First Two Step-out Holes Extend High Grades at Horden Lake

Pivotal Metals Limited (ASX:PVT) (‘Pivotal’ or the ‘Company’) is pleased to provide the assay results of two further drill holes from its 2024 diamond drill program completed at its 100% owned Horden Lake Project in Quebec, Canada.

Highlights

• High grade copper mineralisation extended down-plunge in hole HN-24-97, the first step-out hole reported from the 2024 drill program.
  • 21.5m @ 0.98% CuEq¹ (0.56% Cu, 0.12% Ni, 0.07g/t Au, 0.09g/t Pd) plus additional 0.03g/t Pt, 119ppm Co, 8.3g/t Ag from 266.1m
    Including 7.2m @ 1.56% CuEq from 280.4m
  • Deepest hole in this zone, 80-110m diagonally down-plunge from the two nearest historic holes
• HN-24-96 extends downwards and infills high grade mineralisation in 130m gap between previously drilled holes.
  • 17.1m @ 0.58% CuEq (0.25% Cu, 0.1% Ni, 0.03g/t Au, 0.06g/t Pd) plus additional 0.03g/t Pt, 95ppm Co, 3.9g/t Ag from 203m
    Including 5.1m @ 0.95% CuEq from 206.6m
  • 11.9m @ 1.39% CuEq (0.42% Cu, 0.33% Ni, 0.03g/t Au, 0.13g/t Pd) plus additional 0.04g/t Pt, 230ppm Co, 4.8g/t Ag from 229.7m.
    Including 7.8m @ 2.1% CuEq from 229.7m
• Mineralisation now defined to 200-230m vertical depth in the vicinity of these holes. This is less than half the ~550m depth that mineralisation has been defined to in the central part of Horden Lake.
• Significant gold, silver, palladium, platinum and cobalt metals delineated once again, which were not assayed in this part of the deposit during previous drill campaigns.
• Consistent news-flow ahead, including results from the remaining 5,780m / 28 diamond drill holes and downhole EM surveys to be released, followed by a mineral resource update and metallurgical test-work in H2.

Managing Director, Mr Fairhall said:

“Down plunge extensions are a key pillar of the significant upside story at Horden Lake. The southern flank of the deposit has only been drilled to around 200m, whereas mineralisation is defined to ~550m in the central portion. These high grade results in the south demonstrate the strong potential for resource growth at depth, with the deposit remaining completely open across its full strike extent. In addition, we anticipate increasing the metal content of the resource through inclusion of the significant palladium, gold, cobalt, platinum and silver assays we are seeing which were never before assayed for in this portion of the deposit.

We have a significant amount of news-flow in the pipeline as we release further assays and the results of downhole surveys as they become available.”

Overview

Horden Lake is a copper dominant Cu-Ni-Au-PGM-Co Project located 131km north-northwest of Matagami, in Quebec Canada. The Project hosts an indicated and inferred mineral resource estimate of 28mt at 1.5% CuEq, as a result of over 52,464m of drilling already completed on the property. Pivotal has recently completed a 7,097m / 34 hole diamond drilling campaign. 705m / 4 holes have been reported prior to this announcement.

The objectives of the drilling program were to infill missing by-product multi-element assay information, target resource expansion potential (which remains open at depth across its full extent) and collect a distribution of metallurgical sample for a complete test work program. Downhole EM surveys have also been completed to dimension future exploration potential and targeting.

Drill Hole Discussion

Holes HN-24-96 and HN-24-97 were designed to test step out and infill the deeper extensions in the southern portion of the Horden Lake deposit. Table 1 contains the significant intersections, and Figure 2 is a longitudinal section showing the spatial distribution of historical and new drill hole pierce points.

Table 1: Significant intersections. Lower cut 0.3% CuEq over 1.5m (max dilution 5m). Higher cut 1.1% CuEq over 1.5m (5m max dilution).

Hole HN-24-97 is located 140m down-plunge from the 2024 hole HN-24-95 (refer ASX announcement 16 May 2024), and 80m and 110m respectively diagonally down-plunge from holes previously drilled holes H25315 and H26812. Mineralisation falls within one wide intersection of 21.45m grading 0.98% CuEq (0.56% Cu, 0.12% Ni) from 266.1m (Figure 3). Higher grade intersections include 7.17m grading 1.56% CuEq (1.10% Cu, 0.13% Ni) from 280.38m, which includes 4.53m grading 2.05% CuEq (1.48% Cu, 0.18% Ni) from 282.15m. Mineralisation between 266.1 to 282.85 occurs within meta-pyroxenites, meta-gabbros, and mafic dykes and one semi massive sulphide zone. The highest grade zone, 282.85 to 287.55 m occurs within the metasediments with one massive sulphide mineralisation and included a single assay of 4.08% copper over 0.66m at 282.85m. Whilst an inferred zone of mineralisation above 0.3% CuEq was interpreted in this zone, no higher grade zone extended to this area and this intersection shows very encouraging extensions of high grade mineralisation at depth.
