Delta Resources begins next phase of 2024/25 exploration at Delta-1 in Thunder Bay
Delta Resources Limited is pleased to provide a corporate update as it begins its next phase of exploration at the newly expanded Delta-1 Project in Thunder Bay.
In October 2022, Delta released the results of its discovery drill hole at the Eureka Gold Deposit (see Press release October 31, 2022) at its wholly owned Delta-1 project (drill hole D1-22-18: 5.92 g/t gold over 31.0 metres, including 14.80 g/t gold over 11.9 metres). The deposit is located approximately 50 kilometres west of the port city of Thunder Bay, Ontario, within close proximity of the Trans-Canada Highway, where abundant infrastructure already exists including power lines, railway tracks and easy year-round road access. Since that time Delta carried out an aggressive drilling program and has now completed 115 drill holes totalling 35,575 metres, including the initial seventeen (17) exploration drill holes before the discovery hole was reported.
Since the discovery hole, the objective of every follow-up drill campaign has been to expand the deposit size to the east, west and at depth, and therefore with the objective of increasing Delta's gold inventory at Eureka, while gaining valuable insight on the controls of the gold mineralization. Delta has now extended the deposit to a strike length of over 2.5 kilometres and a vertical extent from surface to a vertical depth of 300 metres.
Although the Eureka Gold deposit remains at a very early exploration stage, its geological setting, mineralization style and alteration are all reminiscent of the near-surface expression of the Canadian Malartic Deposit located west of Val D'Or, Quebec.

The technical team at Delta has integrated all the latest drill data from the first half of 2024 to the current geological 3D model. The team also began a property-scale exploration program to identify new targets on the newly expanded property that now covers a commanding 306 square kilometres of the eastern and central portion of the Shebandowan Greenstone Belt and approximately 35 kilometres of strike length.
Eureka Zone Exposed at Surface
Over the course of the 2024 summer exploration program, Delta was able to expose an eleven (11) metre section of the Eureka Gold Deposit at surface through mechanical trenching (Photo 1).
The exposed section is located above the trace of drill holes D1-23-60 (1.79 g/t Au over 128.5 m), where overburden thickness was estimated to be manageable for excavators. The overburden thickness varied between 2.5 and 3.0 metres and the trench was halted when the thickness exceeded 3.0 metres. In all, the trench exposed a total of 11 metres of the zone across strike. A channel 4 cm wide was cut with a rock saw, averaging 8 cm deep for sampling. The zone was divided in 11 equal samples of 1 metre in length and sent to assay. The complete eleven metres of channel samples returned an average grade of 1.23 g/t Au.
Although the drilling data already clearly indicated that the mineralization is present at surface, this new trench provides Delta's geologists with enhanced geological and structural information.

A Commanding Land Position with Potential for Multiple Deposits
Since July 2023, Delta has acquired the exclusive rights to several important and strategic exploration properties adjacent and contiguous to the Eureka Gold deposit with the aim of having a commanding land position in the eastern portion of the Shebandowan greenstone belt. Delta now controls an area covering over 30,600 hectares. The Delta team believes that these acquisitions hold excellent potential for additional gold deposits within proximity to each other. There are no work commitments on any of the properties acquired by Delta allowing the geological team to plan and prioritize its exploration campaign from technical driven data exclusively.
