– Das aktuelle Bohrprogramm hat die Kontinuität einer hochgradigen
Goldmineralisierung innerhalb des Systems Alice Queen – One Mile
in bis zu 250 m Tiefe ab Oberflächenniveau bestätigt; das System
ist sowohl in der Tiefe als auch entlang des Streichens offen.
– Die Bohrergebnisse habe bestätigt, dass die hochgradige Goldmineralisierung eine moderate Mächtigkeit aufweist, mit Quarz-Sulfid-Adern assoziiert ist und in ausgeprägte, breite Alterierungsmäntel eingebettet ist (Serizit, Chlorit, Tonerde und Epidot).
– 3D-Modelle der Anomalie White Lion, die im Rahmen von Messflügen 15 km weiter südöstlich ermittelt wurde, haben eine 1,5 km breite, kreisförmige Donut-Struktur mit hohen Magnetfeldwerten skizziert. Die Magnetfeldquelle befindet sich in einer Tiefe zwischen 100 m und mehr als 500 m und fällt mit anomalen Werten in Gesteinssplittern an der Oberfläche (> 1,0 g/t Au) zusammen. Es handelt sich hier um ein außergewöhnliches Goldziel mit Bezug zu Intrusionsgestein, wie man es auch bei Mt Leyshon findet; das Goldziel wird im Rahmen der geplanten Folgebohrungen Anfang des Jahres 2018 genauer untersucht.
Spitfire Materials Limited (ASX: SPI) freut sich bekannt zu
geben, dass das Unternehmen mit seiner Explorationskampagne im Alice
River Joint Venture, 440 km nordöstlich von Cairns im Norden des
australischen Bundesstaates Queensland, einen fulminanten Start
hinlegen konnte; das erste Bohrprogramm, das mit dem RC-Verfahren
(Umkehrspülung) absolviert wurde, hat großartige Ergebnisse erzielt.
Die ersten Bohrungen, die auf das bereits angekündigte
Explorationsziel in den Prospektionsgebieten Alice Queen und One
Mile gerichtet waren, haben ergeben, dass sich sowohl unterhalb als
auch in Streichrichtung historischer Goldbergbaubereiche eine
bedeutende, hochgradige Primärgoldmineralisierung befindet.
Das im Oktober 2017 bei Alice River durchgeführte Bohrprogramm
bestand aus 14 Löchern und umfasste 2.397 Bohrmeter; die in den
1980er und 1990er Jahren von früheren Betreibern absolvierten RC-
und Diamantbohrungen konnten erfolgreich validiert werden. Die neuen
Bohrergebnisse haben gezeigt, dass sich das Goldsystem weiter
ausdehnt als bisher angenommen und sowohl entlang des Streichens als
auch in der Tiefe offen ist. Die Bohrungen bei One Mile zielten auf
die im Fallwinkel abwärts driftenden (nördlichen) Ausläufer einer
Mineralisierung in geringerer Tiefe bei Alice Queen ab.
John Young, Geschäftsführer von Spitfire, erklärte, dass die
erste Bohrphase das große Potenzial des Projekts Alice River
bestätigt hat, welches sich neben dem wachsenden Portfolio an
Goldprojekten in der Region Kalgoorlie in Westaustralien zu einem
bedeutenden längerfristigen Explorationsprojekt entwickeln dürfte.
Wir haben einen fulminanten Start hingelegt; mit unserem ersten
Bohrprogramm konnten wir beeindruckende Ergebnisse erzielen, die
unser Geomodell bestätigen und uns bessere Einblicke in die
Geometrie und Kontrollstrukturen der Mineralisierung bei Alice River
Anhand unserer bisherigen Arbeiten konnten wir eindeutig ein
bedeutendes hochgradiges Golderzgangsystem in den Bereichen Alice
Queen und One Mile ermitteln, das beste Chancen hat, weiter zu
wachsen und wo schon in naher Zukunft Ressourcen erschlossen werden
Gleichzeitig haben wir auf dem gesamten Projektgelände eine Reihe
von Zielen ermittelt, darunter auch ein 15 km südöstlich gelegenes
vielversprechendes Goldziel mit Bezug zu Intrusionsgestein, das
starke Ähnlichkeit mit der Lagerstätte Mt Leyshon (3,5 Millionen
Unzen) aufweist. Dieses und andere Ziele werden im Rahmen eines
detaillierteren Explorationsprogramms bei Alice River im Jahr 2018

ALICE QUEEN – ONE MILE MINING CENTRE
The historical Alice Queen Mine and One Mile prospect areas, are
located on granted Mining Leases ML2901 and ML3010 respectively (see
Figure 1 – Alice River Drill Plan).
As part of the planned program, holes 17AARC001 to 17AARC014 were
drilled to test the mineralization below the Alice Queen pit and to
follow the mineralized zone to the NNW, down-plunge of the Alice
Queen Pit, towards One Mile.
Significant RC drilling intercepts >0.5g/t are listed below with
full results provided in Table 2.

