Leagold Reports High Grade Drill Results at Guadalupe Open Pit and Los Filos Underground

2019-09-13 / @newswire

 

VANCOUVER, Sept. 12, 2019 /CNW/ - Leagold Mining Corporation (TSX:LMC; OTCQX:LMCNF) ("Leagold" or the "Company") reports drilling results from the Los Filos underground and the Guadalupe open pit at the Los Filos mine complex in Mexico. Highlights from the Los Filos underground mine include 8.86 grams per tonne (gpt) over 27.45 metres and 6.59 gpt over 15.46 metres. Highlights from the Guadalupe area include 1.40 gpt over 32.73 metres, including 7.71 gpt over 2.67 metres, and 6.20 gpt over 10.61 metres, including 10.55 gpt over 5.20 metres (all capped grades and true widths; see Tables 1 to 3).

Leagold Mining Corporation (CNW Group/Leagold Mining Corporation)

Leagold CEO Neil Woodyer stated: "These drill programs at Los Filos will contribute to the reserve base and extend the mine life. At the Los Filos underground mine, we have encountered a new zone of mineralization and have confidence of adding this to reserves.

"At Guadalupe, we are testing for extensions of the mineralization at depth and also confirming the limited nature of old underground workings prior to open pit mining in this area.

"The mine expansion program is now under way and stripping at the Guadalupe open pit will begin in October. The Guadalupe open pit, with reserve grades of 1.37 gpt, provides high margin ore for our near-term production schedule. These initial exploration results are demonstrating that Guadalupe also has significant growth potential."

Los Filos Underground Step-Out Drilling

The Los Filos underground drilling program totals 12,750 metres in 55 holes for $3M. The objective of the program is to add to reserves and extend the mine life for this important high-grade ore source at Los Filos. The program began in July and is expected to be complete by the end of Q1 2020.

The program targets areas of mineralization close to existing underground workings that have a high probability of adding to mineral resources and reserves. Four holes have been completed and assays were received for two, and composites are shown in Table 1. These holes are a follow-up to previous exploration holes that identified an additional mineralized zone, the Encino zone, located east of the current workings (see Table 2).

Guadalupe Drilling

The Guadalupe drilling program totals 22,940 metres in 130 holes for $4M. The program began in July and is expected to be completed by the end of Q1 2020. Four holes have been completed, and assays from two have been received, and composites are shown in Table 3 below.

The drilling program at Guadalupe is an opportunity to evaluate several areas that have potential for high-grade mineralization and also to confirm broad widths of lower grade mineralization that are currently classified as Inferred and are being treated as waste in the open pit mining schedule. Leagold has identified several areas to upgrade Inferred to Indicated resources which may result in a reduction of the strip ratio. The program is also designed to test the extension of mineralization at depth and to confirm the limited extent of old underground workings prior to open pit mining in this area. Drilling to date confirms that the underground workings are narrow and are restricted to narrow high-grade intervals within the broader mineralized zone.

This program is expected to add to the reserve base and reduce the strip ratio in this area. In hole GOP-02-19, a new mineralized zone was encountered below the Guadalupe pit limit and this zone will continue to be tested during the drilling program.

The Guadalupe open pit proven and probable mineral reserve totals 34.5 million tonnes at 1.37 gpt containing 1.52 million ounces gold (refer to Appendix A for a breakdown into categories). The pit design also contains Inferred mineral resources of 17.5 Mt at 1.1 gpt with contained gold of 0.62 Moz gold.

The Guadalupe program also includes reverse circulation drilling in an area of skarn and intrusive that is only partially classified as Inferred resource. The opportunity is to enable additional material to be converted to resources and potentially be added to the reserve base.

Notes:

1.

CIM (2014) Definition Standards were followed for Mineral Reserves.

2.

Mineral Reserves used a gold price of US$1,200/oz; exchange rate of Mex$19:US$1.

3.

Tonnage and grade measurements are in metric units. Contained gold is reported as troy ounces.

4.

Mineral Reserves are stated in terms of delivered tonnes and grade, before process recovery. The exception is leach pad inventory, which is stated in terms of recoverable gold ounces.

5.

Mineral Reserves are quoted using a NSR break-even cut-off grade approach with minimum block NSR of $149.4/t for Bermejal underground. Cut-off grade for the Los Filos underground is 2.59 gpt. Mineral reserves for Los Filos, Bermejal and Guadalupe open pits are based on variable break-even cut-offs for ore revenue as generated by process destination and recoveries. Variables for revenue calculation include process cost, recovery, and estimated gold, copper and sulphur grades. Allowances for external dilution and mining recovery are applied.

6.

Details of cut-off grades, bulk densities, mining widths, dilution, mining factors and process recovery assumptions applied to Mineral Reserves and Mineral Resources are provided in the "Independent Technical Report for the Los Filos Mine Complex, Mexico" by SRK Consulting (Canada) Inc., and dated March 11, 2019 with an effective date of October 31, 2018.
