Santa Barbara

The Santa Barbara Project is comprised of 110.86 hectares strategically located in the core of a prolific gold on the northern tip of the Serranía de San Lucas, also known as the “richest gold belt” in Colombia. It is surrounded by numerous active small-scale mining operations and artisanal miners, indicating the richness of the district.

  • The property sits next to the Pueblito Mejia’s Special Reserve Area of Mining (ARE) declared by the ANM (Agencia Nacional de Mineria (Colombian National Mining Agency)) in 2012.
  • Surface samples collected by a QP in 2018 returned up to 27.81 g/t Au, and several above 10 gpt Au (>0.30 Oz Ton Au).
  • Channel samples collected in July 2020 from the Santa Barbara exploration tunnel returned gold values as high as 102.42, 55.20, 49.83, 29.14, 26.81, all of them averaging 38.91gpt Au.
  • Currently conducting underground development on the Santa Barbara Vein by means of an exploratory tunnel and a cross cut to access more parallel vein sets.
  • Bulk sampling processing is currently being undertaken and over 450 tons of high-grade vein material has been processed at the Pilot Processing Plant returning average gold recoveries of >19 g/t /Au, and achieving >98% gold purity.
  • In total, more than USD$1.5M has been invested since 2015 by previous Canadian partners/operators for acquisitions, permitting, compliance, infrastructure and mine development.
  • The Santa Barbara Gold Project (Mining Title IEV16061C2) covers 100 strategic and road accessible hectares in Bolivar Department of northern Colombia, located approximately 300 Km North of Bucaramanga, the capital city of Santander Department.
  • At least 8 parallel vein systems have been identified on the property with the current exploratory tunnel centered on the Santa Barbara Vein system. The bulk of the identified vein sets measure several hundred meters of vein strike falling within the property boundaries.
  • Extensive numbers of prospecting pits and adits over gold mineralized veins within the property boundaries related to the prior activities of artisanal miners reveal the exceptional potential for gold mineralization on the property. All of these historical indicators are now georeferenced and have been systematically sampled by an independent qualified person (QP).
  • There is ample access to existing infrastructure, including roads, electric power, water and communications. The main road that connects Rio Viejo with San Martin de Loba-Barranco de Loba passes through the property on its easternmost side. All associated mining services can be sourced from nearby Aguachica town (Cesar department). Hospital, Police Station and basic infrastructure is provided in the nearby towns of Rio Viejo and San Martín de Loba.
  • A network of private and exclusive roads were built by the company to give access to the processing plant, camp and mine sites.
  • Newly built (2017) fully serviced permanent construction camp.
  • Own power supply (Diesel). Power grid 1km away from plant site.
  • Pilot Processing Plant (Bulk Sampling facility) fully operational for 30 tpd.
  • Crushing/milling capacity over-dimensioned for >100 tpd.
  • Compliance with health and safety, environmental and mining standards. All permits to operate in place and current.
  • Possibility of side production from Toll Milling.

santa barbara overview

The principal exploration target is an orogenic, vein-type gold deposit hosted in the Precambrian, Chibcha terrane gneisses, modified intrusions, younger Proterozoic and Palaeozoic age sediments largely belonging to the San Lucas formation that underlie the property. There are also younger Jurassic volcanic rocks and derived sediments. A lesser proportion of the gneisses is comprised of amphibolitic, hornblende gneissic and granodioritic gneissic rocks.

The veins in the property are 340° to 020° striking and West, East or vertical dipping pinch and swell veins. They follow parallel NE-SW trends typically, in this type of environment, are localized along splays off the main fault zone, along Riedel shears and bends, tension gashes within the main fault zone, or at points where the main fault zone is intersected by oblique angled faults.

They are comprised mainly of variable amounts of pyrite, sphalerite, galena, chalcopyrite and gold in a gangue of quartz and carbonate. These are hosted within gneisses and intrusions and based on preliminary evidence, may continue vertically into Phanerozoic volcaniclastic sediments.

In 2018, seven gold-bearing veins were examined and sampled, and several more were discovered during successive property visits. Based on personal observations of mineralised exposures, artisanal diggings/pits, tunnels and adits, individual veins have estimated minimum observed lengths of 50 metres up to 400 metres. They are generally parallel, with azimuthal trends from 030o to 060o, and overall steep to sub-vertical dips, generally from NW 60o to 85o. Vein widths may reach 0.5 metres, e.g. at Esperanza-Bonanza. Associated alteration is typically characterised by chlorite+/-carbonate+/-argillic minerals +/- sulphide mineralisation. Alteration widths may range from several cm to almost a metre.

Without systematic exposure of the veins, it is difficult to determine width (and grade continuity) of any one vein. Veining does pinch and swell, which is a normal phenomenon for the area, and in some cases, splits or branchiates.

In June, 2020, 10 channel samples were collected under remote supervision by R. Sanabria with a local geologist in representative areas of the vein.

The tunnel mapping and sampling notes the variability of gold values in punctual locations along the vein, ranging from 102.42 g/t Au in the higher end to 15.74 g/t Au in the lowest end. The vein ranges between 10cm and 35cm wide, locally blowing up to 50cm in width. Vein is characterized by a gangue of quartz, and minor carbonates (Calcite, Mn-Calcite), chlorite and sericite. Sulphides range from 10% to almost 80%, with pyrite being the dominant sulphide (>50% of the total sulphide content)) with variable amounts of galena, sphalerite and chalcopyrite. Gold to sulphides ratio seems to be conspicuous along the entirety of the vein.

The vein material extracted during 2019 and 2020 was part of a large bulk sample from part of the previous project evaluation plans that the operator Malabar Gold Corp./Sociedad Minera Malabar SAS had designed under the supervision of Raul Sanabria, P. Geo.

The exploratory tunnel was designed to enable blasting and splitting of the vein from the waste host rock for subsequent collection and pre-concentration of higher grade material at the mine portal. This material is then bagged, with each bag being weighed until an approximate 10 Ton batch is completed. The batch is then run through a crushing and milling circuit to a cyanide leaching tank. There are no losses of material in the circuit. The pulp is homogenized and a head sample is taken from the tank before being washed to remove clays and oxides prior to cyanide leaching. This sample can be considered representative of a head grade. Gold is precipitated by agitation adding zinc powder and smelted for every batch individually. Head grade assay results are cross referenced with gold pours to determine efficiency in plant recoveries as part of the metallurgical testing and to facilitate future improvements of the processing plant to increase processing capacity.

Processing methods are currently producing gold recoveries of over 90% with >98% gold purity.

Exploration activities proposed for 2021 will consist of structural mapping, soil geochemical surveys and IP surveys followed by trenching on anomalous areas directed to confirm the extent and number of veins present on the property, their widths, structural controls, ore shoot characteristics, geochemistry and alteration. The collected data will be used to better define drill targets for an approximate 5,000 meter drill program during Q3-Q4 2021 extending into 2022.

Exploration by means of tunneling will continue in parallel vein sets to the north of the Santa Barbara vein, as well as near the northern boundary of the project, opening new adits and accessing more veins while completing bulk sampling and trial mining activities. The revenues produced from this trial mining work will assist the company in funding exploration work as well as cover much of the overhead at the project site.

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.
