All exploration from 2012 to 2014 was carried out by Condor Precious Metals Inc. A series of Ag-(Au)-polymetallic veins were discovered by Condor geologists prospecting in the north-west corner of the property/ Vein exposures noted in creeks are predominantly ENE-WSW oriented, with sub-vertical dips, and hosted in dark grey weakly chloritic and/or chlorite-graphite schist within more quartz rich sediments.
Highest grades were obtained from sampling of the Veta Grande East, on the eastern side of Santa Agueda creek. A series of chip samples were taken in three exposures of the vein and individual samples returned gold values as high as 14.65 g/t Au and 1370 g/t Ag, 14.20 g/t Au, and highest silver values of 3,480, 2,300, 1,955 and 1,570 g/t Ag.
Veta NW is exposed in a tributary creek about 100m outside of the western side of the property boundary. Results from this outcrop are bonanza grade (up to 9 g/t Au and 1030 g/t Ag, 19.9 g/t Au and 311 g/t Ag, 7.10 g/t Au and 525 g/t Ag and 7.49 g/t Au and 178 g/t Ag) and the vein shows fragments at least 0.6m thick. The vein within the property boundaries is covered by a thick gravel deposit that prevented additional sampling.
Two parallel channel samples were taken of the Tavera vein, over an averaged 1.85 m interval, with 5.20 g/t Au and 66.78 g/t Ag returned. The best intersections were 0.4m at 14.8 g/t Au and 217 g/t Ag, 0.4m at 9.67 g/t Au and 80.6 g/t Ag, and 0.4m at 5.11 g/t Au and 151 g/t Ag. Individual samples taken at the Tavera zone returned gold values as high as 14.8, 9.67, 5.11 and 4.9 g/t Au, and 217, 151 and 97.1 g/t Ag.
There is a parallel vein set (Veta La Ye) with well-developed textures and mineralisation, located about 200m North, and exposed along the San Antonio creek. Preliminary channel sampling returned encouraging Au and Ag values. Two main exposures of the vein, the northeasternmost (Quebrada San Antonio), perhaps the best exposed, were channel sampled in three different locations along strike, and the second, located in a cornfield adjacent to Santa Agueda creek, was also sampled. Between the two, a third vein is exposed at a road crossing, hence its name, 'La Ye' (meaning 'crossing' in Colombian Spanish). Here, the vein appears folded, and cut by small scale, imbricated, North facing faults. The relationships between these faults and the mineralisation have yet to be fully determined, but they clearly postdate the mineralising event. Similar phenomena occur at El Dorado and La Platilla north of the town of Falan several km to the north.
Cumulatively, the three occurrences provide some indications of the various geometries within deformed veins and the host schists. Vein exposures display variable widths of between 0.5m and >2m, an average strike/dip of 040/60, and traceable for 420m. To the north-east, it is cut by a fault that parallels the upper part of the Socorro creek, immediately outside of the North boundary of the property. Host textures include quartz-chlorite-sulphide layering, brecciation, crack-seal and drusy textures. Two phase silica is readily apparent. Sulphide mineralisation is in the order of 5% with zones of massive sulphides. The main sulphide is pyrite, both fine grained and coarse (euhedral), with lesser to trace amounts of galena, sphalerite, minor chalcopyrite, silver sulphosalts and possible native silver. Several series of channel samples were taken from 'La Ye' vein and individual samples returned gold values as high as 2.09 g/t Au and 412 g/t Ag and 3.96 g/t Au and 141 g/t Ag. Channel 2 results were highest, returning 0.75 g/t Au and 128.67 g/t Ag over a 1.60m interval.
Veta Grande West (Veta La Esperanza) crops out in a tributary West of the Santa Agueda creek, about mid-slope. The vein is exposed for about 15m, has an average 0.5m to 1m thickness, is shallow dipping (45º), and quite weathered. Except for one sample returning 12.75 g/t Au and 74.30 g/t Ag, results were lower compared to other sampled locations. Fragments found downstream have good fresh textures and elevated sulphide content. There is another poor exposure along strike towards the West in a creek parallel to Santa Agueda, where float material has well-formed textures and mineralisation, and results returned ore grades.
BGS exploration work during 2020/2021 includes mapping and rock chip sampling, identification and surveying the portals of historic workings, and acquiring and compiling historic exploration results, such as underground mapping conducted by Condor Precious Metals at the Santa Ana colonial mines, Jimenez Creek mine, El Gran Porvenir, El Oasis, El Cirpe, Versercia among others to correctly understand controls to mineralization and geometry of high-grade shoots within the veins.
BGS identified two new vein zones named EL Erizo and Perrika in 2021, where rock ship samples returned silver values as high as 951, 839, and 691 g/t Ag for the first and 5.70 g/t Au and 696 g/t Ag and 6.91 g/t Au and 510 g/t Ag for the second. El Cucharo vein was also found in 2021 returning high gold values (17.59, 15.01 and 10.89 g/t Au) and 217.6, 187.2 and 168.t g/t Ag. Other veins found include several parallel sets to known veins, such as El Arroyo vein, the extension of the Tavera-Las Guaduas vein set at Santa Agueda creek, Veta blanca and several vein sets at the Jimenez Creek in the NE part of the property that are currently being evaluated and samples being sent to the lab for gold and silver assay results. The veins show an inferred strike length of at least 500m to >1,000m as inferred from outcrop, vein float and rubble, and historic workings.
Baroyeca Gold and Silver believes the Atocha project is the most prospective high-grade silver-gold exploration project in the Santa Ana-Frias-Mariquita historic colonial silver district, and that the project potential is significantly enhanced by the recently recognized high-grade gold zones in veins. Historic colonial mining records, and limited historic drilling and high values in rock samples all indicate exceptional potential for the Atocha project.
Exploration activities proposed for 2021 will consist of surface detailed structural mapping, trenching and soil geochemical sampling directed to gather further information to confirm the extent and number of veins present, their widths, structural controls, ore shoot characteristics, geochemistry and alteration. The collected data will be used to better define drill targets for an approximate 10,000 meter drill program during Q3-Q4 2021 extending into 2022.
Alongside this work, Baroyeca will work with the local communities and authorities to promote awareness of the project and promote inclusion of all stakeholders, fostering collaborative work that will generate mutual benefits for Baroyeca and the local communities.
