Delta continues to hit gold with drilling near Thunder Bay

Apr 10, 2024


"We continue to be impressed with our drill results at Delta-1. So far, in 2024, with each new drill hole, we are adding to our gold inventory at Delta 1," said Tessier, President and CEO.  "The gold zones continue to show widths, continuity, and homogeneity near surface, adding to the potential for an open-pit operation; while higher grade intercepts of 7.46 g/t gold over 3.5 metres and 3.16 g/t gold over 2.2 metres suggest underground potential at depth. The drill program is still underway, and we look forward to more results shortly."

Delta Resources Limited is pleased to provide final assay results for six (6) drill holes, and one (1) drill hole extension, from its ongoing 2024 drill campaign at its 100% owned Delta-1 Gold project in Thunder Bay. The holes reported total 2,041.6 metres. 

The objective of this drill campaign is twofold:

  1. To fill in gaps from Delta's previous drilling within a mineral envelope already identified within a 2-kilometre strike and 250 metre vertical depth to further increase the overall mineral inventory and,
  2. Exploration drill holes to the east, west and further depths to demonstrate the potential of significantly expanding the mineral envelope. 

Highlights:

  • Drill Hole D1-24-96 intersected 1.64 g/t gold over 29.5 metres, Incl. 7.46 g/t gold over 3.5 metres,
  • Drill Hole D1-24-95 intersected 1.42 g/t gold over 24.1 metres and 1.68 g/t gold over 9.0 metres,
  • Drill Hole D1-24-93 intersected 3.71 g/t gold over 3.2 metres,
  • Drill Hole D1-24-94 intersected 0.64 g/t over gold 43.0 metres,
  • Drill Hole D1-24-17ext intersected 1.18 g/t gold over 12.0 metres.

Complete results from the six (6) drill holes and one (1) drill hole extension are provided in Table 1 below. The 2024 drill campaign is ongoing, currently drilling hole D1-24-109 with final assay results still pending.

Detailed Results:

  • Drill hole D1-24-96 (figure 2) was designed to test the down-dip extension of the Gold Zone 60 metres down-dip from drill hole D1-24-92 (see below), 100 metres down-dip from a first intercept of drill hole D1-22-37 (0.37 g/t Au over 104.6 metres) and 50 metres down-dip from a second, deeper intercept of drill hole D1-23-37 (2.06 g/t Au over 17.5 metres). The hole intersected both zones with a first intercept of 0.36 g/t Au over 17.5 metres and a second intercept of 1.64 g/t Au over 29.5 metres. This second intercept includes a high-grade section of 7.46 g/t Au over 3.5 metres at a vertical depth of approximately 285 metres.
  • Drill Hole D1-24-92 (figure 2) was designed to intersect the gold zone 60 metres down-dip from the intercepts of drill holes D1-21-09 (1.25 g/t Au over 18.0 metres) and D1-22-37 (0.37 g/t Au over 104.6 metres). The hole intersected 1.42 g/t Au over 6.2 metres at the contact of a feldspar-porphyry dike.
  • Drill hole D1-24-95 (figure 3) was designed to test the Gold Zone 60 metres down-dip from the intercept of drill hole D1-23-30 (2.06 g/t Au over 65.8 metres and 0.74 g/t Au over 19.0 metres). The drill hole intersected several mineralized zones between 56.6 and 236.5 metres Intercepts include: 0.76 g/t Au over 24.9 metres, 0.85 g/t Au over 7.65 metres, 0.43 g/t Au over 14.0 metres, 1.68 g/t Au over 9.0 metres and 1.08 g/t Au over 36.8 metres.

  • Geological Discussion

    The Delta-1 project is located in the Shebandowan Greenstone Belt and covers a 19 km strike extent of the Shebandowan Structural Zone. Gold mineralization at Eureka, occurs within a broad corridor of highly altered (ankerite-calcite-silicification and albitization) rocks exhibiting highly anomalous gold values of up to 0.2 g/t gold. Higher-grade mineralization within this corridor is associated with a stockwork of quartz-ankerite-pyrite-gold veinlets, with increased density of these veinlets generally proportional to increased gold grade. The gold mineralized zones have so far been intersected for a strike of approximately 2.3 kilometres, with a higher-grade segment extending for nearly 950 metres. So far, the mineralized zone extends from surface to a vertical depth of approximately 250 metres. Mineralization strikes approximately 100 to 120 degrees azimuth, with a dip of 75-80 degrees north (shallower dips of 50N are observed in the western portion of the zone). Higher-grade, wide ore shoots are observed and appear to be plunging approximately 40 degrees towards the west, within this structural corridor. Similar ore shoots are often observed in structurally controlled gold deposits and often occur with a certain periodicity. The currently defined ore shoots are open at depth. 

    Analytical Protocol and QA/QC

    Chemical analyses reported in this press release were performed at AGAT Laboratories. AGAT Laboratories is accredited to ISO 17025 by the Standards Council of Canada (SCC). Sample preparation was performed in Thunder Bay, Ontario. Sampling and analytical procedures are subject to a comprehensive Quality Assurance and Quality Control program that includes duplicate samples, blanks, and analytical standards.

    The following assaying protocol was adopted at Delta-1 to reduce the assay variability due to nugget effect caused by visible gold:

  • If visible gold is observed in the sample or within the assumed mineralized zone, the assay is performed by Metallic Screening whereby the entire sample is crushed, a 1 kg portion is pulverized and screened to 106µm and analyzed by 50 g fire assay with gravimetric finish at the AGAT Laboratory in Thunder Bay, Ontario. 
  • If no visible gold is observed or outside of the mineralized zones, an initial assay is performed by 50 g Fire Assay with ICP-OES finish at the AGAT Laboratory in Thunder Bay, Ontario. If the assay result exceeds 2.0 g/t gold, remaining rejects are pulverized, a 1 kg portion is screened to 106µm and analyzed by 50 g fire assay with gravimetric finish at the AGAT Laboratory in Thunder Bay, Ontario. 

  • NQ-size drill core was sawed in half lengthwise and half of the core was sampled and sealed in clean plastic bags before being shipped for assay. The remaining half of the core was replaced in core boxes and is stored at Delta's core storage facilities. Standards and blanks are inserted in the sequence of samples on site as quality assurance and quality control in addition to the regular insertion of blank, duplicate, and standard samples accredited by SGS Canada Minerals Laboratories during the analytical process.
