order to ensure we generate the widest possible mineralized
interval irrespective of grade.
65 surface holes (out of 837 surface drill holes) returned composites over 20 metres in length with a
grade above 0.2% Copper Equivalent(*).
*We used Cu, Au and Ag price of US$2.65, US$1,274 and US$15.74, respectively.
Copper Equivalent ("Cu Eq.") grade including gold and silver based on 100% recoveries is
calculated using the following equation: Cu Eq. = [(Cu % * 20 * Cu price) + (Au gpt / 34.2857 x Au price per ounce) + (Ag gpt / 34.2857 x Ag price per ounce)] / (20 x Cu price).
About Opemiska Copper Mine Complex
The Opemiska Copper Complex is located adjacent to the town of
Chapais, Quebec
within the
Chibougamau
region. Opemiska is also within the Abitibi Greenstone belt and within the boundaries of
the Province of
Quebec's
Plan Nord which promotes and funds infrastructure and development of
natural resource projects. The project consists of 11 mining claims and covers the past producing
Springer & Perry mines which were owned and operated by
Falconbridge
. The project has excellent
in place infrastructure including a power station and direct access to Highway 113 and the Canadian
National Railway.
Opemiska was mined by
Falconbridge
as a high-grade underground mining operation and was in
production for over 35 years prior to Ex-In acquiring the property in 1993.
QP Statement and Note on Falconbridge Mine Assays
The technical information contained in this news release has been reviewed and approved by
Charles
Beaudry
, P.Geo and géo., Director and Vice President Exploration for Power Ore, who is a Qualified
Person as defined in "National Instrument 43-101, Standards of Disclosure for Mineral Projects."
With respect to the results from the drilling by Explorateurs et Innovateurs de Québec inc ('Ex-In') we
have all the original assay certificates and we have reviewed all the available QC results which
included standards, blanks and duplicates. All the pulps and rejects from all the Ex-In drilling are
available as well as all the core and we plan on resampling the pulps with rigorous QAQC protocols in
order to be able to use these drill results in any future resource estimation. Regarding the
Falconbridge Mine assays, none of the assays compiled from the
Falconbridge
historical mine drilling
have been validated at this time because of absence of any core left over from the mine operations.
However the sampling already done by Ex-In, which confirmed the copper grades in many areas of
the historical Springer mine they drilled as well as the records preserved from the old mine, including
annual grade reconciliations, give us the confidence to use the data « as is » until a proper validation
drilling campaign (up to 20 short diamond drill holes planned for May and June) can provide the basis
to validate all the mine assaying for initial resource estimation purposes. We are using these
historical assays for data mining purposes to help provide some constraints for the development of
our hypotheses concerning the Opemiska Copper Project and in particular the distribution of
disseminated mineralization, which was generally not mined in the underground operations.
