If only one could travel back in time - to collect specimens or visit
places in hindsight! The following extracts, taken from separate
publications, give you some idea of the mineral riches that previously
existed. They both concern the same locality - the "Garibaldi Gold Mine"
or "Garibaldi Crystal Mine" as it is also sometimes known. The mine was
situated near to the now deserted gold-mining towns of Solferino and
Lionsville. This site is not far from the present day town of Tabulam, in
North-Eastern New South Wales, in Eastern Australia.
Rich alluvial diggings gave way to deep mining on the field, as the miners
followed the gold-bearing reefs underground. In c.1912, when diggers were
trying to sink a shaft to cut the Garibaldi reef, the ground sounded
hollow when struck with their picks. It was decided to put in a shot of
explosives. When the dust had cleared, they saw that they had broken into
a fairyland - a crystal cave lined with calcite crystal. Tourists came
from as far as Grafton to gaze on this spectacle. It must have still been
a sight years later, in the early 1920's, when George Smith, Inspector of
Mines for NSW wrote this report for the NSW Department of Mines:
"A very interesting occurrence of this mineral (calcite) may be seen
in a large vugh in the Garibaldi Mine (Lionsville). It was
interesected obliquely at one end by a tunnel... As exposed, its
largest dimensions are 70 ft. by 16 ft. and 9 ft. high. It is lined
with crystals of calcite of all sizes up to 2 ft. or more in
diameter, some are cloudy, but most are transparent of light sherry
colour, or colourless, and fine examples may be obtained of the
variety which shows double refraction clearly and is known as
Iceland Spar. Further exploration might show that the cavern extends
beyond its known limits, but nothing has been done to enlarge it,
and it remains as when first discovered. Though many of the crystals
have been broken and removed, there yet remain so many intact that
the damage is hardly noticeable...... Liquid inclusions from small
to large bubbles as much as 2 inches long were seen containing
possibly a desert-spoon full of the liquid..... upon some of the
large crystals, short stout, hexagonal prisms of secondary calcite
have been deposited. As single crystals and groups they are attached
to the polished surfaces of the large crystals, and a very slight
jar will detach them from their smooth base."
It was not to be for long, as a passage from the book Forgotten Country -
The story of the Upper Clarence Gold Fields, by Isabel Wilkinson records.
"There arrived in Lionsville c. 1924, a German, Dr. Stroebal, and
soon a new sensation stirred the district. The crystal was to be
sent to Germany for the manufacture of "high quality lenses".
Machinery was brought and set up to extract the crystal and a case
mill, powered by an early model Fordson tractor to cut timber for
packing the precious glass-like blocks.... Many of the locals had
jobs in the new industry - taking out the blocks of crystal; cutting
timber for the mill, making the cases for packing; carting the
finished crates of crystal to Grafton for loading on to
boats......Dr Stroebal gave instructions... none were to be broken,
and as each piece came out, a crate must be tailored to fit
it.....It has been said that Dr Stroebal travelled to Grafton each
time a consignment went out and personally saw it shippedsafely away
to Germany...."
What a shame! Imagine the tourist drawcard that such a place would make
today! It is ironic that this "Iceland Spar" calcite was probably sought
for rangefinder devices that eventually were to be used as weapons of war
in the coming decade.
