Laconia Resources (ASX: LCR) has the potential to extract commercial ore from the Lennons Find Base and Precious Metals Project using a two stage process, initial metallurgical test work has found.
Sulphuric Acid leach was found to recover 75% of the copper and 87% of the zinc from ore, while subsequent cyanide leach testing recovered 87% of the gold and 94% of the silver.
Further metallurgical test work will focus on column leach testing at coarser crush sizes, in order to replicate the conditions expected in a small scale, low capital cost heap leach operation.
The Lennons Find Project recently doubled the total JORC Resource at Lennons Find to 1.85 million tonnes at 82 grams per tonne (g/t) silver, 0.26g/t gold, 0.2% copper, 1.4% lead and 5.1% zinc.
Further drilling planned
Lennons Find, located in the eastern Pilbara region of Western Australia, comprises the Hammerhead deposit along with four other mineralised prospects; Bronze Whaler, Tiger, Mako and Grey Nurse.
Further drilling is planned to look for additional resources at depth at the Hammerhead deposit and target further oxide resources in the project area.
Reverse circulation drilling will be carried out at the mineralised prospects seeking a potential shallow supergene enrichment zone.
Laconia also plans to investigate outcropping gossans and soil anomalism at Lennons Find.
Peruvian project acquisition goes ahead
Earlier this month, Laconia resolved to proceed with the acquisition of the Rasuhuilca advanced high grade gold silver development project from Gold Mines of Peru, after completing due diligence on the project.
Rasahuilca has near term development potential and major exploration upside, and is located in mining friendly Peru.
This acquisition will establish Laconia as an emerging precious and base metals exploration and development company and diversifies its activities from the company's existing portfolio of projects in Western Australia.
Laconia plans to update and reaffirm a Feasibility Study carried out in June 2008, with the aim of bringing the project into production in 12 to 18 months.
