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)

VANCOUVER, B.C. - Turmalina Metals Corp. (“Turmalina”, or the “Company”; TBX-TSXV, TBXXF-OTCQX)

is pleased to announce that the first three holes of our Phase Two (~5000 meter) drilling program at the

San Francisco project (“San Francisco” or the “Project”) have intersected broad intervals of high-grade

gold-silver-copper mineralisation at the San Francisco de Los Andes (“SFdLA”) 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)

o 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)

o Including 27m @ 9.02 g/t Au, 94 g/t Ag & 1.08% Cu (11.4 g/t AuEq) from 31m

o Including 3m @ 13.8 g/t Au, 111 g/t Ag & 0.08% Cu (15.3 g/t AuEq) from 15m

o Including 6.7m @ 7.43 g/t Au, 58 g/t Ag & 0.15% Cu (8.35 g/t AuEq) from 65m

o 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)

o 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.

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.

Statements

About Turmalina Metals and the San Francisco Project: Turmalina Metals is a TSXV-listed exploration company

focused on developing our portfolio of high grade gold-copper-silver projects in South America. Our focus is on

tourmaline breccias, a deposit style overlooked by many explorers. Turmalina Metals is led by a team responsible

for multiple gold-copper-silver discoveries who are highly experienced in this deposit style. Our projects are

characterised by open high-grade mineralisation on established mining licenses that present compelling drill

targets. The principle project held by Turmalina is the San Francisco project in San Juan, Argentina. For further

information on the San Francisco Project, refer to the technical report entitled “NI43- 101 Technical Report San

Francisco Copper Gold Project, San Juan Province, Argentina” dated November 17, 2019 under the Corporation’s

profile at www.sedar.com.

Sampling and Analytic procedure: Turmalina Metals follows systematic sampling and analytical protocols which

exceed industry standards and are summarized below.

All drill holes are HQ diameter diamond core holes. Drill core is collected at the drill site and transported by

vehicle to the Turmalina core logging facility in Villa Nueva, where recovery and RQD (Rock Quality Designation)

measurements are taken before the core is photographed and geologically logged. The core is then cut in half with

a diamond saw blade with half the sample retained in the core box for future reference and the o ther half placed

into a pre-labelled plastic bag, sealed with a plastic zip tie, and identified with a unique sample number. The core

is typically sampled over a 1 to 2 meter sample interval unless the geologist determines the presence of an

important geological contact. The bagged samples are then stored in a secure area pending shipment to the ALS

sample preparation facility in Mendoza where they are dried, crushed and pulverized. Following sample

preparation the prepared pulps are then sent to the ALS laboratory in Lima for assay. The samples are then

analyzed using a 50g aqua regia digest and fire assay-AA finish analysis for gold and four acid digestion with ICP-MS

analysis for 53 other elements. Samples with results that exceed maximum detection values for gold are re -

analyzed by fire assay with a gravimetric finish and other elements of interest are re -analyzed using precise ore-

grade ICP analytical techniques. Turmalina Metals independently inserts certified control standards, coarse field

blanks, and duplicates into the sample stream to monitor data quality. These standards are inserted “blindly” to

the laboratory in the sample sequence prior to departure from the Turmalina Metals core storage facilities.
