VANCOUVER, BC, Oct. 7, 2021 /CNW/ - Leviathan Gold Ltd.
("Leviathan", the "Company") (TSXV: LVX)
(Germany: 0GP) is pleased to
announce that it has commenced drilling at the historic Leviathan
Mine within the Company's Timor property. This initial phase of
work, which is expected to comprise at least 3,000 meters of
diamond drilling, has been designed to target strike and depth
projections of known high-grade gold mineralization in underground
mine workings understood to have been abandoned in 1905. Recorded
historic production for the Leviathan Mine - itself an amalgam of
closely adjacent shafts and underground workings - is 181,000
tonnes for 67,511 ounces of gold at a grade of 11.4 g/t
Au1.
Compilation and review of historic mining records and plans
together with modern field work by Leviathan's geological team
suggests that gold mineralization at the historic Leviathan Mine is
open along strike and at depth - presenting clear drill targets
immediately beneath abandoned mine workings, including areas
underground development drives that were never fully exploited.
These targets occur from depths as shallow as ~70 meters.
Mineralization at the Leviathan Mine is known to occur as quartz
veins, stockworks and spurs within a broad north-south trending
fault system, itself comprising numerous individual faults. Where
mineralized, these are locally termed "reefs". By 1862
approximately 90 such reefs were reportedly known in the area of
Leviathan Mine, with production records suggesting that such
occurrences produced "more than an ounce of gold per
tonne" 2.
Writing in 1913 - subsequent to the closure of the Leviathan
Mine - the Geological Survey of Victoria3 observed:
"From the surface to 240 feet the Old Leviathan averaged for
a long time 1 oz. per ton and the ore was 10 feet to 20 feet wide.
At no point lower than 300 feet has this line been
worked" and "The 960-ft level, the next level at which
the Old Leviathan Reef formation was cut, shows a splendid quartz
reef with encouraging prospects, and going strongly underfoot
south", and
"The New Reef in in the 960-ft level warrants further
exploiting and this should be done if ever the mine is again
worked".
Within the area contemplated by current drilling, repeated
parallel to sub-parallel reef targets extend over an area of at
least 130 meters laterally and in excess of 750 meters of strike.
Preliminary indications are that this fault system persists for
several kilometers to the north of the current target, and that
parallel systems appear to exist to both its east and its west.
These occurrences will be reported on in due course.
Hard rock gold mineralization in the area of Leviathan Mine
furthermore appears to have been a significant source for the rich
alluvial gold deposits that extend for kilometers downstream of the
Leviathan Mine in an area known as the Chinaman's Flat Lead ("the
Lead") - the scene of a major gold rush in the 1850's. At this time
some 30,000 diggers were reportedly engaged in mining on the Lead,
with reports4 suggesting an average yield for the Lead
of "four ounces gold to the load" (or approximately 163
grams of gold per cubic metre) and that grades in many shafts (in
the alluvial material) ranged from 2 kilograms to 5 kilograms gold
per cubic metre5.
Leviathan's current drill targets and provisional drill
locations are shown in Figures 1 and 2, oblique underground target
projections in Figures 3 and 4, and site photographs illustrating
the surface expression of the Leviathan reefs in Figures 5 and 6.
It is understood that historic operation of the Leviathan Mine
ceased due to the inability of the mining, metallurgical and
pumping techniques of the day to perform economically at the
required depths.
Leviathan Gold Chief Executive Officer, Luke Norman, remarked: "We are very excited
to be commencing drilling works at the old Leviathan Mine, our
namesake target. Since completing the spin-out our technical and
permitting team has been working diligently to gain the necessary
permits and access to drill these exciting targets. Compilation and
review of historic records by Leviathan's geological team, in
conjunction with new fieldwork suggest that historic mining ceased
at relatively shallow levels, leaving multiple, stacked high grade
ore-shoots open to depth and along strike. Our plan is to
systematically test these features via modern drilling and assaying
techniques, confirming their grades and widths, while at the same
time continuing to assemble targeting information on what appear to
be further reef occurrences parallel to and along strike from the
Leviathan Mine".
About Avoca and Timor
The Victorian goldfields are one of the world's major gold
provinces, with recorded historic production in excess of 2,500
tonnes - or over 80 million ounces – of gold since their discovery
in 18516. The Avoca and Timor projects comprise 223
square kilometers of exploration tenements within these goldfields,
approximately 180 kilometers north west of the state capital of
Melbourne. The Projects are
well-served by modern infrastructure, are easily accessible via
paved roads, and fall less than 100 kilometers from the regional
cities of Bendigo and Ballarat, both long-established centers of
mining services and expertise.
