"With the acquisition of Algold now complete, we can focus on our Tijirit exploration and development efforts to immediately deliver value for shareholders. We have already increased M&I resources at Eleonore by 127%, and our team is mobilized to deliver a feasibility study within the next twelve months. We have several drill-ready targets generated by the first mineral resource since 2018. We look forward to leveraging our technical expertise and financial strength to unlock value for all stakeholders," said Benoit La Salle, President & CEO.
"The Tijirit Project has terrific potential and offers all the necessary conditions to create meaningful stakeholder value for the people in Mauritania in addition to benefitting further from the positive in-country foreign investment climate. We look forward to deepening our relations and local impact as we move Tijirit to the feasibility stage and beyond," said Thierry Vergnol, President & General Manager of TIREX S.A.
Aya paid a total consideration of C$15.2 million that comprised
The final exchange ratio is 0.010601 of an Aya common share for each Algold share. Algold shareholders will receive the resulting Aya shares without action on their part.
All Aya shares received in conjunction with this transaction are subject to a four-month hold period.
Mineral Resource Estimate
Table 1: Mineral Resource Estimate, Tijirit (1-11)
The resource estimate was prepared by SGS Canada Inc. Geological Services with an effective date of May 12, 2021, using results from 693 RC drill holes totalling 87,765 meters, 69 DDH holes totalling 9,289 meters, 97 RC/DDH holes totalling 16,727 meters and 20,243 meters of trenching carried out on the property by Algold between 2016 and 2018 and by previous operators Shield Mining and Gryphon Minerals from 2009 to 2012. Notwithstanding the increase in gold ounces of almost 73% in the M&I resource categories for Tijirit, no new NI 43-101 Technical Report will be released for Tijirit as the overall increase in total resources is considered non-material for the Corporation.
Launch of Tjirit Feasibility Study
Following the acquisition of Tijirit, Aya has launched a FS to assess the potential for developing Tijirit. The following globally recognised engineering consultants have been mandated to complete the FS: Lycopodium Minerals Canada, SGS Canada Inc., DRA Americas Inc., and GCIM.
The FS, which will initially focus on the Eleonore and Eleonore East deposits, is scheduled for completion within the next twelve months and envisages a base case scenario of a 1,000-tonne-per-day ("tpd") processing plant that can be easily expanded to 2,000 tpd. The proposed initial flowsheet will comprise a conventional primary crush and SAG milling circuit, followed by gravity gold recovery and leaching.
A budget estimate of $5.6 million has been established for the year in conjunction with Tijirit. The following activities will take place:
Resumption of Activities at Tijirit Camp
In February 2021, Aya re-opened the Tijirit exploration camp after a 1.5-year pause. Following some repair work, the exploration team returned to the camp in March 2021. Currently, a detailed mapping of artisanal mining excavations is being carried out involving a GPS survey, depth measurements, and sampling of excavated material.
As part of the 2021 field work campaign, Aya is in the process of securing the Eleonore and Eleonore East areas by digging a trench around the zones and filling excavations created by artisanal mining activity. Once the zones are secured, in coordination with the government, Aya will launch the 2021 drill exploration program and other field work (see Figures 2 and 3 in Appendix).
Increasing Potential of the Tijirit Project
The 127% increase in M&I resources validates Aya's geological interpretation of the Eleonore mineralization, in addition to highlighting the potential for additional ounces from targets that have only had limited exploration to date. Eleonore's multiple high-grade, shear-hosted mineralized zones remain open down-dip and along strike, with multiple areas in the immediate area still untested (see Figure 2 in Appendix).
The Eleonore East zone, which extends over a three-kilometer strike, is situated at approximately three kilometers northeast of Eleonore. The zone is believed to offer the potential for further high-grade discoveries within the mine lease that, with more drilling, could rapidly be included in future mining plans (see Figure 3 in Appendix).
Key Appointments – Tijirit Project
To lead the development of Tijirit, Aya has appointed Thierry Vergnol as President & General Manager of TIREX S.A. and recently engaged Patrick Pérez, MSc., P. Eng., as Project Director for Tijirit. A French-Mauritanian national, Thierry has been managing the Tijirit Project since 2017 and brings over 20 years of business advisory experience to international companies operating in Mauritania. Patrick has more than 18 years of experience as a mining professional including with Endeavour Mining, and DRA Americas.
