Establishing the Hurricane Antimony Project
In early 2014
A preliminary activity field trip into the western extent of the Project Area was completed to ground proof the Holmes Anomaly (gold antimony), which was first discovered in 1988 by Sanworth Pty Ltd/Hawk Investments Ltd (ATP4259 CRN19844).
In late 2014
Innovative and modern aerial photography technology was deployed over the Project Area. The Hurricane Range between the Retina Fault and the Hurricane Fault was used to map and plan a safe entry into the region, and to further identify prospective structures.
It showed the Holmes Anomaly (120m x 60m 13 rock chips up to 21.2 g/t Au and 20.8% Sb).
A ground proofing preliminary activity field trip was undertaken, and confirmed the discovery of three new structures:
A scoping study was prepared for an ‘Advanced Activity Drilling Program’ to target the high-grade zones in both the Holmes and Tornado prospects, with the following undertakings and results being achieved:
An ‘Access and Compensation Agreement’ was executed with the Landholder to facilitate access track preparation and the drilling program,
‘Cultural Heritage and Native Title Protections’ were negotiated and cleared,
An access track was developed into the Tornado prospect,
A 15kg bulk sample of oxidised ore taken from the Holmes prospect returned a grade of 9.2g/t,
A 60kg bulk sample taken from the Tornado prospect had a grade of 4.2g/t,
The process test work confirmed:
– VSI crushing to P100 600um was achieved with a recirculating load of 480%,
– Gold concentration via gravity was not viable,
– Gold concentration via flotation was moderately successful, achieving 67.0% gold recovery into 6.3% of the mass, or 85% recovery into 22% of the mass,
– Gold recovery via leaching was successful, and showed:
i. Leach test work on the P100 150um flotation concentrate resulted in 92.9% recovery in 1 hour, 95.4% in 2 hours and 99.7% in 12 hours,
ii. Leach test work on a typical sample of ROM ore, VSI crushed to P100 600um resulted in 82.6% gold recovery in 1 hour, 89.0% in 2 hours and 91.4% in 6 hours,
iii. There was nothing found in the way of deleterious elements that could affect leaching or downstream processing.
A JORC compliant exploration program initially defined a 1,500,000t resource before making a further staged progression:
As a development project with the aim to increase the JORC confidence and progress development studies and approvals on a 1.5Mt and 250,000oz project,
As a combination of both.
