Soma Gold Announces Results of New Drilling Program on Extension of the Cordero-Balvina Mineralization






Soma Gold Corp. (TSX-V: SOMA) (WKN: A2P4DU) (formerly Para Resources Inc.) announced the results of the next phase of the ongoing drilling program to delineate the northern extension of the Cordero – Balvina mine on the El Bagre Project.


About the El Bagre mining project


The underground gold project is located 167km northeast of Medellin, in the department of Antioquia, within the jurisdiction of Zaragoza and El Bagre municipalities. The El Bagre underground gold operation includes the La Ye and Mangos gold mine and the Cordero-Balvina gold exploration project (see map #1).


Geology of the project


The La Ye, Mangos and Cordero-Balvina veins are hosted in shear zones with fragile-ductile deformation within carboniferous granite rocks of the El Carmen stock. Locally this plutonic body corresponds to a leucocratic tonalite, of medium to coarse grain and phaneritic texture, composed of quartz, plagioclase, amphibole, and biotite. Lode gold type mineralization trends north-northwest to north-northeast and consists of milky white quartz containing native gold and up to 20% mixed sulphides, dominated by pyrite with occasional galena, chalcopyrite and tellurides. Sulphides and native gold distribution within the veins are patchy. The veins average approximately one meter in thickness and range from half a meter to four meters in length. Related wall-rock alteration includes haloes of moderate to pervasive sericite ± chlorite and carbonate replacing feldspar within the host intrusive.

Final Results


Operadora Minera has successfully completed 12,240m of its planned 15,000m of 2020 drilling program. The results presented here correspond to 38 drill holes completed to date in the north extension of the Cordero-Balvina target, located in the El Bagre Mining Project. The drill holes were carried out approximately perpendicular to the vein direction as to have down-hole lengths as close as possible to vein widths. The drilling results have extended the Cordero-Balvina vein extension to the north by 500m and down dip by 200m. Ten drill holes intercepted high-grade gold over thick continuous intervals, and sixteen drill holes intersected low-grade gold.

Note: Lengths are drill intersections and not necessarily true widths. Although true widths were not consistently calculated yet for comparison purposes between holes, the down-hole lengths presented here, it is expected to correspond to them. Negative drill-holes are not shown. Pending ALS lab report for the drill holes BCNDDH_20_34 to BCNDDH_20_38. These drill holes were analyzed in La Ye internal laboratory.


Sixteen of the twenty-six drill holes in the 2020 program encountered low-grade gold due to NNW trending faults, limiting the north extension of the Cordero-Balvina vein. Kinematic indicators on the fault planes suggest a left-lateral displacement of the vein to the NNW. This hypothesis is supported by the presence of small miners in this area. (see map #2).

Next Exploration Step


According to the exploration strategy of the Company, the drill rig is now moving to explore the continuity down-dip of Cordero-Balvina. This in-fill drilling plan of 2,700m will be focused on upgrading the inferred resources into indicated resources (see RPA NI 43-101 Technical Report) and confirm the continuity of the vein down-dip (see cross-section #1). Additionally, the exploration drilling of the Renacer underground mine is planned. This drilling plan of 3,000m will be focused on demonstrating and confirming the continuity of the Limon vein to the South at the hanging-wall of the El Limon fault zone (see cross-section #2). This drilling will begin in October when the second drill rig arrives at the project. The Company’s geological team has now completed the integration of historical data from the El Limon mine into a 3D geological model built in Leapfrog Geo®. This geological model is a significant achievement that helps understand the ore-controlling structures and reduces mineral exploration risks.


All permits, logistics and access related to both exploration programs are in place. Both drilling plans are expected to complete by the end of December 2020.

QA/QC Controls


For exploration core drilling, the Company applied its standard protocols for sampling and assay. NQ core was sawn or split with one half shipped to a sample preparation laboratory in Medellin run by ALS Colombia Limited. Samples were then shipped for analysis to an ALS-certified assay laboratory in Toronto, Canada. The samples were analyzed for gold using standard fire-assay on a 50-gram sample with an AA finish. Multi-element geochemistry was determined by ICP-MS using either aqua regia (ME-MS41) or four acid (ME-MS61) digestions. Blanks, duplicates and certified reference standards were inserted into the sample stream to monitor laboratory performance. A comparison of control samples and their standard deviations indicated acceptable accuracy of the assays and no detectible contamination. Due to COVID-19 contentions, one half of the samples was analyzed in La Ye’s internal laboratory. The remainder of the core is stored in a secured storage facility for future assay verification.

Mr. Paulo J. Andrade, P. Geo., BSc. Senior Geologist, VP Exploration for Soma Gold Corp. is the Qualified Person, within the meaning of NI 43-101. Mr. Andrade is satisfied that the analytical procedures and best practices used are standard industry methodologies, and he has reviewed and approved the technical information disclosed in this news release.




Soma Gold Corp. is a mining company focused on gold production and exploration. The Company owns two adjacent mining properties in Antioquia, Colombia with a combined milling capacity of 675 tpd. (permitted for 1,400 tpd.). The La Ye mine is currently operating and producing, and the El Limon mine and mill are scheduled to begin operating in Q1 2021. Internally generated funds will be used to finance a regional exploration program.


The Company also owns an exploration and development property near Tucuma, Para State, Brazil.
