Just doing some more research into Specimen Reef.

Here's a good (but detailed) doc, best to do a search within the doc for "specimen" to find the important stuff. Basically it summarises previous exploration efforts on tenement EL11/2005 and mentions the gold grade that Nimrodel have previously referred to in historic exploration.

"Of the 15 diamond drill holes the only encouragement was the first hole, DDH SPC 1, which intersected
a narrow but very high grade zone, 0.2m @910g/t Au. Unfortunately, it was not until the last year of
tenure that Savage located the plans of the mine workings, which showed that most of the holes did not
test the reef.

Savage attempted to deepen several holes with limited success, so that ultimately only 3 holes
intersected the reef. Two of these probably missed the main shoot and, in the third, the reef interval was
not assayed. Based on this unsatisfactory drill program, and the old mine plans, Newnham in 1996
concluded that there is one, possibly two, narrow gold bearing structures, with no broader low grade
zones surrounding these.
In the Davis Creek Grid area to the north of Specimen Creek, Savage carried out geochemical soil
sampling, geological mapping and ground magnetic surveys. The magnetic data is noisy and complex
and the geochemical results are generally low order with some minor gold responses. In the same areas,
Savage also conducted stream sediment geochemical sampling. Near, but not at, the old Davis Creek
workings lead anomalies to 900ppm and zinc anomalies to 345 ppm were generated but were not
followed up by further work.
In 1996 Goldstream Mining NL/ Titan Resources NL commenced exploration. They commissioned
L Newnham to conduct a review of the Specimen Reef area (referred to above), and conducted a
detailed helicopter-borne magnetic survey. In 1997 they tested the Specimen Reef with two diamond
drill holes, intersecting 2m at 0.56g/t Au in one hole and only 0.05g/t from the reef position in the other
hole. Silicification and probably sericitisation are widespread in both holes, and a sheeted system of
siderite-quartz-minor pyrite veins cuts both altered and unaltered schist, but these carry no gold. In
1998-1999 detailed petrological studies were undertaken on the drill core.
The aero-magnetic data was interpreted, suggesting that the Specimen Reef is within a north east
trending structure which may extend for 2km in either direction and that the Specimen Reef system has
many similarities to Archaean and Proterozoic shear hosted deposits. The exploration target concept
was widened to include iron formation hosted gold deposits. A stream sediment geochemical survey
was completed but results were apparently compromised by widespread contamination caused by
historical mining."
