Legend Mining enhances Rockford potential with new strong EM conductor at Hurley prospect

A regional aircore drilling program comprising 250 holes for 16,000 metres is underway on the western portion of the Rockford Project to test a combination of aeromagnetic and gravity features.

Legend Mining Limited - Legend Mining identifies strong electromagnetic conductor at Hurley prospect within Rockford Project
The extensive aircore program is expected to take two months

Legend Mining Ltd (ASX:LEG) has identified a new, strong electromagnetic (EM) conductor at Hurley prospect which enhances the potential of the Rockford Project on WA's Fraser Range.

This third conductor defined at Hurley is supported by a geochemical review with a new regional aircore drilling program comprising 250 holes for around 16,000 metres that is now underway to include Hurley.

Moving loop electromagnetic (MLTEM) surveying was originally completed over the Worsley, Crean and Hurley prospects within the Rockford South region in May 2020.

These surveys have targeted a combination of aeromagnetic and gravity features and identified conductors W1 (Worsley), C1 (Crean) and H1- H2 (Hurley).

Further infill surveying was then carried out at Hurley over the H1-H2 conductors, which aimed to provide additional data to enable accurate modelling of the features.

This surveying identified the new strong conductor, H3, in the southern part of the prospect.

Both the H1 and H3 conductors are considered priority targets based on their modelled conductance, dimensions and association with aeromagnetic features.

“Positive results” from regional work

Managing director Mark Wilson said: “In addition to Mawson, it is pleasing to see positive results from our regional work with a third conductor defined at Hurley.

“A recently completed project-scale geochemical review has also highlighted Hurley as a highly ranked geochemical prospect.

“This further enhances the prospectivity of the entire Rockford project and shareholders should also note that the Hurley prospect is on 100%-owned Legend ground.”

Further aircore drilling planned

A recently completed geochemical review of the historical aircore drilling across the Rockford Project, including Mawson, highlighted Hurley as a highly ranked geochemical target, falling within the 90th percentile of ranked data.

Further aircore drilling is planned over these three conductors to test for anomalous geochemistry and provide information on bedrock lithologies prior to possible RC and diamond drill testing.

The Crean conductor requires aircore follow-up to define the extent of previously identified anomalous nickel-copper geochemistry.

Drilling to test 12 aeromagnetic features

An extensive aircore drilling program comprising 250 holes for 16,000 metres has begun focusing on the western portion of the Rockford Project.

The drilling will test a combination of 12 aeromagnetic and gravity features, interpreted to be related to mafic and ultramafic intrusives with the aim being to identify anomalous nickel-copper associated with intrusive host rocks for follow up MLTEM surveying and RC and diamond drill testing.

It is expected to take two months to complete, with Hurley and Crean given priority.
