SAN BERNARDINO, Calif., April 29, 2026 /PRNewswire/ — Locksley Resources Limited(
ASX: LKY, OTCQX: LKYRF) announced today that its research collaboration with Columbia
University, continues to support the company’s understanding of potential processing
routes for its carbonatite-related mineral systems located at the Company’s Mojave
Project in California.

The research collaboration, being led by Professor Greeshma Gadikota at Columbia’s
Department of Earth and Environmental Engineering and Columbia Climate School, is
focused on developing potential processing pathways for the recovery, separation
and metallization of rare earth elements and associated critical metals from carbonatite
and bastnasite style mineral systems, including the mineralization style relevant
to Locksley’s El Campo REE project within its Mojave Project in the Mountain Pass
region.

"The work completed to date has provided us with alternative processing routes aimed
at simplifying downstream flowsheets that can be evaluated for our project," said
Kerrie Matthews, Managing Director and CEO of Locksley. "The next phase of this 
partnership will use Locksley samples and assess the implications of these results
for future consideration. Of key importance is that this work is being conducted
in parallel with maiden exploration at El Campo, enabling us to better understand
all the potential development pathways as the project advances."

This collaboration is one of several Locksley has in place. Earlier this month the
company reported on its advancement toward production of high purity antimony concentrate
and next-generation materials as a result of its sponsored research program with
Rice University in Texas.

Locksley Resources Limited ([https://www.locksleyresources.com.au](https://www.locksleyresources.com.au/))
is focused on critical minerals in the US. The Company is actively advancing the
Mojave Project in California, targeting rare earth elements (REEs) and antimony.
Locksley is executing a mine-to-market strategy for antimony, aimed at reestablishing
domestic supply chains for critical materials, underpinned by strategic downstream
technology partnerships with leading U.S. research institutions and industry partners.
This integrated approach combines resource development with innovative processing
and separation technologies, positioning Locksley to play a key role in advancing
U.S. critical minerals independence.

The Company’s Mojave Project is located adjacent to MP Materials Mountain Pass Mine
and mill, the only REE producing mine in the United States to date.
