Colosseum Delivers More High Grade Gold Intercepts

Dateline Resources Limited (ASX:DTR) (Dateline or the Company) is pleased to announce further significant gold values from drilling results at the Colosseum Gold Mine in California. The Company currently has a diamond and RC rig operating in the south pit undertaking infill and extensional drilling.

Highlights

• Results received from diamond and reverse circulation (RC) drilling within the south pit, comprising infill and extensional drilling
• Final results from diamond drillhole CM24-16 received, increasing the intercept from 88m to 104.7m:
  • 104.7m @ 3.65g/t Au from 77.23m
    • Incl. 12.2m @ 8.40g/t Au from 108.81m
  • 12.8m @ 2.18g/t Au from 208.17m
• First results from the RC program have been received, with the following significant results:
  • RC24-003 25.9m @ 1.91g/t Au from 57.91m
    • Incl. 3.05m @ 3.05g/t Au from 57.91m
  • RC24-004 3.05m @ 1.92g/t Au from 86.86m 3.05m @ 2.95g/t Au from 94.48m
  • RC24-008 74.7m @ 4.27g/t Au from 77.72m
    • Incl. 27.4m @ 7.82g/t Au from 88.39m
• Updated Mineral Resource Estimate (MRE) underway, with an expected release in early June to be followed by mining studies

Diamond drillhole CM24-16 was first reported in April 2024, with assays returned for the upper portion of the hole (88m @ 4.18g/t Au). The hole was extended to ensure that it finished outside of the sedimentary breccia, with recent assays extending the intersection to 104.7m @ 3.65g/t Au.

The RC drill rig is focused on infill drilling and testing the margins of the existing Mineral Resource. Significant results received to date include 74.7m @ 4.27g/t Au and 25.9m @ 1.92g/t Au.

The Mineral Resource update is currently underway. Results from CM24-16 will be included in this update, however the RC results will be included in a subsequent update later in the year.

Commenting on the study, Managing Director, Stephen Baghdadi, stated:

“These drill hole results are further confirmation that the Colosseum project has delivered consistent gold grades in a wide zone.

“With the updated MRE expected in the next few weeks, we plan to move quickly to determining a mine plan to extract value for our shareholders.”

Drilling Results

Following a scheduled break, the drill crews returned to site and continued drilling within the south pit at Colosseum. The aim of the diamond drilling program is to extend the mineralised zone at depth, below the existing Mineral Resource, whilst the RC program is undertaking infill work as well as better defining the margins of mineralisation.

The RC drilling intersected mineralisation within the sedimentary and felsite breccia units in RC24-003 and RC24-004. Both holes intersected mineralization in more sulphide rich zones containing pyrite, sphalerite, and/or galena >5%.
