Burra Copper Mine Drilling, Cobar Region, NSW
- Core drilling program to commence at Burra and Block 51
The historic Burra Copper Mine is 40km east of Cobar and 5 km south of Canbelego and lies within GCR’s 100%-owned Burra Project.
Burra Copper Mine
The Burra Project has drill-indicated potential to host deep-seated, Cobar-style mineral systems with lenses, defined by drilling, containing copper and silver with minor gold and zones of lead-zinc-silver mineralisation.
A program of three core holes, from a six-hole proposal, has been approved by GCR’s board. Following government approval of GCR’s Surface Disturbance Notice, crews have been mobilised and drilling is expected to commence on Friday, 7th March.
New Burra Gravity Data
At the Burra Mine, mineralisation lies within a gravity high, apart from the shallow mineralisation in the northernmost drill hole. The mineralised zone is on the southern margin of a pronounced gravity low. Recent infill gravity surveying at 100m x 100m spacing (with 50m x 50m in-fill over the gravity low) has dramatically improved resolution of the anomaly. This anomalous feature has not been explained, is the subject of further evaluation, and will be tested in the current drilling program.
The gravity data is shown on the next page followed by plans and sections of existing and proposed drill holes at the Burra Mine and Block 51 Prospect. The drill program will be modified as it progresses.
