Day Dawn Project – Paterson Province

Exploration licence E45/7078 is located 10km to the northwest of the giant, +20Moz Telfer gold mine and covers an area of approximately 20km2

Exploration in the Day Dawn area dates to the 1980s, with multiple companies identifying high‑grade gold across several prospects. Despite the encouraging drill results, definition of consistent, continuous zones of mineralisation proved challenging for previous explorers. Hamelin has completed a comprehensive review and reinterpretation of historical drilling data at Day Dawn and identified coherent, near surface zones of high-grade gold mineralisation. Hamelin believes these high-grade lodes may mark the surface expression of a larger, previously untested mineral system.

Phase 1 RC drilling at Day Dawn will focus on the newly defined Aurora Lode. This sub vertical lode trends in a northeast orientation, starts from surface and contains multiple high-grade gold intersections including:

  • 4 metres at 4.31 g/t Au from 0 metres in ETG0109 including
    • 1 metre at 14.0 g/t Au from 0 metres
  • 7 metres at 17.13 g/t Au from 16 metres in NTR61 including
    • 3 metres at 37.53 g/t Au from 19 metres
  • 6 metres at 19.58 g/t Au from 31 metres in NTR5 including
    • 4 metres at 28.97 g/t Au from 31 metres
  • 3 metres at 51.12 g/t Au from 35 metres in NTR57 including
    • 2 metres at 76.25 g/t Au from 35 metres and
  • 2.5 metres at 7.65 g/t Au from 127.1 metres to end of hole in ETG0053 including
    • 0.45 metres at 25.40 g/t Au from 129.15 metres to end of hole

The exploration model developed for Day Dawn is similar and strongly influenced by geological setting of the nearby Telfer gold-copper deposit. At Telfer, gold mineralisation is concentrated within conformable and discordant reef style lodes and broader zones of stockwork mineralisation.

The geological setting at Day Dawn is interpreted to be similar to that seen at Telfer. The majority of mineralisation found to date at Day Dawn is hosted within the Outer Siltstone unit.  The bulk of the gold mineralisation at Telfer sits stratigraphically lower in the sequence within the lower Telfer and Upper Malu Members.

The 3D image above is a schematic representation of the potential mineralisation styles and stratigraphy at Day Dawn. Hamelin’s initial phases of RC drilling will focus on the discovery and definition of the near surface, high grade lodes in the Outer Siltstone unit.  An EIS co-funded diamond drilling will target gold mineralisation in the lower Telfer and Upper Malu Members.  The structural and geological information gathered from the RC drill program will heavily influence the location of the EIS diamond drill holes.
