Pan Asia Metals has revealed more strong visual copper indicators from rock chips at its new flagship Rosario project in Chile after wrapping up its first fieldwork program that has backed up encouraging results thrown out from the site by previous explorers.
The company says its recent first-pass fieldwork programs included the collection of some 316 samples, including 193 soil samples, 100 rock-chip samples and 23 stream sediment samples.

It has reported many occurrences of secondary copper minerals, including malachite (green) and chrysocolla (blue) from various rock-chip samples, signalling significant potential for the red metal across all three of the project’s prospective trends. Initial observations of old workings also noted that some areas feature primary mineralised copper sulphides.

Management believes it has identified a myriad of “walk-up” drill targets across the project, with confirmation of the locations to come in the form of initial soil and stream sediment sample results. They are expected to be received within the next fortnight, while the rock chip results are anticipated in about a month.
Pan Asia Metals managing director Paul Lock said: “Initial field observations from the first phase of fieldwork provide compelling support for the work conducted by previous explorers. The program yielded many rock chip samples of green (malachite) and blue (chrysocolla) secondary copper minerals, as well as some copper sulphides, which is pleasing.”
Located 10km north of Codelco’s El Salvador copper mine, Rosario is nestled in the Chile’s central copper belt – one of the world’s most prolific copper-producing regions. Pan Asia says its early findings from old mine workings and outcrops in the project area suggest the presence of high-grade copper lodes and structural controls that present enticing early targets for the drill rig.
The company is also nearing the completion of its induced-polarisation (IP) geophysical survey, progressing some 19 IP geophysical survey lines for a substantial 27 line kilometres of survey that is expected to wrap up this week.
Management says it is hopeful the results from the IP survey will unveil some deep oxide zones that are potentially amenable to simple heap leaching mining operations. It believes the deep oxide zones will be pivotal in prioritising drill targets, with a view to launching a reverse-circulation (RC) drilling program next month.
