St George Mining Limited provides update on East Laverton Project

St George Mining Limited provide a further update on the major reconnaissance gold drill programme at its 100% owned East Laverton Project in Western Australia.

The drill programme is testing hydrothermal gold targets that include established gold prospects as well as new targets generated by the comprehensive review completed earlier this year.

The targets chosen are part of a portfolio of gold targets across the greenstone belt within the large 2 000 sq/km East Laverton project. Extensive hydrothermal alterations have been discovered by drilling across the East Laverton project area. This indicates a larger fundamental structure that appears to control much of the nickel sulphide mineralization within the project area. Numerous drill holes have encountered widespread hydrothermal alteration, late felsic porphyry intrusives and dolerites, and sulphide mineralisation. The presence of large hydrothermal systems is encouraging for the potential of gold mineralisation.

St George Mining Executive Chairman, John Prineas said:

“The gold drill programme has identified a large hydrothermal system at East Laverton, and assays received to date have already confirmed zones of significant gold anomalism at Cambridge and Cambridge North. “Assays for the remaining targets are pending. These targets have strong gold prospectivity recognised from soil surveys and shallow drilling. The current drill programme will assess if this gold anomalism is associated with primary gold mineralisation.”

The first phase of the 2017 gold drill programme has concluded with a total of 115 drill holes completed for 8 072 m of remote control drilling. The final targets drilled in the programme were at Desert Dragon, Green Dragon and Athena projects.

Eleven drill holes were completed at Desert Dragon, where at least one hole intersected mineralisation at 6 m, discovering 0.70g/t of Aluminum, coming into 1.42g/t Au from 149 m. The gold mineralisation here is associated with a strongly sulfidic (iron-rich) metasedimentary unit (26% sulfur). Likewise, the Athena project is a discrete gold target and the most northerly situated target along the Minigwal belt. This target was identified from a gold-silver-copper soil anomaly which occurs for over 1 000 m.

The area is underlain by greenstone (mafic rocks) that form a structurally controlled corridor flanked by granites. The northern section of the belt has not been tested by drilling, but two drill holes were completed by WMC Resources in the early 1990’s as part of a reconnaissance drill programme, which created two holes that straddle the belt, which the company did not test. St George has now completed two RC drill holes to provide more information on the complex stratigraphy of the belt and to test for mineralization that reflects the soil gold animalism.
