    Hi Seven's, I can concur with what '56 says regarding potential at La Jacinta..

    If you want maps, historical data etc then feel free to ping us at [email protected]

    Would normally have it on hand but have swapped laptops and admit my focus has been anywhere but on the share market for the last 6m or more..

    In the meantime this is a fairly accurate description, underpinned by official docs/reports etc.

    Note the gold price assumption used in the FS $1200 usd/oz. So a nic little uplift can be expected on gold price alone & there is 1.2m/oz on the books in the indicated category!
