The core samples were assayed for multi-element and important grades of Germanium were discovered during the analysis. It appears Germanium is not evenly distributed in all sectors and it may be related to zoning within mineralized zones associated to sphalerite (Zn) and other sulfides. Additional work is being done in order take the Germanium values into account in the mineral resources. Assays range from below detection limit 20 ppm with a maximum of 497ppm Ge in 1.5m sample.

- 1.15m at 6.76 g/t Gold in sample number IM26, breccia oriented NW-SE;
With these positive results, Maya took the decision to postpone the publication of the PEA on Boumadine. The Corporation started an additional diamond drilling program at the North and Imariren Zones. An additional 37 holes were drilled totalling 1840 meters. This additional drilling program aims to better understand the distribution of precious metals and to explore the vertical extensions of these exposed mineralized structures. Complete drill results of this campaign are pending and will be disclosed once received, compiled and verified. This will allow Maya to integrate all data collected and produce the first NI 43-101 mineral resources estimate on Boumadine including the Imariren and North zones.
The 2017-2018 First Phase Diamond Drilling Program
The 2017/2018 first phase drilling program consisted of 14 diamond drill holes totaling 3,158.2m. Five holes were drilled at the zone Centre totaling 1,490.4m. Four holes were drilled at Zone Tizi, totaling 530.2m. Five holes were drilled at zone South totaling 1,137.6m.
This drilling program ended in April 2018 and the main objectives were:
- Validation of the historical panels at zone Centre and zone South;
- Explore the vertical extensions of the mineralization at zone Tizi, Centre and South;
The holes were mainly drilled in Ignimbrite, Rhyodacite and Andesitic rocks with many massive pyrite zones. These rocks are affected by shear zones, veins and veinlets and intruded by hydrothermal breccia. Most holes intersected the mineralized zones with massive sulfides, mainly pyrite, sphalerite, galena and more or less chalcopyrite.
Sulphide mineralization consisting in massive pyrite accompanied by pyrrhotite and more or less arsenopyrite. The mineralization was massive and reached 28 meters of drill core. Some holes showed principal vein-type mineralization with sharp layering cross-cut by several networks and stockworks of secondary sulfide mineralization. Quartz veins/veinlets were observed in many drill holes surrounding the principal zones with massive sulfides. We also observed the presence of voids within the Ingnimbrite filled by sulphides cements preferentially at the upper limit with the porphyry contact. In addition, the results from the diamond drilling program showed a spatial relationship between the mineralization and structural interpretation of the high grade intercepts from all the historical database dipping a roughly subvertical and NNW trending.
The most important intervals of the 2017/2018 drilling program are listed below in Table 1.

|Hole Name||From||To||Length||Au g/t||Ag g/t||Zn %||Pb %||Au Eq g/t||Zone|
The assay results for a minimum interval of 1 meter. The core lengths reported are between 60% and 75% of true widths. The grades herein are reported as uncapped values. Gold equivalent in this release are calculated using Au Oz 1250 USD, Ag Oz at 15 USD, Zn 2450 USD per tonne and Pb 2168 USD per tonne.
A total of 482.2m core samples (totaling 617 core samples) were submitted to the independent laboratory ‘Analyse Development Minier S.A.R.L.’ (ADM) based in Marrakech (Morocco) for preparation and assaying.
Based on the positive results cited above Maya Gold and Silver decided to add four diamond drill holes (totaling 2671.1m; 251 core samples) to intersect the extension at depth of the mineralized sections in the three zones (Center, South and Tizi). The table below (Table 2) show the highlights.

*Note: The latest holes of the 2018 program are not surveyed with a DGPS yet, it is why they have the fixed 1142mZ elevation in the table, also note that several were drilled from the same set-up, the precise location will be disclosed once received and validated.
Drilling on the tailings
A total of 49 holes were drilled on the Boumâadine tailings using the AMS soil core sampler. A total of 34 holes were drilled on tailing TG1 totaling 70.53m and 15 holes were drilled on tailing TG2 totaling 116.10m. The main objective of the drilling program was the mineral resource estimation of the tailings. The table below shows the highlights.

Maya’s geologists started the first surface sampling program at Boumadine in April 2018. The sampling program was discussed during the site visit from GoldMinds Geoservices and covered a portion of Imariren and zone Nord.
The sampling program consisted of channel sampling (with saw) cross-cutting the exposed mineralized structures oriented E-W, NNE-SSW and NE-SW filled by quartz cements, barite and traces of lead and copper. Sample length represented the thickness of the mineralized veins and their location was determined using a hand held GPS.
The main objectives of this sampling program were:
- Complete historical works to cover areas with less geochemical information;
- Prospecting new areas following the mineralized structures trend;
- Identified new target with high-grade potential for the diamond drill program in progress at Boumâadine.
The table below (Table 4) shows the surface grab & Channel samples highlights and their localisation are shown in Figure 1.
Table 4: The highlights from the surface sampling results.
|Hole Name||Au ppm||Ag ppm||Zn ppm||Pb ppm||Cu ppm|
The geochemical survey covered the main mineralized zone at the Northern part of the property. The geochemical survey appears to be a very effective method and gives us a better understanding of the polymetallic deposit (related structures, the geological control and target identification for drilling to explore vertical extension).
The figure below shows the surface sample locations with Au value in g/t taken from the exposed structures.
Quality Control / Quality Assurance (QA/QC)
The direction and inclination of the diamond drillholes were oriented in a way to intersect the mineralized zones and avoid the openings (ancient mine drifts). Only one drillhole (B_17_06) intersects an opening at a depth of 86.9m large of 2.5m in South zone.
The core was logged and sampled by the geologists of Compagnie Minière Maya-Maroc sarl (CMMM). The samples were analyzed by the independent laboratory Analyse Development Minier S.A.R.L. The half core samples are crushed to have d80 passing 2mm and afterwards riffle split to have 100 grams which is pulverized to have a pulp d80 of 75 microns Multi acid digestion and Atomic Absorption reading. Fire assay is used for gold grade determination.
The majority of the standards and blanks are in line with expected results. Some blanks (three) and standards (four) were mislabelled and corrected later by the geologists.
