Excellon Resources Inc.: Updates Platosa Mineral Resource Estimate

26.07.2018  |  CNW
TORONTO, July 26, 2018 - Excellon Resources Inc. (TSX:EXN), (TSX:EXN.WT), and (TSX:EXN.WT.A); (OTC:EXLLF) ("Excellon" or the "Company") is pleased to announce an updated Mineral Resource Estimate ("MRE") for the Platosa Mine in Durango, Mexico as at March 31, 2018.

2018 MRE Highlights

  • Updated MRE includes 17,120 metres of additional surface and underground drilling completed in the resource area from August 2016 to March 31, 2018.
  • Indicated Resource of 485,000 tonnes at 1,055 g/t silver equivalent ("AgEq") representing 16,456,000  AgEq ounces
  • Definition and expansion drilling continues from underground

"We have increased tonnage at Platosa despite mining approximately 170,000 tonnes since the last resource estimate as at December 31, 2014," stated Brendan Cahill, President and CEO. "This new resource estimate is the product of a more conservative and geologically accurate methodology than previously employed at Platosa. We see upside potential on grade and tonnage as we continue to define new mineralization with our underground drilling program."

Resource Summary for Platosa

The MRE will be included in an updated technical report prepared by SRK Consulting (Canada) Inc. ("SRK") under National Instrument 43-101 ("NI 43-101"), which will be available on SEDAR (www.sedar.com) within 45 days of this news release.

Notes:
(1) Mineral Resources are estimated pursuant to NI 43-101 with an effective date of March 31, 2018.
(2) Mineral Resources are estimated at a cut off grade of 375 g/t AgEq and silver, lead and zinc prices of $17.00, $1.10 and $1.30,  and assuming metal recoveries of 89% for silver and 81% for lead and zinc respectively.
(3) This MRE was prepared under the supervision of Sébastien Bernier, Principal Resource Geologist at SRK Consulting (Canada). Mr. Bernier is a Qualified Person as defined in NI 43-101.
(4) All figures have been rounded to reflect the relative accuracy of the estimates.
(5) Mineral Resources that are not Mineral Reserves do not necessarily demonstrate economic viability. The Mineral Resources reported herein have been estimated using a geostatistical block modelling approach informed from silver, lead and zinc assay data collected in core borehole samples. The construction of the Mineral Resource model was a collaborative effort between Excellon and SRK personnel. The construction and methodology for the creation of the resource wireframes was overseen by Blair Hrabi of SRK, P.Geo. (APGO #1723) and geostatistical analysis, variography, mineral resource evaluation and classification were undertaken by Sébastien Bernier of SRK, P.Geo. (APGO #1847). All technical work was reviewed by Ben Pullinger, SVP Geology of Excellon (APGO #2420).

This model incorporates enhancements and additional technical information not included in previous mineral resource estimates. These include the integration of structural studies completed in 2017, re-interpretation of the geology and mineralization of the Platosa deposit, and re-logging of mineralized intersections within the resource area. The revised wireframes provide a more representative, geologically correct and structurally constrained model, including significant improvements to the input data allowing for de-risking of future mining.

SRK has worked with the Company to review the geological model and independently estimated and reported the MRE for Platosa. The geological model was developed internally by the Company and reviewed by SRK. Individual mantos in the Platosa deposit were modelled using Leapfrog software by creating explicit wireframes interpolated from hanging wall and footwall contacts using the lithological and mineralization logs. A subset was confirmed by reviewing core photographs, and verified by re-logging core. The mineralized zone is distinctly bound by hanging and footwall contacts; generally sharp, replacement-style contacts, which are faulted and offset along the main structural features and post-mineralized faults, as modelled by the Company and SRK. The MRE is supported by a database containing 207,400 metres of drilling, including 17,120 metres drilled by the Company into the mineral resource area from underground and surface since 2016.

The evaluation of the MRE at Platosa involved the following:

  • Compilation of and verification of the drill hole database;
  • Generation of three-dimensional geological shapes and wireframes for mineralization, major structures and post-mineral faulting;
  • Statistical analysis derived from capping and compositing of raw data;
  • Block modelling and grade estimation for the manto shapes;
  • Application of a "cut-off grade" based on existing operational numbers at the mine; and
  • Preparation of a mineral resource statement.

For further detail please refer to technical report to be filed on Sedar.

The MRE was prepared in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum's (CIM) 'Mineral Resources and Mineral Reserves Best Practices' guidelines (November 2003) and is classified per the CIM 'Definition Standards for Mineral Resources and Mineral Reserves' (May 2014).

Exploration Update

Exploration at Platosa is ongoing, with two diamond drill rigs testing additional near mine targets in the Platosa Corridor to the north and west of the mine. Drilling is expected to continue throughout the year with regional targets such as Jaboncillo and San Gilberto being evaluated for drill testing.

In the second quarter of 2018, the Company completed significant exploration work at Jaboncillo including, detailed mapping, surface sampling and an initial 3D induced polarization survey. This target hosts numerous anomalous geochemistry samples thought to be indicative of the expression of alteration and mineralization seen at the edges of a replacement system. This program will be used to aid in structural modeling and targeting for future drilling.

The Company expects to release Q2 2018 financial results prior to market open on July 30, 2018.

Qualified Person

Mr. Ben Pullinger, P. Geo., Senior Vice President Geology, has acted as the Qualified Person, as defined in NI 43-101, with respect to the disclosure of the scientific and technical information contained in this press release.
