Marathon Gold Delineates Additional In-Fill Gold Mineralization at Berry Deposit, Valentine Gold Project

Results include 1.96 g/t Au over 26m, 5.96 g/t Au over 8m, 1.88 g/t Au over 20m

TORONTO, Feb. 02, 2023 (GLOBE NEWSWIRE) -- Marathon Gold Corporation (“Marathon” or the “Company”; TSX: MOZ) is pleased to provide assay results on the final twenty-six in-fill drill holes completed during 2022 at the Berry Deposit, part of the Valentine Gold Project located in central Newfoundland (the “Project”).

During 2022, Marathon completed 21,039 metres of diamond drilling at Berry targeting areas that are assumed in the Berry geological model to be composed primarily of un-mineralized waste but are within the conceptual pit shells used in the MRE. Success with this program has the potential to add mineable ounces to the Project’s mine plan. Assays from 15,301 metres of the 2022 drilling were previously reported (news releases dated June 15, September 12, 2022, and January 12, 2023). These latest results represent fire assay data from the final 5,738 metres of drilling and include results from two previously drilled holes that were re-opened and extended as part of the 2022 program. Highlights include:

  • VL-20-882 EXT intersected 1.96 g/t Au over 26 metres including 25.79 g/t Au over 1 metre, and 5.96 g/t Au over 8 metres including 22.89 g/t Au over 2 metres, and 1.59 g/t Au over 13 metres including 10.93 g/t Au over 1 metre;

  • VL-22-1274 intersected 1.88 g/t Au over 20 metres including 14.23 g/t Au over 1 metre, and 0.96 g/t Au over 36 metres, and 1.29 g/t Au over 16 metres including 12.77 g/t Au over 1 metre; and

  • VL-22-1262 intersected 30.03 g/t Au over 1 metre and 13.36 g/t Au over 1 metre.

All quoted intersections comprise uncut gold assays in core lengths. All significant assay intervals are reported in Table 1.

Figure 1: The Berry Deposit (View South), with drill holes completed during 2022 after the cut-off for the 2022 MRE. “Significant” intercepts (averaging >0.70 g/t Au) are shown in red (previously disclosed) or purple (today’s release). All visible intercepts occur outside the Quartz-Tourmaline-Pyrite-Vein mineralized domain (shown in yellow) and are predominantly outside the 2022 MRE.

Matt Manson, President and CEO, commented: “With this final batch of 2022 Berry drill results, we continue to see intercepts of high-grade mineralization outside of Berry’s currently modeled mineralized domains. As a reminder, this in-fill program was designed to target areas of the deposit assessed to comprise primarily un-mineralized waste rock. As with our previous batch of results, we are delineating a sizeable domain of quartz-tourmaline-pyrite veining at the base of the mineral resource pit shell. In this case, it is at the northeastern limit of the deposit and represents the deeper extension of one of three northeast plunging ore shoots. This area was targeted with an extension of the 2020 diamond drill hole VL-20-882, and is illustrated in long-section in Figure 4 and cross-section in Figures 5 and 6. The 2022 in-fill drilling at Berry has been very successful in delivering new areas of mineralization, and supports our assessment that additional mineable ounces remain to be delineated within the scope of the Project’s current mine plan.”

Gold Mineralization at the Valentine Gold Project

Gold mineralization at the Valentine Gold Project is contained in Quartz-Tourmaline-Pyrite-Gold (“QTP-Au”) veins developed within granitoid rocks of the Valentine Lake Intrusive Suite (“VLIS”) on the hanging wall, or northwest, side of the Valentine Lake Shear Zone (“VLSZ”; Figure 2). Up to four orientations of veins have been measured, with shallowly southwest dipping “Set 1” QTP-Au veins observed to be dominant in both abundance and gold content. At the Leprechaun, Marathon and Berry Deposits, Set 1 QTP-Au veins form densely stacked corridors of mineralization referred to as “Main Zones”. The extent and scale of these mineralised corridors appear related to the size and frequency of sheared mafic dykes which extend northeast-southwest within the granitoid rocks, parallel to the shear zone.

Berry Deposit Drill Results

The drill results released today are derived from twenty-six drill holes located between sections 13570E and 14910E. The drill holes were located along the full 1.5 kilometre extent of the Berry Deposit, and located in areas of the Berry geological model that had been previously underexplored with a view to identifying new areas of mineralisation or validating areas of mineralisation previously modelled with lower confidence. Six holes were located in the western hanging-wall area of the deposit, eight were located in the central hanging-wall area, nine were located in the eastern hanging-wall area, and three were located in the footwall area close to the Valentine Lake Shear Zone (Figure 3). Twenty-five holes were oriented steeply to the northwest testing for Main Zone-type stacked QTP-Au mineralization in “Set 1” vein orientations. One hole was oriented more shallowly towards the SE. VL-20-882-EXT and VL-22-1202-EXT represent extensions of previously reported drill holes.

Notes on the Calculation of Assay Intervals

  1. “Significant” assay intervals are defined as 1m core length or more of mineralization with an average fire assay result of greater than 0.7 g/t Au, representing the bottom cut-off for high-grade mill feed in the Marathon December 2022 Updated Feasibility Study mine plan. Assay intervals with an average fire assay result of between 0.3 g/t Au and 0.7 g/t Au are above the cut-off used in the July 2022 Mineral Resource estimate for the Berry Deposit but are not considered “significant” for the purposes of this news release.
  2. Cut gold grades are calculated at 30 g/t Au.
  3. No significant results in drill holes VL-22-1264, 1281 and 1284.
  4. Drill hole VL-22-1265A was drilled to 24.9 m and abandoned. It was not sampled.