Reverse Circulation holes 17ARRC001 to 17ARRC003, and holes
17ARRC012 – 17AARC014 were completed over the One Mile Prospect,
targeting extensions of the higher-level vein system at the Alice
Queen pit both along-strike and down-plunge. Drilling was successful
in defining broad alteration zones with low to moderate grade gold
mineralisation over significant widths below 100m. The results from
17ARRC002 are very encouraging, with this hole identifying the
likely extension of the main quartz vein/lode in the Alice Queen pit

FUTURE DRILLING PLANS
Given the impressive initial results from Alice Queen and One
Mile, which has confirmed the presence of a significant mineralised
system, Spitfire intends to commence follow-up drilling in 2018 to
evaluate extensions of the system at depth and along strike.
Initial drilling will also be undertaken at numerous other gold prospects along strike, such as Julie Ann, Peninsula King, Big Blow and German Jack. These historical gold prospects are located to the south-east of Alice Queen and One Mile along the Alice River Shear Zone.
Historical drilling at these prospects has yielded high-grade gold intercepts but has only tested the mineralisation to a relatively shallow average depth of just 40m. The Company believes that it has an exceptional opportunity to drill below these known systems in 2018, and build up a portfolio of gold resources along the highly prospective Alice River shear zone.
The White Lion Prospect lies some 15km along strike to the south-east of Alice Queen area, located on EPM 26266. Several rock chip samples were taken by Spitfire at this prospect over a quartz-vein breccia zone located just north of the White Lion magnetic anomaly. The brecciated vein zone outcrops for approximately 300m and trends north-west, sub-parallel to the regional shear zone (see Figure 4 – White Lion Prospect and rock chip results).
Eight rock chip samples were taken by Spitfire from surface outcrops, and results returned assays of up to 1.7g/t Au. These results have verified the anomalous rock chip results reported from historical exploration work carried out in the 1980s, which returned assays of up to 2.56g/t Au.
Shallow Airtrack drilling carried out in the 1980s also returned anomalous gold, with the best interval returning 20m @ 0.4 g/t Au within hole ARAT-244. The historical Airtrack drilling only reached depths of 30m, and the gold zones defined were never followed up with further exploration or deeper drilling. There is very little exposed outcrop in the area, however altered granite was noted as well as a fine-grained porphyry unit (mapped as green aplite dyke), very similar to what has been mapped on the periphery of the Alice Queen pit.

Figure 4: White Lion Prospect and rock chip results GEOPHYSICS
A detailed aeromagnetic survey was flown by Spitfire in mid-2017
over the most prospective portions of the Alice River Gold Project
tenements. 3D magnetic inversion modelling of the White Lion
magnetic feature was completed in late September. The donut-shaped
anomaly has a low amplitude signature (50nT) and is around 1.5km in
diameter. The inversion model suggests that the magnetic source has
the form of a sub-vertical cylinder, with a depth to the top of
around 100m. The donut feature becomes more magnetic below 500m
depth, (See Figures 5 and 6).
The pipe-like magnetic anomaly is reminiscent of classic porphyry
copper-gold signatures, but is somewhat lower in amplitude. However,
the anomaly could be associated with an intrusive-related gold
system, as there are anomalous gold geochemical results around the
White Lion area (historical rock chips, soils, air track holes, new
rock chips). Along the north-eastern side of the donut magnetic
feature, a strong regional north-west trending fault structure is
also evident in the magnetic data, which is likely be an important
structural feature related to gold deposition.
The target at White Lion could be more clearly defined by
employing ground electrical geophysical surveys such as Induced
Polarisation, which has been recommended by the Companys
The magnetic feature is similar in size to the Mt Leyshon breccia pipe. The Mt Leyshon pipe has a remnant low magnetic anomaly of around 2000nT related to the intrusion and biotite-magnetite alteration. Pervasive phyllic alteration can also destroy magnetite, resulting in lower amplitude anomalies. The Mount Leyshon gold deposit, which lies to the south-east, is estimated to contain some 3.5 million ounces of gold. Further exploration work at White Lion is planned for 2018.

The shear zones are largely hosted within the Imooya Granite, a pale grey to white mica-biotite leucogranite (commonly referred in the old reports as an adamellite), of the Siluro-Devonian Kintore Supersuite. At the north end of the project the shears intersect gneisses and schists of the Sugarbag Creek Quartzite, which forms the lower part of the Mesoproterozoic Holroyd Met amorphics.
– The gold-bearing shear zones extend episodically for approximately 50 km strike length. The gold mineralisation is generally hosted in quartz veins, and minor quartz
breccias, up to 10-15 m wide in places. Gold mineralisation is
focused in linear pods up to
150 m strike length.
– Gold often occurs as both fine free-gold in quartz or
interstitial within arsenopyrite and stibnite. Green-white
quartz-sericite-epidote alteration zones extend 50-70 m around the
mineralised veins some deposits but generally the quartz veins
display narrow alteration selvages. The weathered (oxide) zones at
10 to 20 m deep.
– Minor pyrite and other fine-grained sulphides (e.g. arsenopyrite, stibnite) are present
as narrow bands in laminated quartz veins and disseminated with
the quartz breccias. The NW-trending quartz veins are sub-vertical
to steeply dipping (approximately 80 degrees to the southwest in
places). There are other sub-parallel quartz veins, some of which
mineralized, while some are barren.
– The gold mineralising fluids probably focused into dilatational
structural zones (e.g. fault jogs, cross faults and shears) within
the adamellite, forming zones of stockwork veins and also
mineralised breccias. – Three gold genetic models are considered -
