Phase Two Drilling Intersects Further High-Grade Gold-Silver-Copper Mineralisation Including 109m at 4.9 g/t Au, 109 g/t Ag and 1.1% Cu (7.5 g/t AuEq)

 

 

 

 

 

Turmalina Metals Corp. (TSX-V:TBX) (OTCQX:TBXXF) is pleased to announce that the first three holes of our Phase Two (~5000 meter) drilling program at the San Francisco project have intersected broad intervals of high-grade gold-silver-copper mineralisation at the San Francisco de Los Andes breccia. Significant intersections are reported in Table 1 below, and include:

 

  • 83m @ 4.4 g/t Au, 82 g/t Ag & 0.43% Cu (5.9 g/t AuEq) from 25m (SFDH-011)
    • Including 41m @ 7.03 g/t Au, 91 g/t Ag & 0.51% Cu (8.76 g/t AuEq) from 27m
  • 109m @ 4.94 g/t Au, 109 g/t Ag & 1.1% Cu (7.55 g/t AuEq) from 12m (SFDH-012)
    • Including 27m @ 9.02 g/t Au, 94 g/t Ag & 1.08% Cu (11.4 g/t AuEq) from 31m
    • Including 3m @ 13.8 g/t Au, 111 g/t Ag & 0.08% Cu (15.3 g/t AuEq) from 15m
    • Including 6.7m @ 7.43 g/t Au, 58 g/t Ag & 0.15% Cu (8.35 g/t AuEq) from 65m
    • Including 11m @ 5.59 g/t Au, 134 g/t Ag & 1.34% Cu (8.75 g/t AuEq) from 98m
  • 74m @ 1.1 g/t Au, 48 g/t Ag & 0.41% Cu (2.2 g/t AuEq) from 88m (SFDH-013)
    • And 13m @ 0.9 g/t Au, 51 g/t Ag & 0.54% Cu (2.1 g/t AuEq) from 179m

 

These high-grade intersections remain open both at depth and laterally. The breccia textures observed in the drill core confirm that the current intercepts are related to the very top of the breccia system. Mineralisation in the top of tourmaline breccias may have a different orientation to the orientation of the breccia pipe (such as forming flat-lying ‘ceiling’ zones): Should the above drill intersections be at an oblique angle to mineralisation then the true width of mineralisation will be less than the reported intersections. Further drilling and geological modelling is required to constrain the geometry of mineralisation within the SFdLA breccia.

 

The current Phase Two drilling program tests for extensions to high-grade gold-copper-silver mineralisation encountered in the first phase of drilling completed by the Company in 2019, which included intersections of 36.9m @ 6.3 g/t Au, 122 g/t Ag & 0.88% Cu (8.7 g/t AuEq, SFDH-001) and 85.3m @ 4.4 g/t Au, 109 g/t Ag & 0.79% Cu (6.6 g/t AuEq, SFDH-002; see Turmalina news release dated December 2, 2019 for full details).   

 

Dr. Rohan Wolfe, Chief Executive Officer, states:

 

“These outstanding initial results from our Phase 2 drilling indicate that high-grade mineralisation not only continues at depth at SFDLA but, as expected by our geological model, the SFdLA breccia pipe is starting to expand in width as we go deeper. Our 2019 campaign tested the SFdLA breccia pipe to a depth of 150 meters. These initial Phase 2 holes test the breccia pipe 30 to 150m below the 2019 drill holes and have returned similar high grades. Most tourmaline breccias are considered to be gold-rich at 1 g/t gold – so the broad intersections of gold-mineralised breccia returning 9-10 g/t gold at San Francisco are quite remarkable.

 

“With high-grade mineralisation open at depth and laterally these are exciting times for Turmalina Metals and we look forward to keeping the market informed of new drilling results both at SFdLA and at satellite breccias that will be tested by the current program.

 

“We have also been actively consolidating our holdings in the region with the recent acquisition of the neighboring Miranda properties. While our focus remains very much on San Francisco we have also strengthened our overall portfolio by acquiring the Chanape project in Peru, which contains a cluster of strongly gold-copper mineralised tourmaline breccias. We look forward to providing more detailed information on our acquisitions as we complete field work on these projects.”

 

Drilling continues at the San Francisco Project, with 14 holes completed to date for a total of 3890m. Ten of these holes tested the SFdLA breccia pipe while four holes tested two breccia targets identified during the summer field program. The assays for the first three Phase 2 holes have been returned and are reported in this release, samples from a further three holes have been dispatched for assay at a commercial laboratory, and drill core from the remaining holes are currently being logged and sampled prior to dispatch for assay. The current drilling aims to extend mineralisation at SFdLA to greater depths as well as test for lateral extensions. In addition, the current program tests four of over sixty gold-copper mineralised breccias identified during the summer field program.

New Acquisitions

 

The Company continues to consolidate our holdings in the mining friendly state of San Juan, as well as review opportunities in South America.

 

Miranda Properties, San Juan, Argentina.

 

As part of our regional consolidation around the San Francisco project the company is pleased to announce that it has, under its Argentinian subsidiary Aurora Mining S.A, entered into an option agreement with third parties to acquire a 100% interest in the 17,690 ha Miranda properties, located ~4 km to the east and northeast of our Project area. The Company can acquire a 100% interest in the Miranda properties by making total cash payments of USD$225,000 over four years, with $150,000 of the payment due in the final year. The vendors retain a NSR of 1%, which can be purchased for USD$300,000.

 

The Miranda properties covers a large area prospective for gold and base metal mineralisation on the eastern margin of the San Francisco Project.  

 

Chanape Project, Lima, Peru.

 

As part of the Company’s strategy to possess several high-grade projects in our portfolio the Company is pleased to announce that it has, under its Peruvian subsidiary Aurora Copper Peru S.A.C, entered into an option agreement with third parties to acquire a 100% interest in the Chanape Project, located in Lima district, Peru. The Company can acquire a 100% interest in the 680 ha property by making total cash payments of $3,410,000 and by incurring exploration expenditures of US$2,000,000 over 5 years, with $2.2M of the cash payment and $750k of the exploration commitment due in the final year. The vendors retain a 2% Net Smelter Returns royalty, of which the Company may purchase 1% (50%) of the NSR for a payment of USD$ 1,200,000.

 

The Chanape Project hosts over 50 tourmaline breccias, however previous exploration focused on testing porphyry copper-molybdenum mineralisation on the property (i.e. 284m @ 0.32% copper, 82 ppm molybdenum and 6 g/t silver). The last two holes drilled by the previous operators tested two tourmaline breccias and returned the best intersections drilled to date at the project (i.e.  71m @ 1.92% copper, 0.84 g/t gold & 42 g/t silver and 108m @ 2.0 g/t gold & 41 g/t silver). These breccias remain largely untested and are open at depth and along strike. Turmalina Metals plans to review and prioritise tourmaline breccia mineralisation on the project.

 

About the San Francisco Project

 

The 3404 ha San Francisco project is located in San Juan, Argentina. The project area contains over 60 tourmaline breccia occurrences, several of which have supported small-scale mining. The Company is focused on mapping and sampling the breccias in the project area, and drill testing the highest priority targets.

 

To minimize the risk of COVID-19 transmission to our team and the community the Company has applied rigorous protocols throughout the program. These protocols have been approved by the authorities of the province of San Juan, and both Turmalina Metals and Aurora Mining maintain close contact with the local authorities in order to comply with all regulations. These procedures include social distancing, improved hygiene, health screening of all staff and contractors, longer rosters at our remote field camp and an onsite medical professional to monitor health and ensure procedures are followed.
