TORONTO, Feb. 13, 2023 (GLOBE NEWSWIRE) -- Fredonia Mining Inc. (“Fredonia” or the “Company”) (TSXV:FRED) announces successful completion of its phase III drilling program, with results of the remaining 6 HQ diamond drill holes totaling 1,143.00 m. drilled at the Northern Monserrat sector of its EDM project. The phase III drill program included an aggregate of 12 holes for a total of 2,955 m – 6 holes in the southern Herradura Hill target (see Fredonia news release dated January 31st, 2023) and the last 6 holes at the Northern Monserrat sector (drilled at the Main Veins, Bajo Pedernal and Monserrat West targets).

“We are very encouraged to learn that the Bajo Pedernal target, which joins the Monserrat West target to the Main Veins target, has multiple veins under modern rock cover, with potential to host high-grade ore shoots, similar to those already detected at the Main Veins and Monserrat West targets,” said Estanislao Auriemma, Chief Executive Officer of Fredonia. “Also very pleased to learn that the strike of the veins continues to the north under the post-mineral basalt flow, which indicates a significant increase in the mineralized area at the EDM project. The high-grades of gold and silver drilled in the Northern Monserrat sector, and those drilled at the Herradura Hill target in this current exploration program, confirm the growing potential of the EDM project.”

This phase III drill program was design to cover two targets within the Northern Monserrat sector:

• A four-hole fence completes a full 1.1 km long cross-section to encompass a large unexposed Bajo Pedernal target covered by modern rocks. This cross-section spans the area between the Main Veins and Monserrat West targets.
  
  
• The drill-hole fence intercepted multiple zones of stockworks, veins and breccias containing high- grade of gold and silver, with 0.60m @ 6.18 g/t Au Eq. at BPDDH001. The new intercepts added to the historical intercepts at Main Veins and Monserrat West, in the Northern Monserrat sector. (see Figure 3).
  

The two additional drill holes at the Main Veins target extend its strike and open the system to the north, under the basalt flow, intersecting a wide ore shoot with high-grade - 4.00m @ 1.66 g/t Au Eq. and 4.00m @ 1.49 g/t Au Eq at MVDDH078. (see Figure 4).

Figure 1: Map showing the location of the main targets at the Northern Monserrat sector - El Dorado Monserrat gold-silver project (6,200 ha licenses).

The Northern Monserrat sector comprises an area 3.5 km long by 3.2 km wide, made up of mineralized corridors hosted in andesitic lavas that form country rock, and contains more than 20 kilometers of epithermal veins, not all of which have been explored or drilled. There is evidence of buried veins unexplored or as extensions to understand the vein systems. All prospects discovered up to date have not been limited along strike or dip.

Two different strikes of faults host the mineralization: north-south "horst and graben" faults, and NW-SW shear faults. The crossings, nodes, and inflexion between both structures control the location of the high-grade gold and silver ore shoots, and reveal the potential at the Northern Monserrat sector.

(*) Reported interval lengths are down-hole widths and not true widths.
(**) Gold equivalent (“Au Eq.”) is calculated using metal prices of US$ 1,800/oz for Au and US$ 24/oz for Ag. The equation used is: Au Eq g/t = Au g/t + (Ag g/t ÷ 75).
Au Eq assumes Au recovery of 90%. The limited metallurgical studies by Fredonia (selective Bottle rolls from Main Veins material) have indicated high (>90%) recovery of gold in oxide material. The Cerro Vanguardia mine to the east of EDM with similar mineralization reports recoveries in the high 90% for Au.

Main Veins Target

To the east, the current drill-hole fence integrated with Main Veins target has received most of the historical exploration focus and remains as an advanced target of merit. Main Veins extends for over 2.0 km long and a 25 m wide. The mineralization show multiple ore shoots open at depth, with subvertical plunge that has been tested down to -200 m below the surface, and remains open significantly to the north and at depth. To the south the Main Veins target merges with the Abanico target veins field.

The Main Vein target has received the most drilling thus far, including:

Monserrat West Target

To the west, the drill-hole fence integrating with Monserrat West target is located on a north-south dilatational, 1.6km long corridor that contains ore shoots expressed as veining and brecciation, that open in both directions. The sparce surface expression is characterized by a silica cap, secondary oxidation, leaching, breccia and residual quartz textures. The historical drill holes intersected the target structure and contain high-grade significant gold and silver intervals demonstrating the potential for further strike and down dip extension, but also the possibility of further high-grade gold and silver ore shoot zones.

(**) Gold equivalent (“Au Eq.”) is calculated using metal prices of US$ 1,800/oz for Au and US$ 24/oz for Ag. The equation used is: Au Eq g/t = Au g/t + (Ag g/t ÷ 75).
Au Eq assumes Au recovery of 90%. The limited metallurgical studies by Fredonia (selective Bottle rolls from Main Veins material) have indicated high (>90%) recovery of gold in oxide material. The Cerro Vanguardia mine to the east of EDM with similar mineralization reports recoveries in the high 90% for Au.

Phase III drilling has confirmed the location of multiple ore shoots in the Northern Monserrat sector, with extensive intersections of gold and silver mineralized veins, extending the known mineralization to the north at the Main Veins target, under the basalt flow. It also extended the Bajo Pedernal target, which has very little surface expression (jasperoidal veins) but which now show similar potential as the more advanced Main Veins and Monserrat West targets.

In addition, there are numerous targets that are yet to be drilled such as Abanico, that comprise at least four distinct veins traceable over 1.0 km of strike; and Monserrat East, a silicified trend reaching 3.0km long by 8m wide located 2.5km east of Main Veins.

Based on all of the above, the Northern Monserrat sector requires additional systematic drilling to define the true extent of the sector, currently open in all directions.

The interpretation of this new phase of drilling is currently being carried out, including integrating it with the historical drilling. This will provide the basis for future exploration drilling and selection of other potential high-grade zones.

Quality Assurance/Quality Control:

All core samples were submitted to the principal Alex Stewart Laboratories in San Julián city for preparation and in Mendoza city for the analysis. All samples were analyzed for Au and Ag by fire assay/ AA finish 50 g, plus a 39-element ICP-AR finish. Fredonia followed industry standard procedures for the work with a quality assurance/quality control (QA/QC) program. Blanks and reference material of High grade/ Low grade Gold and High grade/ Low grade Silver standards were included with all sample shipments to the principal laboratory. Field duplicates were made from Coarse Reject. Fredonia detected no significant QA/QC issues during review of the data.
