Cathedral
Rocks encompasses an area of historic base-metals production.
Elementos considers that the district is highly prospective
for Intrusive Related Gold systems. There has been no previous
exploration for gold or molybdenum.
Location and access
Cathedral Rocks, comprising a 128 km² lease,
is located 50 kilometres east of Armidale, northern NSW. The
Hillgrove gold and antinomy mine, which contains 6.25 million
tonnes at 4.3g/t gold and 1.6% antinomy, is located 25 kilometres
east of Cathedral Rocks.
Access is by paved roads and a network of farm tracks. Excellent
support infrastructure and local services are available in
Armidale.

Tenement acquisition agreement
In November 2009, Elementos has entered into an option
agreement with Kokong Holdings Pty Ltd and Brian Roach jointly
to acquire EL 7066. Pursuant to the option agreement, Elementos
is required to:
a) Reimburse Mr Roach’s prior exploration costs up
to $5,000;
b) Meet the minimum expenditure and reporting requirements;
c) Pay $2,500 within 7 days of execution of the agreement;
d) Pay $5,000 within 12 months of execution of the agreement;
e) Pay $15,000 within 24 months of the execution of the
agreement;
f) Rehabilitate any environmental disturbances caused during
exploration activities; and
g) Upon exercise of the option, purchase the tenement for
$150,000 cash.
Historical exploration
Cathedral Rocks is centred on the historic reef and
alluvial tin fields of Yaroona, Lauder and School Gully which
produced tin in the early 1900's. Whilst a number of gold
and base metal anomalies were identified in exploration during
the early 1950's, it wasn't until the 1970's that CRA Exploration
drilling intercepted a number of significant base metal mineralised
zones. Crucially, CRA Exploration did not analyse for gold
and molybdenum, now considered the most prospective targets
based on a new interpretation of the possibility of intrusion
related gold systems (IRGS) within the regional geology.
Mapping and sampling programs, targeting regions known for
gold, molybdenum, and tin mineralisation are well advanced.
Two anomalies have been identified from historical records
and are the focus of the current field campaign. Mapping has
identified lead, zinc and tin mineralisation in an alteration
related to dykes cutting the boundary of granites and their
host rocks.
A molybdenum anomaly has been identified from a review of
historical exploration data, which is considered significant
due to the strong association of gold with molybdenum in IRGS
systems. This prospect, located in the east of the Cathedral
Rocks tenement, has been reported to have a number of soil
samples with highly anomalous molybdenum values, but was historically
never analysed for gold. It is considered likely that the
area is prospective for gold, molybdenum, silver and tin.
Recent exploration activities
Mapping and sampling of this prospect is scheduled
to begin early in July 2010. Preliminary results have returned
geochemical signatures which appear to confirm Intrusive Related
Gold (IRG) style mineralisation in some parts of the property.
School Gully Creek
Mapping and sampling in the vicinity of the historic School
Gully tin workings have indicated the presence of IRG type
mineralisation with selective rock sample results returning
strongly anomalous gold, arsenic, bismuth and tin, with low
base-metals and low silver-gold ratios, which is common in
IRG gold system in northern New South Wales. Auriferous mineralisation
occurs in the contact zone of the Round Mountain granite and
its’ baked sedimentary wallrock. Selective rock-chip
sample results include 1.03g/t Au, 5.96g/t Ag and 1.82% As,
0.08g/t Au, 8.03g/t Ag and 0.21% As, 2.61g/t Ag, 0.3% Mo and
0.11% Cu; and 87g/t Ag, 0.12% Bi and >500g/t Sn .
From the 30 samples taken around the historic tin workings,
11 samples returned grades exceeding 0.8g/t Au, 5g/t Ag, 0.15%
As or 500g/t Sn.
Yaroonah
Base-metal mineralisation has been identified in dykes from
rock chip sampling at Yaroonah. Select rock chips returned
grades including:
- 4.87%Pb, 5.41%Zn and 188g/t Ag; and
- 3.15%Pb, 6.88%Zn and 51.1g/t Ag.
Yaroonah samples also contained up to 0.3% molybdenum and
189g/t silver from in selective samples. Even thought there
is very limited outcrop, from a total of 22 samples around
the old workings, 10 returned grades of over 0.5% lead, 0.5%
zinc or 10g/t silver.
(Au – gold, Ag – silver, Bi – Bismuth,
As – Arsenic, Sn – Tin, and Cu - Copper)
Prospectivity and exploration target
Intrusive Related Gold Systems are a style of mineralisation
where the minerals are deposited in halos in and around large
granitic intrusions characterised by suites of pale felsic
granites (Leucogranties). Gold, molybdenum, and tin deposits
are known to be related to intrusives. The Round Mountain
Adamellite is at the southern end of a chain of I-type leucogranites,
which hosts the Timbarra Gold Mine 200 kilometres north, as
well as the Kingsgate and Seven Hills deposits in between.
The Company is focusing on an area of hornfels (baked country
rock) that is suspended in the roof of the Round Mountain
Adamellite. Hornfels are a brittle rock that forms fractures
and open spaces easily when faulted, which can then be mineralised
by the fluids generated from the intrusion.
Drilling that has occurred has been in a localised area using
outdated exploration models. No exploration has been undertaken
for gold, or an intrusive related gold systems style deposit.
New understanding of intrusive related gold systems shows
that Cathedral Rocks has the required structure and lithologies,
indicative of excellent potential for large bulk tonnage mineralization,
which could be exploited by open cut mining methods. Intrusive
related gold systems are potentially economically significant
deposits.
Exploration strategy
On-going exploration will involve mapping and rock
chip sampling to extend and delineate the known zones of mineralisation
and identify new targets.
