Vancouver, British Columbia--(Newsfile Corp. - September 12, 2022) - BAROYECA GOLD & SILVER INC. (TSXV: BGS) (the "Company") is pleased to announce it continues with exploratory tunneling and simultaneous bulk-sampling at the Santa Barbara Gold Project in Bolivar, Colombia. A second batch of 15,000 kg of mineralized vein material has been processed through the pilot processing plant.

Exploratory drifting continued following vein #1 from the crosscut towards the Southwest for another 25 meters. The first samples were collected starting at 3 meters from the crosscut for safety purposes, and then at approximately 1.5-meter intervals when possible. The vein in this interval splits into two parallel veins (20cm wide for each of them) and care was taken to separate the vein material from the wallrock for the bulk sample testing process. The southernmost branch of the vein is labeled A and northernmost vein labeled B for reference (see Table 1). Vein A averages 17.08 g/t Au for a sampled length of 18.8 m and vein B averages 25.85 g/t Au over a sampled length of 19m for a combined weighed average of 21.42 g/t Au over 0.4m in the entire interval.

The cross-referenced 15 tonne bulk-sample was collected and processed using the procedure described further in the text. Assay results from the head-grade samples collected at regular intervals at the discharge point of the second ball mill and later homogenized returned 18.91 g/t Au.

Raul Sanabria, P.Geo., President of Baroyeca commented: "We continue advancing the Santa Barbara project while proving the exceptional continuity of high gold grades over 200 m along strike within a single vein and still open to the southwest. This clearly extrapolates to the other parallel veins already identified in this project. Our exploration tunnelling - bulk sampling approach is paying off as we are not facing any nugget effect or small narrow discrete ore shoots, but the opposite, well-defined veins with evenly distributed high gold grades over long distances. These kinds of gold-veins are well known in Colombia for their continuation at depth, and we will soon drill them to prove the full extent of the system."

The Company has almost completed clearing the road access to the Mariana Mine and access to the fresh vein at Level 2 by a horizontal drift located 40 meters to the northeast of the former access shaft and bulk sampling is expected to resume here in the short term.

Sample collection method

Bulk sample collection is designed and supervised by a Qualified Person for QA/QC purposes. Baroyeca continues with the same bulk sampling process methodology with batch samples of 15 tons after completing some improvements and upgrades at the pilot processing plant.

The mining method employed at the exploratory tunnels consisted of splitting the vein from the barren wall rock and separating and collecting vein material with a minimum of wall rock attached. The vein material from the tunnel was then bagged at the tunnel portal in woven plastic bags and individually weighed until an approximate nominal 10-to-15-ton batch sized sample was completed. Samples were then loaded in random order into a truck and taken to the Santa Barbara pilot gold processing plant. Once the batch was completed, the section of tunnel from where the sample was removed was surveyed and followed with channel sampling at 1-meter intervals.

At the plant site, sample bags were dumped in random order after passing through a first stage of crushing to 2-inch and a second stage of crushing to 0.5 inch size. Crushed material was then stored in a bin with a vibrating door that self-feeds the primary ball mill. Crushed material was then sent to the primary ball mill (>40% passing 150 mesh) and secondary ball mill (>60% passing 200 mesh) connecting with the three 15m3 cyanide leaching tanks where the pulp was agitated before adding reagents for homogenization purposes. The head sampling consists of taking a sample of approximately 500 gr at the drain of the second ball mill point every 40 min for 8 hours. Then the complete sample is homogenized and dryed. Lastly the sample is split into a 1kg sample that is bagged and sealed to be sent to SGS labs in Medellin for Au and Ag fire assay. The pilot plant does not have a gravity separation stage or flotation system therefore there was no loss of material in the process and the sample pulp reaching the cyanide leaching tanks was considered the entire sample, with the sample being homogenized.

2022 Santa Barbara Exploration Program update

Baroyeca's Mining Engineering Team continues working improving ground access to the Mariana mine and conducting underground tunnel upgrades to speed up access to the fresh (unaltered) part of the vein below the saprock boundary. Baroyeca will continue with the bulk sampling / channel sampling in this area of the project immediately west of the Pilot Processing Plant.


Rock samples are shipped by transport truck in sealed woven plastic bags to SGS sample preparation facility in Medellin, Colombia for sample preparation and analysis. SGS operate according to the guidelines set out in ISO/IEC Guide 25. Gold is determined by fire-assay fusion of a 50 g sub-sample with atomic absorption spectroscopy (AAS). Samples that return values >10 ppm gold from fire assay and AAS are determined by using fire assay and a gravimetric finish. Silver is analyzed by inductively-coupled plasma (ICP) atomic emission spectroscopy, following multi-acid digestion. Silver is determined by ore grade assay for samples that return >500 ppm.
