Dateline Appoints GenCap to Lead Colosseum Financing

SAN BERNARDINO, CA / ACCESS Newswire / May 19, 2026 / Dateline Resources Limited (ASX:DTR,OTC:DTREF)(OTCQB:DTREF)(FSE:YE1) (Dateline or the Company) is pleased to announce the appointment of Vancouver-based GenCap Mining Advisory (https://www.gencapmining.com) to lead the financing process for the Colosseum Gold Project in San Bernardino County, California. GenCap's team, led by Marcus Chalk, has nearly thirty years' experience of working together on corporate finance transactions.

GenCap has been mandated to manage the existing financing process and identify additional suitable financiers. It is envisaged that given the extensive amount of information that has recently been prepared for the Bankable Feasibility Study (BFS), the due diligence process should be expedited, and proposals can be reviewed relatively quickly.

The BFS was designed with accelerated mining and processing of higher-grade material, increasing cashflows in the earlier years of the project, resulting in a short payback period. The Company is confident that the strong operating margins and short payback period will be attractive to financiers.

Dateline's Managing Director, Stephen Baghdadi, commented:

"The Colosseum BFS demonstrated a high margin gold project with upside from both a higher gold price as well as potential mine life extensions via the exciting Northeast Extension zone of mineralization. The mining and processing schedule was optimized to deliver maximum cashflow generation in the first half of the project, an attractive feature when seeking finance.

"We look forward to completing the financing of Colosseum and moving into the construction phase as soon as practicable."

This press release has been authorized for release by the Board of Dateline Resources Limited.
