Legend Mining strikes multiple massive nickel-copper sulphides at Mawson

Legend Mining massive sulphide intersections Mawson ASX LEG nickel copper mineralisation
Legend Mining hailed its latest Rockford project drilling results as the most significant find in the region since the world-class Nova discovery.

Legend Mining (ASX: LEG) has uncovered multiple intersections of massive sulphide mineralisation at the Mawson discovery within its Rockford nickel and copper project in Western Australia’s Fraser Range.

The company today emerged from a trading halt to reveal five intervals of significant nickel-copper sulphide mineralisation totalling 41.5m from the first diamond hole drilled at Mawson this year.

Massive sulphides were intersected over three intervals (totalling 25.3m), with semi-massive, heavy disseminated and massive sulphides intersected at a fourth, and heavy disseminated to semi-massive sulphides in a fifth interval.

Legend managing director Mark Wilson described the results as a “spectacular start” to the 2020 field season.

“The three massive sulphide intercepts clearly stamp this hole as the most significant and exciting discovery in the Fraser Range post Nova,” he said.

Mr Wilson said a downhole electromagnetic survey and structural analysis of the drill core is currently being undertaken and will facilitate the design of a drilling program to further delineate the mineralisation.

“Samples for assay will be sent to the laboratory following the completion of the structural analysis and results are expected two to three weeks thereafter,” he said.

“Meanwhile, the diamond rig has relocated to drill the next hole under the discovery air core hole RKAC151. We look forward to updating the market as new results come to hand,” Mr Wilson added.

Nova-style mineralisation

Located within Legend’s Rockford project, Mawson was confirmed as a discovery in January following assay results from three diamond drill holes and a structural report by Model Earth PL, with mineralisation starting at a relatively shallow depth of 76m.

The primary target of the company’s exploration program is Nova-style nickel-copper mineralisation, with secondary targets including VMS style zinc-copper-lead-silver mineralisation.

The Nova nickel deposit, located about 15km of the Rockford mining lease, was discovered in 2012 and has been commercially mined by IGO (ASX: IGO) for more than 2.5 years.

During the 2019 financial year, the mine produced 30,708 tonnes of nickel in concentrate, 13,693t of copper concentrate and 1,090t of cobalt concentrate.

COVID-19 response

In today’s update to the market, Legend said it has been proactively managing the potential impact of COVID-19, developing systems and policies to ensure the health and safety of its employees and contractors, as well as limiting risk to its operations.

Some of its measures to minimise the risk of infection and rate of transmission include employees and contractors completing a COVID-19 exposure questionnaire, increased hygiene practices and restrictions on non-essential travel.

The company said it has also established strong infection control systems and protocols across the business and is facilitating remote working arrangements, where practicable.