The Projects are located within an area of the Victorian
goldfields, the golden triangle, that is home to large scale gold
deposits with long and very prominent histories of production such
as those at Ballarat, Bendigo and Castlemaine. More recently, major
discoveries have also been made at the Fosterville Gold Mine near
Bendigo (operated by Kirkland Lake
Gold, recently merged with Agnico Eagle Mines Ltd.), which
boasts reserves of 1.70 million ounces at an average grade of 23.1
g/t Au, including 1.16 million ounces at an average grade of 61.2
g/t Au7. Within the area being explored by Leviathan
Gold hundreds of small historical gold mines are known to have
existed within a 50 km radius of Avoca and Timor.
The Avoca and Timor projects were the subject of historical
mining between the 1850's and the early 1900's, during which era
operations targeted so-called alluvial and "deep lead" gold
occurrences – buried secondary auriferous river-bed deposits - as
well as primary vein-hosted mineralization developed via shaft and
underground stoping methods. Such operations reportedly produced
some 1.3 million ounces of gold in the Avoca and Timor project
areas alone, the majority of this arising from alluvial and "deep
lead" mining - a function of the richness of the alluvial
mineralization around Maryborough, so great that it eclipsed the
importance of reef mining. As such little capital was available for
deep hard rock development3. The mining, water removal
and ore processing methods of the day were rudimentary, such that
only isolated extraction of shallow, near-surface, visible,
high-grade mineralization was possible, resulting in only very
selective and discontinuous mining. Over fifty such gold
occurrences are known within the Projects, and despite this
prodigious endowment, no systematic exploration of the Projects has
occurred. With only limited exploration work having been recorded
since WW1, numerous targets to test, and mineralization potentially
open to depth at most of these, a rare opportunity exists for
Leviathan to pursue a consolidated approach in the exploration of
near-surface mineralization using modern drilling, geochemical and
geophysical techniques.
Historical records are not historical resource estimates, but
instead are official Government records of gold production from
individual mines. Historical production records do not carry a
comparable confidence level to a current Mineral Resource estimate
reported in accordance with CIM standards for resource estimation
and should not be treated as such. Leviathan does not treat
historical production records as indicators of a current mineral
resource or mineral reserve. The information relating to historical
gold mines has not been independently verified by the Qualified
Person and such information is not necessarily indicative of
mineralisation on the properties that it the subject of this Press
Release.
Comparable Projects
Leviathan considers the Currighanalt project, in Northern Ireland, to be potentially similar in
terms of its geology to the Avoca and Timor projects. In 2018
Dalradian Resources Inc. defined Measured and Indicated Mineral
Resources of 6.34 million tonnes at a grade of 15.01 g/t Au for
3.06 million ounces of gold, and Inferred Mineral Resources of 7.72
million tonnes at a grade of 12.24 g/t Au for 3.04 million ounces
of gold8. The Currighanalt project, which is
described as "a high grade orogenic gold deposit characterized
by a series of west-northwest trending, moderately to steeply
dipping, stacked quartz-carbonate-sulphide veins and arrays of
narrow and short extension veinlets" is hosted by rocks of
similar lithology and age to those found at Avoca and Timor.
Future Work Programs
There are over thirty historical gold workings within the Avoca
project area9, all of which require additional mapping,
surface sampling and drill testing to assess their potential and on
which the Company intends to report on an ongoing basis. The
highest priority targets include:
- Pyrenees Reefs: 16,199 tons mined for 16,602 ounces of gold to
a depth of 130 meters at an average recovered grade of 32 g/t Au,
worked from 1860 to 1912; mineralized shoots per historic
underground mine plans.
- Excelsior Reef: 13,200 tons mined for 9,260 ounces of gold to a
depth of 100 meters at an average recovered grade of 22 g/t Au,
worked from 1909 to 1915; mineralized shoots per historic
underground mine plans.
- Vale's Reefs: 1,444 tons mined for 1,388 ounces of gold to a
depth of 52 meters at an average recovered grade of 29.4 g/t Au,
worked from 1865 to 1883.
- Monte Christo Reefs: 2,795 tons mined for 937 ounces of gold to
a depth of 30 meters at an average recovered grade of 10.3 g/t Au,
worked from 1872 to 1877.
The Timor project lies immediately east of the Avoca project and
hosts numerous hardrock and alluvial gold deposits as evidenced by
the extent of historic workings, of which approximately twenty
hardrock workings can be considered to have been significant
producers. The highest priority targets include:
- Shaw's Reef: 16,881 tons mined for 12,623 ounces of gold to a
depth 130 meters at an average recovered grade of 22.9 g/t Au,
worked from 1883 to 1891. Along strike of this fault zone,
arsenopyrite and stibnite mineralization is recorded in association
with the gold mineralization indicating possible epizonal
Fosterville-style gold mineralization.
The Leviathan Group of Mines and Shaw's Reef both lie on
separate large regional north-south structures known to occur for
tens of kilometers associated with hardrock workings over their
length. Neither of these structures have witnessed significant
drilling. These two mineralized structures will be a near-term
focus for exploration within the Projects. Modern core orientation
techniques which help with understanding the structural controls on
mineralization, will be systematically applied during this
program.
