Summary table of mineral resources as estimated in 2018
Calculation criteria used:
-
o.Cut-off grade of 6.5 g/t Au. Some polygons under this cut-off grade were included to ensure the continuity of the zones,
-
o.Price per ounce of gold at US $ 1,225 (3 years average) and an exchange rate of US $ 1 = 1.20 Can $,
-
o.Maximum content: 60 g/t Au for core samples and 55 g/t Au for chip samples. A grade of 32 g/t Au was applied for the polygons generated by the 2013-2014 drilling.
-
o.Specific Gravity: 2.85 g/cm3 as used in previous resource estimates,
-
o.Resources were evaluated from diamond drill samples and face samples using the polygon method applied to inclined longitudinal sections,
-
o.The minimum true thickness of the veins is calculated from its dip; 1.6 metre for veins having more than 50? and 1.8 metres for those having less than 50?,
-
o.The vein content is determined by the drilling intersection and the content of the adjacent material to meet a minimum thickness of 1.6 or 1.8 metre,
-
o.One Troy ounce = 31.1035 grams. The metric system was used for these calculations (metres, tonnes and grams/tonne),
-
o.Calculated tonnes have been rounded to the nearest hundred. Differences in the calculation total are due to rounded figures as recommended by NI 43-101,
-
o.ICM definitions and guidelines were used for this resource calculation.

Quality Control and Reporting Protocols:
Considering the potential sources of errors that a laboratory may encounter in the context of large-scale sampling, Aurbec introduced a Quality Assurance and Quality Control (QA/QC) program in 2013-2014. This program consisted of 1) the use of a control laboratory (Agat) to verify the accuracy of pulps and rejects results, 2) the insertion of blanks to control the sources of contamination, 3) the insertion of pulps in renumbered core sample rejects whose gold content was known to evaluate the reproducibility of the results and finally 4) insertion of Rocklabs certified referenced material.
Core samples taken from diamond drill holes were split in two equal parts with a core splitter by Aurbec's employees. One half of the carrot was prepared to determine its gold content while the other half was kept in the core box. The whole core from definition drilling samples was analyzed at the mine's laboratory.
The reception and preparation of samples at the mine's laboratory was done according to the accepted standards of the industry. The steps of drying, grinding (80% passing 10 mesh), splitting and pulverization were followed to produce 200 grams of pulp of which 80% passes a 200-mesh screen. A pulp fraction weighing just under 15 grams (half assay-ton) was used to determine the gold content of each sample. Although this quantity of pulp is one-half that used in the industry (one assay-ton) for gold determination made during exploration programs, it is considered sufficient when used for mining sites given the large number of samples taken by producing mines. The analytical method consisted of pyro-analysis with an atomic absorption finish. The method has a detection limit of less than 0.01 g/t Au.
After having examined Aurbec's internal protocol for controlling analytical results and compared 588 pulps and rejects made by an accredited external laboratory (Agat), the author is of the opinion that the manipulation, sampling and analysis of core samples, as performed at the mine's laboratory, are consistent with current industry standards.
Moreover, considering that;
-
1.the gold mineralization of the VMS-type vein deposits (which includes the Sleeping Giant gold deposit) is, by its nature, distributed more homogeneously than the gold contained in the classical vein deposits (Rafini, 2015),
-
2.the validation work done by InnovExplo (Jourdain, 2013) from drillings carried out prior to 2013, in areas also targeted by the 2013-2014 drilling program, concluded that the drilling database was adequate and reliable,
-
3.The update of the diamond drillhole database was done by Mr. Denis Desjardins, a qualified geologist having an extensive experience of the Sleeping Giant geology.
The author, Jean-Pierre Berube, is of the opinion that the analytical results of the Sleeping Giant mine's laboratory can be used safely for this mineral resource estimate.
Conclusions of the report :
After having conducted a detailed review of all relevant information and completed the current mineral resource estimate, the author concludes the following:
-
?.Although very complex, the geological continuity and grades of the gold zones of the Sleeping Giant project have been demonstrated;
-
?.The Sleeping Giant project contains more than 22 mineralized zones spread over several levels;
-
?.With resources of 122,400 tonnes @ 14.3 g/t Au, the 785N zone ranks fifth among the major zones discovered so far after zones 3, 8, 20 and 30;
-
?.The extension of several mineralized zones has not been drilled so that it is possible to "rediscover" areas using existing access;
-
?.There are strong possibilities that a future diamond drilling program will promote inferred resources to the indicated category or to allow some known areas to extend laterally and at depth.
Recommendations:
For the reasons listed in his report, available on Sedar (www.sedar.com), Mr. Berube recommends a major program of underground exploration and evaluation including the rehabilitation of infrastructures, the excavation of the last segment of the ore pass, the excavation of approximately 2,200 metres of cross-cuts and drifts and a provision of $ 1.2 million for exploration and definition drilling. The global budget represents a total of $ 8.2 million which will be spread over a period of two (2) years.

Abcourt Mines Inc. is a gold producer and a Canadian exploration company with strategically located properties in northwestern Quebec, Canada.
In 2016, Abcourt acquired the Sleeping Giant mine located halfway between Amos and Matagami, in Abitibi, Quebec, in the territory covered by the Government of Quebec's Northern Plan. Abcourt is the sole owner of the Sleeping Giant property which consists of four (4) leases and forty (40) mineral titles. The Sleeping Giant mine has an operating mill that can process 700 to 750 tonnes of gold mineralization per day.
The Elder property contains gold resources and was the subject of a positive PEA study in 2012. Abcourt is currently focusing on the operation of the Elder Mine.
The Abcourt-Barvue property has mineral resources in silver and zinc (2014). A feasibility study was completed by Roche and Genivar in 2007 and an update is in progress.
