Portofino Resources; gold in Ontario, Canada + lithium brines in Argentina

It has been a busy six weeks for Portofino Resources (TSX-V: POR), six press releases have been issued. I will reiterate the key takeaways, but first an update on Portofino’s South of Otter (“SOT“) property in the Red Lake mining district. Although SOT is a priority, all four properties in northwestern Ontario will likely see exploration this year. 

South of Otter, ~9 km from Great Bear’s Dixie project

The 5,207-hectare SOT project is 40 km southeast of Red Lake, Ontario and about nine km east of Great Bear Resources’ (“GBR“) very high-grade Dixie project. In the past, SOT was the subject of large-scale geophysical surveys designed to target base metals. However, in 2001 Goldcorp completed a property-wide compilation & interpretation of prior ground & airborne magnetic data to assess the potential for gold. Due to a lack of outcrop rocks, minimal follow-up work was done.


Management just completed a field program of prospecting & geological mapping along strong conductors identified in the Company’s winter electromagnetic (“EM”) ground survey. A total of 32 samples were collected to test various styles of mineralization, lithologies & alteration.

The work program included prospecting, detailed structural mapping & outcrop channel sampling based on conductors found in the geophysical survey announced on May 14th. A lack of detailed historical work enables Portofino to undertake meaningful programs, guided in part by successes of neighboring exploration companies.

In addition to the collection of 32 samples, significant semi-massive to massive sulphide mineralization was discovered along a newly identified, 1.6-km long fault zone. This zone is located ~500 m south of previously identified gold soil sample anomalies & EM conductors. A total of 12 samples were collected along this (deformation) zone to test for the presence of Au, Ag, Cu & Zn.

Notice in the image below drill holes (“DH“) / historical resources including; DH: 1.5% Cu + 6.3% Zn (3.7% Cu Eq.) over 3.4 m; 110,000 tonnes @ 0.5% Cu + 12.5% Zn (4.9% Cu Eq.); DH: 1.4% Cu + 7.3% Zn (4.0% Cu Eq.) over 9.5 m; 100,000 tonnes @ 1.0% Cu + 10% Zn (4.5% Cu Eq.).


Further prospecting & geological mapping on the margins of this fault zone identified alteration in the volcanic wall rock. Many gold deposits in Ontario are either directly hosted in this mineralization or exist in close relationship to it and a fault zone. Other projects containing this type of mineralization along similar deformation zones include GBR’s Dixie and the Uchi Lake gold mine. Once additional permits are received, Portofino will proceed to trenching / drilling.

Three new gold properties secured in past month

These are exciting times for Portofino. Management had an opportunity to pick up additional low-cost properties with gold showings, so they did. All three properties are located in historical & current mining districts with ample infrastructure & easy access. In addition to Red Lake, management expects the Atikokan area to heat up this summer. A number of companies are increasing their exploration activities there.

Portofino began negotiating & planning to lock up gold properties in Ontario when gold was around US$1,400/oz. Today, [June 24th], August gold futures are at US$1,786/oz., a gain of ~28%. Therefore, without a single new drill hole on any of its four controlled properties, the value the Company’s assets has meaningfully increased.


On June 11th, Portofino announced the execution of a binding agreement to acquire six claims (869 hectares) in the Atikokan area of northwestern Ontario. The Melema West property is located 28 km northeast of the town of Atikokan, and 5 km north of the Quetico Fault. Agnico Eagle Mines’s Hammond Reef gold deposit is ~19 km northwest of Melma West. Hammond Reef hosts a large, near-surface Measured & Indicated resource of 4.5 million ounces gold.

Grab samples taken in 2019 assayed as high as 10 g/t gold. The Young-Corrigan vein-system ranges in width from 1 to 15 m and was mapped over a strike of at least 170 m. Positive gold values demonstrate that an additional undocumented gold-bearing structure potentially exists on the Melema West property.

