The new Technical Report is being prepared in accordance with National Instrument 43-101 (“NI 43-101”) and the CIM Standards by Mercator Geological Services Limited, with contributions which were made by P&E Mining Consultants Inc. with reference to the Mineral Reserve Estimate, mining and metallurgical engineering sections. This Technical Report will be filed on www.sedar.com within 45 days of this news release.
This Mineral Reserve and Resource Estimate marks the first compiled since Ascendant acquired the El Mochito mine in December 2016 and replaces the previous estimates with the effective date of December 31, 2015. The current Mineral Reserve Estimate is based on the completion of a life-of-mine plan that results from 46,100 metres of new exploration and definition drilling that was carried out in 2016 and 2017 as well as the reinterpretation of historical data, including of over 1.2 million metres of drilling.
The bulk of the Mineral Reserves are contained in the Esperanza, Palmar Dyke, Santa Elena, Santa Barbara, Santo Nino and Victoria zones, and where the Company is expected to produce from in 2018 into 2019, are shown below in both plan and cross section (Figures 1 & 2). With an additional 40,000 metre drill program planned at El Mochito in 2018, the company expects to further enhance the overall Mineral Resource base at the mine supporting a long operating life.
Chris Buncic, President and CEO of Ascendant commented: “We are very excited to be able to announce such a significant Mineral Reserve and Resource Estimate for the El Mochito mine. As we anticipated, our 2017 exploration success has demonstrated the potential upside and longevity of the mine and is a testament to the quality of the asset, reaffirming the mine’s long history of upgrading and defining new Mineral Resources through focused exploration. Based on current mining rates, a mine life beyond 7 years is indicated, and given the mine’s 70-year history, we would anticipate operating El Mochito long into the future.”
He continued “Historically, the El Mochito mine has achieved great success in converting Inferred Mineral Resources into the Measured and Indicated categories and this has been demonstrated once again with this latest Mineral Resource Estimate. Management therefore has the confidence that with further exploration work the Mineral Resources will continue to grow as we position El Mochito for the long-term. In the near-term, we remain focused on bringing up process plant feed grades to those seen in our Mineral Reserve Estimate.”
Mineral Reserve Estimate
The P&E Mining Consultants Inc. Mineral Reserve Estimate (Table 1) review strategy was based on a review and check for reasonableness of the ZnEq% (percent zinc equivalent) cut-off value. Subsequently, the internal dilution, external dilution, and mine extraction (mining recovery) was scrutinized for each of the four mining methods employed to ensure they fell within acceptable limits for Mineral Reserve Estimate reporting. In addition, the remaining Mineral Resource Estimate not converted to a Mineral Reserve Estimate was reviewed to ensure it balanced with the mine extraction data. The Mineral Reserve Estimate reviews were summarized into overall dilution and mine extraction percentile for a reasonable value comparison analysis. The average values are as follows: Internal Dilution = 1.2%, External Dilution = 14.3% and Mine Extraction = 90.8%.
Mineral Resource Estimate
The Mineral Resource Estimate, as set out in Table 2, was prepared by Mercator Geological Services Limited. The effective date of this Mineral Resource Estimate is January 1, 2018, and it is based on 26 contiguous areas of “manto” and/or “chimney” style skarn mineralization defined by 2,176 diamond drill holes up to December 31, 2017. 3D solid models of skarn mineralization reflecting a minimum grade of 3% ZnEq. were depleted for previously mined areas to constrain resource volumes. GEOVIA Surpac® 6.8.1 software was used to assign block grades for zinc (%), lead (%), silver (g/t) and density (g/cm3) for Measured, Indicated and Inferred Mineral Resources using inverse distance squared (ID2) interpolation methodology and capped 5 foot down hole assay composites. Up to four interpolation passes were applied using progressively increasing ellipsoid ranges to cover the range of 3D solid model sizes present. Block size is 10 feet (x) by 10 feet (y) by 10 feet (z) with two levels of sub-blocking allowed to a minimum block size of 2.5 feet (x) by 2.5 feet (y) by 2.5 feet (z). Resource categorization was applied using discrete solid models developed from contributing drill hole and assay composite parameters.

Quality Assurance and Quality Control
Prior to December 2008, quality assurance and quality control (QAQC) programs for drill core were implemented on a routine basis at the mine laboratory. This included use of blank and calibration materials plus analysis and monitoring of duplicate sample results. Subsequent to 2008 and prior to 2015, systematic insertion of additional blank samples was added along with periodic analysis of check samples at independent accredited commercial laboratories. Systematic insertion of certified reference materials was subsequently initiated. Since acquisition of the project in December 2016, Ascendant has introduced additional project-specific reference materials to the QAQC protocol, with core analysis being carried out by Bureau Veritas Commodities Canada Ltd. (ACME), in Vancouver, Canada, a fully accredited analytical services firm that operates internationally.
Drill core samples in 2017 and 2018 were prepared in Bureau Veritas’s laboratory in Guatemala City, Guatemala. Pulp samples were then sent to their analytical laboratory in Vancouver, Canada. All samples were analyzed for zinc, lead, copper, iron and silver values determined by method code AR402 atomic absorption spectrometry, and any over limit values were determined using method code FA410. Bureau Veritas has routine quality control procedures which ensure that every batch of 36 prepared samples includes three sample repeats, two commercial standards and blanks. Bureau Veritas is independent from Ascendant. Ascendant uses standard QA/QC procedures, and randomly includes five QAQC samples into every batch of 36 samples at an insertion rate of approximately one QAQC sample for every seven core samples.
