SRG Increases Mineral Resource Estimate for its Lola Graphite Project by 54% - Graphitic carbon content in Measured and Indicated Resources increase by 201%
MONTREAL, June 18, 2018 /CNW Telbec/ - SRG Graphite Inc. (TSXV: SRG) ("SRG" or the "Company") is pleased to report an updated mineral resource estimate for its 100%-owned Lola graphite deposit located in the Republic of Guinea (the "2018 Mineral Resource Estimate"). The 2018 Mineral Resource Estimate represents an increase of 54% of In-situ Graphitic Carbon ('Cg') at a 3% cut-off grade since the publication of the maiden resource. In preparation for the next phase of development of the project, several boreholes were completed to increase measured and indicated resources from inferred resources. As such, measured and indicated resources increased from 224,118t to 676,900t of Cg content at a 3% cut-off-grade, an increase of 201%.
The 2018 Mineral Resource Estimate, prepared by Montreal-based Met-Chem, a division of DRA Americas Inc. ("Met-Chem/DRA"), includes a pit-constrained measured and indicated resource of 12.2 million tonnes ("Mt") grading 5.6% graphitic carbon Cg and an inferred resource of 2.1 Mt grading 6.1% Cg, using a cut-off grade of 3.0% Cg. Effective date of the estimate is June 14, 2018.
The 2018 Mineral Resource Estimate replaces the maiden mineral resource estimate which was reported by SRG on December 22, 2017, and subsequently included in a Technical Report completed by Met-Chem/DRA with an effective date of September 30, 2017. A NI 43-101 Technical Report will be filed on SEDAR within 45 days of this news release providing the details of this resource update. Figure 1 provides a map of the current drilling program. Completed boreholes, assay results pending and boreholes to be completed can be viewed on the map.
Resource Summary
The mineral resources are based on 395 boreholes for 12,086 meters ("m") drilled up to April 4, 2018. Since that time, an additional 162 diamond drill holes have been completed, for approximately 5,686 additional meters for a total of 17,954 meters. Assay results for these additional holes are pending. Drilling onsite is ongoing and an additional 3,000 meters of drilling are scheduled to take place in the second half of 2018.
The updated resource is established for the oxide profile of the deposit, from surface to a depth ranging between 20 and 50 meters, with an average thickness of 32 meters. The mineralization continues at depth within the fresh rock material, but drilling is stopped once fresh rock is reached. The area for the resources covers approximately 33% of the deposit's 3.2-square-kilometer surface area.
The estimate was prepared using a block model constrained with 3D wireframes of the principal mineralized domains. Values for graphitic carbon were interpolated using Ordinary Kriging (OK) interpolation methodologies on 10 × 10 × 2m blocks. As in the previous resource estimate, a preliminary open pit optimization algorithm was run on the estimated grade block model. Only mineralization contained within the preliminary pit shell has been included in the resource estimate. The base case mineral resource estimate is summarized in the following table at a cut-off grade of 3.0% Cg together with estimate sensitivities at 1.64% Cg and 5.0% Cg.
