Updated Mineral Resource Estimate (MRE) underway, with an expected release in early June to be followed by mining studies
Dateline Resources Limited ( 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.
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.”
ASX Release 16 May 2024
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%.
Recent results include the following:

Mineral Resource Estimate
The Company has engaged H&SC Consultants Pty Ltd to update the Mineral Resource Estimate (MRE) for the Colosseum gold deposit. The existing MRE of 20.9Mt @ 1.2g/t Au for 813koz gold that was previously completed and announced to the market in July 2022, was based entirely on historical drilling undertaken by previous operators.
The updated MRE will include all of the diamond drilling undertaken by the Company since the project was acquired in 2021. The results for the recent RC drilling were received after the cut-off date for the MRE and will be incorporated into a further update later in 2024, which will also include any diamond and RC results completed during the next 4-6 months.
Mining Studies
The updated MRE, expected in June 2024, will be used as the basis for the Company to investigate the potential feasibility of re-commencing production at the Colosseum mine, using open pit mining methods, in accordance with the approved Plan Of Operation. The Company may also consider the feasibility of pursuing lower cost underground bulk mining techniques for the sections of the breccia pipe that have returned higher grade gold intercepts.