Resource Estimation Methods
A modeling cut-off grade of 0.3 grams per tonne ("g/t") Au, a minimum thickness of two meters, and a minimum accumulation of 1.2 meters g/t were used to delineate mineralized volumes. The 2,973 two-meter composites were capped at grades varying between 3.5 g/t Au and 45 g/t Au based on local extreme grades. Only a few composites were capped, with the gold loss due to the capping at 12% for the base case resource. Densities are based on 5,628 readings from DDH holes. A density of 2.00 t/m³ was used for saprolite, and fresh rock was set to 2.7 t/m³ in the Lily zone, 2.8 t/m3 in the Sophie III zone, 2.85 t/m³ in the Sophie II zone, 3.0 t/m³ in the Sophie I zone, 2.86 t/m³ in the Eleonore North, Center and South zones and 2.95 t/m³ in the Eleonore East zone.
The block model has a block size of 2 x 5 x 2.5 meters for Sophie I-II-III and Eleonore; 2 x 5 x 2 meters for Eleonore East; 2 x 5 x 5 meters for Sophie III and 5 x 5 x 5 meters for Lily. With the exception of Lily, block models are turned to conform to the general orientation of the zones. Estimations were made by inverse distance squared with ellipsoid influenced distances. Kriging was also tested, and general results were very comparable. A total of 311 separate volumes were estimated with 311 composite sets. Two estimation passes were used with ellipsoids of 75 x 75 x 25 meters and 150 x 150 x 50 meters. The first pass uses a minimum of four and a maximum of seven composites, with a limit of two per drill hole. The second pass uses a minimum two and a maximum of seven composites with a limit of two per drill hole, except for some volumes with a minimum of one. The smoothing of the estimation was tested in May 2017 and was found to be adequate. The M&I categories have been outlined by hand on longitudinal, based on drilling density. Drilling every 40 meters (Eleonore North, Center, South and East and Sophie I), 45 meters (Sophie II-III) and 50 meters (Lily) was classified as indicated; and drilling every 30 meters (all except Lily) and 35 meters (Lily) was classified as measured. Eleonore has a maximum interpolation up to 100 meters. Other zones have interpolation up to 200 meters. All zones have extrapolation limited to 45 meters.
Optimized open pits have been prepared to allow to constrain the resource estimate. The assumptions include a gold price of US$1,500/oz., mining recovery of 95%, mining dilution of 5% (for Sophie/Lily) and 10% (for Eleonore), processing recovery of 96% (for Sophie/Lily) and 97% (for Eleonore), processing cost of $12.02/t, G&A cost of $3.69/t and an open-pit mining cost of $1.41/t. For underground mining costs, the current assumption is $40/t. Based on these assumptions, the economically viable cut-off grades are 0.4 g/t Au in open pits and 1.5 g/t Au under the pits. Accordingly, the Corporation decided to retain COGs of 0.4 g/t Au in open pits and 1.7 g/t Au for Sophie/Lily and a global COG of 1.5 g/t Au for Eleonore.
Quality Assurance / Quality Control (QA/QC)
Since the beginning of 2017, analytical work for drill core and reverse circulation chips, geochemical samples and rock chip samples has been carried out by the independent SGS Laboratories Ltd. ("SGS") in Bamako, Mali. The 50-gram fire assay with ASS finish analytical services are accredited by SANAS and are carried out with a quality assurance protocol in line with ISO 17025:2005. Prior to 2017, drill samples were prepared in the independent ALS Laboratory in Nouakchott, Mauritania and analysed at ALS Laboratories Ltd. in Loughrea, Co. Galway, Ireland, an ISO 17025 (2005) Certified Laboratory.
In 2016 and 2017, samples were stored at Algold's field camp and put into sealed bags until delivered by a geologist on behalf of Algold to the respective laboratory where samples were prepared and analyzed. As of August 2017, SGS established a mobile sample preparation facility in the Tijirit Camp. This preparation facility was run by SGS staff and used to prepare the majority of samples. Algold's samples were logged in the tracking system, weighed, dried, and finely crushed to better than 70%, passing a 2-mm (Tyler 9 mesh, US Std. No.10) screen. A split of 1,000 grams ("g") was taken and pulverized to better than 85%, passing a 75-micron (Tyler 200 mesh) screen, and a 50 g split was analyzed by fire assay with an AA finish. Selected samples were re-analyzed using a 1kg cyanide leach (Bottle Roll) using "LeachWELL" or a 1-kilogram ("kg") screen fire assay method. These results automatically superseded the original 50 g fire assay result. Under Algold's quality assurance and quality control (QA/QC) procedures, blanks, duplicates, and certified reference material (standards) were routinely inserted within the sample stream to monitor laboratory performance during the preparation and analysis. Once results were received, approximately 5% of the pulverised drill samples were randomly selected, given new sample numbers, and sent to an SGS Lakefield Laboratory for 50 g fire assay analysis. These umpire lab check assays were compared with primary laboratory results to monitor bias and accuracy of the Bamako facility.
