Grade Control Program At The Hammerdown Gold Project

TORONTO - Maritime Resources Corp. reported on grade control drill program at the Hammerdown Gold Project. Hammerdown is located in the Baie Verte mining district of Newfoundland and Labrador, near the towns of King's Point and Springdale.

The latest drill results cover the central portion of the proposed first year of open pit mining at Hammerdown. The grade control program continues to confirm the vein model and location of the historic underground workings while identifying additional mineralization between the high-grade veins, mine backfill material and remnant pillars. Notable assay results include drill hole HDGC-25-177 which intersected 5.5 gpt Au over 29.8 m, including 73.0 gpt Au over 1.5 m related to a group of mineralized quartz veins and altered mineralized quartz feldspar porphyry (QFP) within the unmined crown pillar. Drill hole HDGC-25-160 was drilled 20 m south of drill hole HDGC025-177 and returned 7.7 gpt Au over 5.6 m. Drill hole HDGC-25-188, located 20?m north of previously reported HDGC-25-118 (27.9?gpt Au over 1.0?m; see Maritime press release dated March 14, 2025), returned several high-grade gold intercepts. Highlights include 15.0?gpt Au over 1.4?m, 67.1?gpt Au over 0.9?m, and 14.6?gpt Au over 0.2?m.

The Hammerdown grade control program has identified high grade gold mineralization within the historic backfilled stopes. Drill hole HDGC-25-189 returned 14.8 gpt Au over 5.9 m and HDGC-25-175 returned 17.0 gpt Au over 4.4 m. These results enhance the confidence in the mineralization surrounding and inside the previously mined out stopes at Hammerdown. All backfill intervals drilled during the grade control program were sampled and resulted in the collection of 151 samples representing 274 linear metres of drilling with a weighted average of 3.3 gpt Au across a 1 m composite length. The backfill gold content is believed to be the result of a combination of the high historic mine cut-off grade as well as high grade loss on mining material remaining during the cut and fill mining process. The potential quantity and grade of the backfill material are conceptual in nature and there has been insufficient sampling to define a mineral resource. It is uncertain whether further sampling would result in the backfill material being delineated as a mineral resource.

The grade control drill program completed 8,460 metres of diamond drilling in 273 drill holes. The program was designed to intersect the sub vertical mineralization on a 10 m x 10 m staggered pattern to maximize future ore extraction while minimizing ore losses and dilution. Assay results will be released as they become available.
