    Reef Gold

    I have a gold lease in the flinders ranges in south Australia and while dozing the top gypseous clay off to put through the dryblower came across a reef. this area was worked in the 1930's by dryshaking the top dirt. some shafts were sunk to a depth of 6-8 feet where pockets of gold were found.the gold appears to be elluvial with most pieces being rough and hackly. the larger nuggets I have found are crystalline.the reef is 4 feet wide with near vertical sides exposed to a depth of approx. 4 feet.the cap of the reef when broken off is a brecciated quartz and magnetite stone. the sides of the reef show a red and yellow clay out from the reef for about eighteen inches then turns to a dark green clay that when panned shows nodules of magnetite. so far have located two more reefs running parallel to the first one,each about 20-30 feet apart with dark green clay separating the reefs.this area differs from the rest of the lease as it appears to be a basin because the basalt type bedrock doesn't appear at the usual 4-6 feet. the lease is located on a diorite intrusion, could this be the source of the gold and are the reefs worth following along on the chance of finding pockets of gold.as it would be a costly exercise to have a geologist to have a look at the area was hoping you could give me some advice on what I should do. cheers Garry
