Eastern Metals Limited announced that the data from last year's gravity survey at Browns Reef has now been processed and interpreted. The new survey data has been merged with existing data1 collected by a previous holder of the project tenement. The merged data set covers most of the prospective areas within the licence area.

The combined data set shows a clearly defined anomalous gravity trend that maps the prospective Preston formation and the hydrothermal breccia on its footwall. This zone contains the base metal sulphide mineralisation that has been drilled over a strike length of more than 6 kilometres. The central 2,700 metre part of this zone has been drilled in more detail.

Recently EMS has focussed on a smaller part of this area known as the Evergreen zone, which the Company's 2022 drilling has shown contains higher grade, zinc-dominated, polymetallic mineralisation. The gravity survey clearly maps the main trend of the mineralisation and has also shown other anomalies with similar character that could also be associated with mineralisation. An aircore drilling program has been planned to test these anomalies and other prospective structures.

Browns Reef is a polymetallic lode of largely stratabound base metal sulphide mineralisation developed in the Late Silurian Preston formation, 5 kilometres west of Lake Cargelligo in the Cobar basin. The mineralisation lies above a hydrothermal breccia unit and closely follows a structure known as the Woorara fault. The mineralisation is known to have a strike length of at least 6 kilometres.

The central 2.7-kilometre zone has been drilled in some detail in the past. Eastern Metals has focussed to date on a higher-grade area known as the Evergreen zone, and intends to do more drilling here in 2023, and in the nearby Pineview zone, once access is secured. Several linear features can be recognised in the gravity data.

These include a series of gravity "highs", as well as zones having the character of contacts between rock units of higher and lower density ­ in other words, "contact features". This map also shows the locations of the Evergreen and Pineview zones, where the Company intends to do further diamond drilling in 2023. The area from a few hundred metres to the north of Evergreen and to a few hundred metres to the south of Pineview is the 2.7-kilometre zone, which has been drilled in some detail in the past.

There has been no deep drilling that has tested the gravity anomalies to the north and south of this zone, as well as those to the west, and only a limited amount of shallow drilling. The holes planned at Evergreen, along with holes drilled by a previous owner of the tenement, are expected to allow for a JORC 2012-compliant identified mineral resource estimate to be made.
