Magnum Mining and Exploration Limited (ASX:MGU) has reached a regulatory milestone at its wholly owned Parker Gold-Copper Project in Arizona, with the US Bureau of Land Management (BLM) confirming that the company’s exploratory drilling Notice is complete.

Magnum Mining shares traded flat at AUD 0.0080 during the morning trading session on 20 August 2026, while the company remained down 20.00% over the past year. The update outlines progress towards planned first-pass drilling, with Magnum now preparing to complete the required financial guarantee process and final drilling preparations.

The Parker Gold-Copper Project is located in La Paz County, Arizona, within the Walker Trend, a region that the company states hosts gold, silver, and copper occurrences. Magnum is focused on advancing the project through exploration activities designed to test identified gold-copper targets.

Parker Project Clears BLM Regulatory Milestone

The BLM’s Lake Havasu Field Office has completed its review of Magnum’s exploratory drilling Notice for the Parker Gold-Copper Project and determined the submission to be complete.

The BLM assigned the Notice serial number AZAZ106803823 and determined the required reclamation financial guarantee. The regulator also recorded that the proposed activities would not cause unnecessary or undue degradation.

The Notice will remain in effect for two years, subject to applicable requirements.

Magnum said the completion of the regulatory process represents a step towards its planned first-pass drilling campaign at Parker.

Exploration Work Defines Multiple Target Corridors

Magnum has completed several exploration workstreams at Parker to refine drill targets and reduce geological uncertainties ahead of drilling.

The work completed includes selective surface sampling, systematic soil sampling, geological and structural mapping, and integrated magnetic, radiometric, and three-dimensional geophysical interpretation.

The company has identified approximately 5 kilometres of combined prospective strike across three key areas: Eagle Nest, Red Breccia, and NSW Detachment.

The identified strike lengths include approximately 1.3 kilometres at Eagle Nest, 2.4 kilometres at Red Breccia, and 1.1 kilometres at NSW Detachment. Magnum noted that these strike lengths represent exploration-scale target corridors and do not demonstrate continuous mineralisation.

Previous Gold-Copper Sampling Supports Drill Targets

Previously reported selective rock-chip sampling identified multiple high-grade gold-copper results across the three exploration corridors.

Reported results include:

  • 178g/t gold and 18.30% copper from Sample 51101
  • 91.6g/t gold and 6.39% copper from Sample 51013
  • 142g/t gold and 0.16% copper from Sample 51059
  • 37.5g/t gold and 12.85% copper from Sample 51028
  • 38.0g/t gold and 4.44% copper from Sample 51095

Additional samples returned gold and copper results across the identified target areas.

The company stated that first-pass drilling will be designed to assess whether surface mineralisation and interpreted geological structures continue at depth.

Magnum noted that the reported rock-chip samples are selective point samples and are not representative of mineralised width, average grade, volume, or continuity.

Next Steps Towards Initial Drilling

Following completion of the BLM review, Magnum intends to complete the required financial guarantee process and progress preparations for initial drilling.

The company plans to conduct first-pass drilling at Parker, subject to regulatory and operational requirements.

Managing Director Antonio Vitor said Magnum’s exploration strategy is focused on advancing projects with discovery potential towards drill testing.

“Parker is a clear fit, supported by strong surface mineralisation and extensive technical work completed to date,” Antonio Vitor said.

He added that the company was progressing Parker towards first-pass drilling following completion of the BLM milestone.

Investor Takeaway

Magnum Mining’s latest update focuses on regulatory progress at the Parker Gold-Copper Project, with the completion of the BLM Notice review allowing the company to move towards drilling preparations. The company has identified multiple exploration corridors supported by previous geological work and surface sampling results.

Investors may continue to monitor completion of the financial guarantee process, commencement of first-pass drilling, and future exploration results from the Parker Project.
