Meeka Metals (ASX:MEK) said open pit mining activities at its Murchison gold project in Western Australia began ahead of schedule, according to a Friday Australian bourse filing.

Open pit support infrastructures were commissioned on site, including the administration complex and fuel storage facilities, with the heavy vehicle workshop nearing completion.

Expansion works on the carbon-in-leach gold processing plant continued to progress rapidly during February, the filing added.

The first ore is expected to be mined from the open pits in April and the process plant commissioning is expected to occur in June.

Its shares fell past 5% on market close on Friday.