CEO David Tafel of Portofino commented on the Melema West property, 

“The gold-bearing structures in this area are extensive, well documented and traceable for > 30 km. Recent land acquisitions by Agnico Eagle contiguous to Melema West supports the idea that Portofino is well strategically placed. The undocumented & unexplored Young-Corrigan Shear Zone is a compelling exploration target.”

On May 27th, Portofino executed a binding agreement to acquire three claims totaling 1,147 hectares in the northwestern Ontario. The Sapawe West property is nine km northeast of Atikokan, just north of the Quetico Fault, and 2.5 km west along strike of the past producing Sapawe Gold mine. Portofino has initiated the compilation & reinterpretation of all available historic data on the property and is proceeding to develop exploration targets for a summer field program.

Hammond Reef, located ~13 km north of the Sapawe West property, is in a structurally active portion of the Steep Rock Greenstone Belt. Similar to the structure associated with Hammond Reef, Sapawe West hosts a possible northeast trending splay from the Quetico Fault.


CEO Tafel commented on the Sapawe West property,

“We are excited to acquire this strategically located property. The nearby past-producing Sapawe Gold mine, the visual results from Falcon Gold’s drill program along the same geological corridor, and the lack of drilling on the Property, makes for a compelling exploration target. We look forward to commencing initial field work.”

This news came just a week after executing a binding option agreement for the right to acquire a 100% interest in the Gold Creek property, also in northwestern Ontario. The block comprises three mining claims, is easily accessible by road, and covers ~1,010 hectares.

Historical activity at Gold Creek included:

From 1967 to 1973, prospecting, mechanical stripping / trenching & rock sampling of quartz vein occurrences in the district. In 1983, geological mapping, magnetic & VLF-EM surveys further assessed the area.

In 1985 & 1987 to 1989, Noranda Exploration conducted extensive work, they explored the area with an airborne magnetic & electromagnetic survey, ground magnetic & electromagnetic surveys, selective radiometric & gravity surveys, geochemical sampling, geological mapping / overburden stripping, & rock sampling.


Inco Gold conducted an exploration program in 1989-90 which consisted of grid line cutting, magnetic, VLF-EM & geological mapping surveys, trenching, rock sampling & two diamond drill holes. Two grab samples assayed 13.2 g/t & 64.2 g/t gold.

Significant gold mineralization has been traced along a 1.5-km strike length with grab samples returning values up to [759 g/t = 24.4 ounces / tonne] (from an OGS property visit) and diamond drill intersections in 2008 of up to 2.3 g/t over 8.3 m.

CEO Tafel commented on the Gold Creek property,

“This transaction allows us to continue to build our gold portfolio within the easily accessible, active & historic gold mining area of northwestern Ontario. Multiple visible gold occurrences reported by previous operators is very encouraging, and gives our technical crew a head start in planning initial exploration activities.” 

Gold Creek is characterized by geology similar to that documented in the Kirkland Lake area, where numerous gold showings occur in a broad range of lithologies. Visible gold sometimes occurs within the mineralized veins. Management has initiated the compilation & re-interpretation of all available historic geochemical & geophysical data at Gold Creek to develop exploration targets for summer field work.


Portofino Resources (TSX-V: POR) is up 225% from its 3-yr. low, but its market cap is only C$3.2M. In addition to the four properties described above, the Company has lithium brine assets in Argentina that could be worth C$ millions once energy metals regain popularity. If management could farm out one or more gold / lithium properties, it could reduce already low cash burn to virtually zero. Shareholders would have a free option on the remaining controlled properties.

In looking at peer Red Lake properties (and companies with nearby Atikokan area properties), the average gain from 3-yr. lows is 1,640%. Even excluding GBR’s staggering performance, the average gain is 2.5 times that of Portofino. Perhaps not Great Bear, but others on the above chart could be interested in acquiring companies like Portofino to gain additional regional gold exposure.
