Marble Bar

On 22 April 2026, GL1 has entered into a binding Tenements and Mineral Rights Sale Agreement with Jiangsu Lopal Tech. Group Co., Ltd – a leading global battery materials producer listed on the Shanghai and Hong Kong stock exchange – for the sale of GL1’s interest in its Marble Bar Lithium Project for a total consideration of A$14.85 million.

This divestment aligns with GL1’s strategy to focus its resources and capital on the accelerated development of its flagship Manna Lithium Project, while also generating non-dilutive funding.

For background, The MBLP is located in one of the world’s major hard-rock lithium provinces, the region hosts the world-class Pilgangoora (owned by Pilbara Minerals Limited, ASX: PLS) and Wodgina deposits (owned in joint venture between Albemarle and Mineral Resources Limited, ASX: MIN). The MBLP exhibits spodumene bearing pegmatite intrusives within the project area greenstone, which is a similar geological setting to that as seen in those nearby lithium deposits.

The MBLP is located in a well-established mining region with access to infrastructure. The sealed Marble Bar Road that connects Port Hedland to Marble Bar traverses the tenement area.

In December 2022, the Company reported an upgraded JORC 2012 Mineral Resource of 18.0Mt at 1.0% Li₂O. The upgrade was a 71% increase on the maiden JORC 2012 Mineral Resource of 10.5Mt at 1.0% Li₂O declared in June 2020.

Lithium mineralisation at the Marble Bar Lithium Project has been identified over 15km.  The project area, whilst largely untested, is also highly prospective for gold and base metal mineralisation, presenting further growth opportunities to investigate.
