The La Zarza deposit was exploited by open-pit and inland mining for the extraction of crude pyrite, which was transported by rail to the port of Corrales, in Huelva, where it was shipped to various sulphuric acid production centres.
\n
\nThe mining operation began in the middle of the 19th century and ceased its activity in 1991, having produced more than 38 Mt of pyrite. Since then, there have been several investigations aimed at researching a type of mineral called \"silicate\" which, unlike the \"massive\" mineral, was not exploited, and the reopening of the activity, with a view to processing metals such as gold and copper. The most important of these are those carried out by the company Ormonde Espa\u00f1a in the period 2004-2012, in which they defined, through drilling research, mineral resources with more than 11 Mt in the JORC category with interesting Cu and Au contents, particularly in the silicate type of ore, also opening the door to the expansion of these resources in the massive ore, with relevant zinc and copper contents.<\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

In 2023, the second borehole investigation phase was completed with 13 new boreholes (6383 m in total), point load tests (585 tests) and densimetry (467 samples) and sampling for analysis (2346 samples).

\nThe drill cores, in the different campaigns, have been witnessed and photographed with a high resolution camera, prior to their geological and geotechnical witnessing and the sampling and execution of the different tests.
\nFive of the boreholes were investigated with acoustic and other multi-parameter probes.
\n
\n\nWith this investigation, the consultancy CSA-Global has defined resources in the JORC category of 107 Mt for the deposit, of which 63% would correspond to the Measured+Indicted Resources category.

\nIn addition, it considers 21.6 Mt of potential resources, which are not included in the JORC category, as they need further investigation.

\nWith the ore obtained from the drill holes, a sample composed of the massive ore and another of the silicate-type ore has been prepared for metallurgical tests to complement those carried out in the past by the Ormonde company. The results of the studies are expected in 2024-2025. With these results, the pre-feasibility study of the deposit can be undertaken.

\nIn pursuit of the extension of known mineralisation and the discovery of new masses, the study of geophysical anomalies is progressing, taking into account both proprietary and historical information, in order to define possible mineral extensions and new exploration targets.<\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
