Capitan Announces Consolidation of 2.5km Silver Trend at Cruz De Plata Project, Durango Mexico

Vancouver, British Columbia--(Newsfile Corp. - December 6, 2022) - Capitan Mining Inc. (TSXV: CAPT) ("Capitan" or the "Company") is pleased to announce that it has executed an option agreement with Minera Fresnillo S. A. de C. V. (a wholly owned subsidiary of Fresnillo plc), to acquire a 100% interest for the mineral rights to a key property at the Cruz de Plata Project.


  • Acquisition of key property between known silver zones at Jesus Maria and San Rafael allows Capitan to consolidate and grow the Cruz de Plata Silver Project
  • High-Grade Silver trend on Capitan's 100% owned property now grows to +2.5km
  • Newly acquired property brings additional data, surface showings and high priority targets
  • 6 holes pending assay from Capitan's 2021-2022 drill campaign with results expected before year end
  • Capitan is currently completing an RC drill program which includes multiple targets at Cruz de Plata
  • Capitan mining is well funded for 2023 - Recently closed financing totaling C$3.2M in November. See Press Release November 2, 2022


The new property blocks comprise a strategic, 261.42-hectare area that allows for the creation of a contiguous property package from the Capitan Hill / Jesus Maria targets to the San Rafael target, at the Cruz de Plata project (see Figure 1).

Additionally, these new concessions provide additional exploration targets related to and including:

  • The on-strike extension of the Jesus Maria and JM North targets to the east and northeast
  • The San Rafael and El Tubo targets to the west and southwest
  • The El Refugio and Santa Teresa Veins

With this addition, the Cruz de Plata high-grade silver trend now covers a total strike length of approximately 2.5Km from JM South - recently identified underneath the Capitan gold zone - to the San Rafael zone.

The new blocks also contain significant surface exploration work, historic workings, and approximately 2,000 meters of historic drilling in five (5) diamond drill holes. These drillholes returned significant silver mineralization along the El Refugio target and at depth, which is interpreted to be the potential on-strike extension of the Jesus Maria Vein (see historic drillhole section below).

Terms of the Option agreement are as follows:

  1. 3-year Exploration agreement with option to acquire 100% interest in the Casco U, Exp.2/5-0386 block
  2. Total payable amount of USD$1.0M over the three-year period.
  3. 1% NSR which can be bought for a total of USD$1.0M up to 10 years from acquiring 100% of the rights
  4. No exploration expenditure commitment other than that needed to keep property in good standing

Alberto Orozco, CEO of Capitan Mining stated: "Consolidating the high-grade silver trend at Cruz de Plata has been one of our top priorities for Capitan Mining. We are pleased and very excited to announce that we have established a dominant land position in what we strongly believe will one day be recognized as a significant high-grade silver system in Durango, Mexico. In addition, this key property acquisition also brings additional data and targets that will allow us to demonstrate to market the potential scale at the Cruz de Plata silver system."

Historic Data : Casco U Block

Fresnillo has provided Capitan Mining with a database consisting of surface sampling, mapping, and approximately 2,000m of diamond core drilling which targeted the El Refugio Zone. The El Refugio zone consists of a series of historic, underground mine workings that extend over approximately 200m, which targeted high-grade silver mineralization. Diamond drilling carried out by Fresnillo between 2018 and 2020, returned encouraging results which successfully tested the El Refugio zone at depth, tracing it down to approximately 400m below surface.

Highlights from the historic drill program include:

  • 5.2m of 298.48 g/t Ageq in hole JEMA-01
  • 29m of 95.39 g/t Ageq including 1.3m of 572.48 g/t Ageq in hole JEMA-02
  • 6.3m of 118.74 g/t Ageq from hole JEMA-03
  • 11.9m of 66.6 g/t Ageq including 1.2m of 321.1 g/t Ageq from hole JEMA-05

All relevant QAQC, drill logs and assay data/certificates has been provided to Capitan mining, have been verified, and are presented in the table below.

Qualified Person & QA/QC:

The scientific and technical data contained in this news release pertaining to the Cruz de Plata Project was reviewed and approved by Marc Idziszek, P.Geo, a non-independent qualified person to Capitan Mining, who is responsible for ensuring that the technical information provided in this news release is accurate and who acts as a "qualified person" under National Instrument 43-101 Standards of Disclosure for Mineral Projects.

Capitan Mining Inc. has a Quality Assurance/Quality Control program that includes insertion and verification of control samples including standard reference material, blanks and duplicates consistent with industry standards.

RC drill samples from the Cruz de Plata Project are collected and split at the drill site using a Gilson Universal Splitter. The samples are stored in either plastic bags (dry) or micropore bags (wet) and secured with plastic zip-ties and then transported to the preparation laboratory of Bureau Veritas in the city of Durango, Durango. The sample pulps are then transported to the Bureau Veritas' laboratory in Vancouver, where they are assayed for gold by fire assay with atomic absorption finish (FA430 assay method code; 0.005 to 10 ppm detection limit). Samples over 10 ppm Au and over 100 ppm Ag are assayed with gravimetric finish (Assay code FA530). All samples are also assayed by ICP-ES (code AQ300) for a suite of 33 elements. Samples over 1% Pb an d/ or 1% Zn are assayed by Aqua regia Ore Grade ICP-ES (AQ 370).

Diamond drill-hole samples, drilled by Fresnillo, reported in this press release were assayed at SGS Labs for gold by fire assay with atomic absorption finish (GE_FAA515 assay method code; 0.005 to 10 ppm detection limit). Samples over 10 ppm Au and over 100 ppm Ag are assayed with gravimetric finish (Assay code GEO_FAG515). All samples are also assayed by ICP-ES (code GE_ICP40B) for a suite of 33 elements. Samples over 1%Pb and Zn are assayed by Aqua regia Ore Grade ICP-ES (GO_ICP90Q).

All summarized intervals reported in this press release were calculated using a 25 ppm Ag equivalent (AgEq) cut-off grade with AgEq considering Ag, Au, Pb and Zn and calculated as follows: AgEq = Ag g/t + (80x Au g/t) + (0.003 x Pb g/t) + (0.0037 x Zn g/t). Intervals contain no more than 3 metres of internal dilution. High grades have not been capped.
