MT BERGHAUS GRAVITY SURVEY DELINEATES COMPELLING NEW DRILL TARGETS
Located north and proximal to the 11.2m ounce HEMI deposit (ASX: DEG)
Highlights • A high resolution ground-borne gravity survey completed which has delineated 4 compelling new drill targets in proximity to extensive “gold halos” from prior drilling • WA Government Exploration Incentive Scheme (EIS) grant submitted Mantle Minerals Limited (ASX:MTL) (“Mantle”) (“the Company”) is pleased to advise that it has received the results from the Gravity survey conducted at the Mount Berghaus tenement E45/ 5899. The Company has completed significant work over the project including commissioning high resolution aeromagnetics, air core drilling and reverse circulation programs focused on magnetic and structural targets. Drilling from these programs intersected Mallina Formation sediments along with dioritic and felsic intrusives which have generally returned geochemically anomalous gold. More recent drilling in the south-east of the project defined elevated gold over an 800m trend, with best intercepts returning 12m @ 1.37g/t Au, 32m @ 0.16g/t Au and 5m @ 1.10g/t . (ASX:MTL Release 25/11/2024). A high-level review of the project completed by CORE Geophysics in December 2024, interpreted various magnetic trends parallel to the Mallina/Berghaus shears across the project along with discrete magnetic responses of interest. In order to further refine these responses a high-resolution gravity survey was commissioned to define the significance of these responses and prospectivity for mineralisation. The review has delineated four key gravity targets (refer figure 1). MTB_T1 and MTB_T2 have the appearance of magnetic intrusives and have not been drill tested. MTB_T3 located to the east and close to themineralised drilling is interpreted to represent alteration within the sediment. MTB_T4 provides a discrete gravity response aligned along an interpreted magnetic structure. Depth modelling indicated all drill targets are relatively shallow beneath cover.
