Platinex reports high grade gold results at Ronda claims, Shining Tree Property, including 9.04 g/t Au over 16.15 m at surface

TORONTO, Feb. 07, 2024 - Platinex Inc. (CSE: PTX) (OTCQB: PANXF, Frankfurt: 9PX) ("Platinex" or the "Company") is pleased to announce results from its mechanized stripping and channel sampling program at the Ronda claims located in the central area of the district scale Shining Tree Gold Property, Ontario. The Shining Tree Property is held through the South Timmins Mining Joint Venture ("South Timmins JV") with Fancamp Exploration Ltd..

The program is the first significant work program since Platinex acquired the Ronda surface claims from Alamos Gold in 2022 and has confirmed the high-grade nature of the Ribble structure at surface. The surface claims are directly above the historical underground workings owned by Platinex. The Ronda mine was a small-scale historical producer with two shafts and underground workings and produced 2,727 oz. gold and 4,830 oz. silver from 22,309 tonnes of ore during its one-year mine life (1939-1940).¹

The program reported significant gold grades over broad widths with highlights from composite channel samples including:

• Channel N30 assayed 9.04 g/t Au over 16.15 m, including 60.30 g/t Au over 1.00 m
• Channel N33 assayed 4.54 g/t Au over 13 m, including 8.88 g/t Au over 1.05 m
• Channel N36 assayed 5.63 g/t Au over 7.95 m, including 11.50 g/t Au over 0.90 m
• Channel N31 assayed 7.97 g/t Au over 4.95 m, including 14.50 g/t Au over 0.65 m
• Channel N38 assayed 4.49 g/t Au over 8.05 m, including 11.30 g/t Au over 1.95 m
  

"Exploration at Shining Tree/Ronda was previously constrained by not having the surface rights. The mineralization appears to be continuous across much of the exposed face of the vein and immediate wall rock, and the returned gold and silver grades are consistent with historical grades reported from the Ronda Mine, thereby strengthening confidence that significant additional gold and silver mineralization exists on the Ronda claims," says Greg Ferron, President, and CEO of Platinex Inc.

Individual samples highlights include:

• Sample 504509 assayed 60.30 g/t Au over 1.00 m
• Sample 504508 assayed 25.70 g/t Au over 1.05 m
• Sample 504657 assayed 15.50 g/t Au over 0.70 m
• Sample 504594 assayed 11.30 g/t Au over 1.95 m

Mineralized widths were reported with a 0.3 g/t Au cutoff, and a maximum allowable interval of 3 meters below a 0.3 g/t Au cutoff grade within a reported channel sample interval. Intervals are reported as composites of the sampled lengths and are not true widths. Individual samples within the composite channel sample intervals averaged 0.87 meters.

The Ribble vein and immediately surrounding wall rock is structurally more complex than previously described or understood in the historical literature.

See the Company's website for a complete table of composites, channel sample results and additional maps.

Gold grades at Ronda, are associated with generally steeply dipping, variably folded, east-northeasterly trending quartz veins, which are oriented highly oblique to the northerly trending, 65 degrees west dipping structural zone (Ribble Zone) that hosts the veins. Channel sampling was conducted perpendicular to those veins and is therefore roughly parallel to the host structure. At Ronda, historical mining was conducted to about 205 m depth across widths of 2 to 3 meters, which includes an uncertain amount of hanging and footwall dilution. The average dip of the mined Ribble structure was 65 degrees to the west. This is consistent with mapping of the veining at surface, occurring within a zone having an apparent width of 3 to 4 meters in the North trench, and a much narrower and more sporadic zone of veining in the south trench.

Future work will investigate the potential across strike, in the hanging and footwall, for additional mineralized structures. Limited historic drilling may have not adequately tested that potential, as holes were drilled perpendicular to the Ribble structure and therefore roughly parallel to the mineralized veins.

Ronda North Trench Overview:

• A total of 1,912 m² were mechanically stripped, washed, and channel sampled.
• A total of 150 individual channel samples were cut with lengths that ranged from 0.30 m to 1.70 m and averaged 0.94 m.
• 81 channel samples exceeded 1 g/t Au, including 33 channel samples over 5.00 g/t Au and 14 channel samples exceeding 10 g/t Au.
• Results ranged from 0.01 g/t to 60.30 g/t Au, and <0.30 g/t to 51.40 g/t Ag with a high sample value of 60.30 g/t Au.

Ronda South Trench Overview:

• A total of 448 m² were mechanically stripped, washed, and channel sampled.
• A total of 78 channel samples were collected with lengths that ranged from 0.10 m to 1.20 m and averaged 0.74 m
• 20 channel samples exceeded 1 g/t Au, including 12 channel samples over 5.00 g/t Au and 6 exceeding 10 g/t
• Results ranged from 0.01 g/t to 20.90 g/t Au, and <0.30 g/t to 83.60 g/t Ag with a high sample value of 20.90 g/t Au.

Geology overview:

The stripping program exposed a broad northeast-trending shear zone (or two parallel shear zones as there is a 90 m zone of overburden in between the two north-trending stripped areas) with a width of up to approximately 200 m in total. The shear zone is part of a suite of secondary conjugate faults that are related to the east-trending Ridout-Tyrrell Deformation Zone.

The shear zone within the stripped areas is strongly schistose with variable amounts of pervasive iron-enriched hydrothermal alteration along with sets of s-folded quartz veins that reflect episodes of brittle-ductile fracturing and quartz infilling to or oblique to the schistosity during progressive left-handed shearing. The north-trending, west-to-southwest dipping Ribble vein is exposed on moderately to steeply west-facing slopes in both stripped areas (as a sheet-like body). At the Ronda North stripped area, the eastern half of the exposed outcrop has been eroded below the level of the projected "up-plunge" extension of the vein system. The exposed Ribble vein has been interpreted as tightly buckle-folded discontinuous portions of a once continuous quartz vein with the fold hinges and limbs moderately plunging to the south-southwest.

Channel samples were typically orientated perpendicular to the schistosity and the limbs of folded quartz veins along the dip-slope of the vein system.

QA/QC Program

Channel samples were cut using a diamond blade saw, inserted into labelled bags, and delivered by representatives of Platinex to Activation Laboratories Ltd. in North Bay, Ontario. Activation Laboratories Ltd. is an ISO 17025:2005 accredited testing laboratory.

Samples were analyzed by fire assay using the 1A2 package with a gravimetric finish (1A3 package) for samples that returned greater than 5,000 ppb Au. Multi-element analysis was completed by near-total digestion (four-acid) with an ICP-OES finish (IF2 package). Platinex inserts standards and blanks and performs duplicate analysis as part of its QA/QC program. Activation Laboratories also performs an internal QA/QC program which includes the insertion of CRM's, blanks, sample repeats, and duplicate samples.

Corporate

In addition, in January, the Company completed a share for debt issuance totaling $58,000 by issuing 1,160,000 common shares at a price of 5 cents per share to four arm's length parties. The shares are subject to a statutory 4-month hold period.
