Frontier Resources Ltd is pleased to announce an update on exploration activities at its Andewa gold – copper project (EL 1345) in West New Britain Province of Papua New Guinea (Figure 1). Exploration activities re-commenced at Andewa in early February, 2011, with the establishment of a camp to support the programs (Figure 2). A grid controlled soil sampling program in 2010 was very successful and delineated extensive gold (Figure 3) and polymetallic anomalies. Results from the concurrent 3D induced polarisation (IP) survey showed several very large areas of coincident deep seated and near surface chargeability, resistivity and conductivity anomalies (Figure 4). The geochemical and geophysical data sets were used to design the next phase of exploration including targeting hand trenching (Figures 4, 6a/b and 8), infill soil sampling (Figure 5) and more geological / structural mapping and creek sampling. 932m of hand trenching and more than 18 linear kilometres of soil sampling have been completed in 2011 and the programs are continuing. The 10,000m drilling program is now scheduled to commence mid June, subject to barge mobilisation (Figures 7 and 9). The program has been delayed due to customs clearance of required drill rods and consumables. Frontier owns and operates its own drilling and earthmoving equipment to minimise costs and maximise exploration output. An excellent value new and used capital equipment purchasing program has been completed to ultimately allow the drilling program to proceed as planned and ultimately with ground support. Four additional diamond drilling rigs are under construction and are expected to be completed and delivered to PNG by early September. Frontier will have the capability to drill to a maximum of about 1,700m depth, (if warranted) with the track mounted CS1800 (Figure 10), to 1,100m with the track mounted but also heli-flyable CS1300 and to 400m with our other small rigs. Earth moving and support equipment capacity has been significantly enhanced to cater to the logistics of the program.
DETAILS
The hand trenches were designed to test interpreted coincident sub surface conductivity and chargeability anomalies demonstrated by the 3D-IP, plus outcropping gold and other base metal mineralisation defined by the soil sampling program. Six trenches have been cleared to a minimum depth of 1.5m and 409 continuous chip channel samples were collected for 932m total. The nominal sampling interval is 3m reducing to 1m in more intensely mineralised sections of the trench.
Six infill soil lines were completed (714 samples) between existing anomalous gold and polymetallic soil geochemistry on a 25 m downline interval, for 18,175 line metres.
Structural mapping and rock chip sampling has continued on some of the creeks not covered in last year’s program. This program involved selective sampling of structures and mineralised horizons to determine possible structural controls on the mineralisation at Andewa.
Recent excavations of a contour trail around the small hill containing a gold-copper -molybdenum soil anomaly on line 12400E show areas of abundant quartz –limonite –sulphide (dominantly pyrite with trace chalcopyrite) stockworking within argillised intrusives (Figure 6a,b). The veins are either steeply dipping or flat lying.
Soil line 9800E runs through a hill consisting of strongly silicified and oxidised reddish brown, approximately east -west trending hematitic hydrothermal breccia. Silicified and argillised angular rock fragments are found within a clast-supported matrix with open spaces and cavities. It is located at the far eastern end of the Komsen Prospect.
A drill pad has been prepared (Figure 9 - the hole will be drilling to left) to test the geological, gold in soil, chargeability and conductivity anomalies on this line (refer to Figure 7).

The economically significant areas however are greater than 0.05 g/t gold (50 ppb) and particularly greater than 0.10 g/t gold (100ppb). There is locally good correlation between higher tenor soil assays and specific geomorphic situations.

Die Bohrungen wurden Ende July begonnen und Ende September werden die Ergebnisse erwartet. Hier werden insgesamt 10.000 Meter mit Diamant-Gerät gebohrt. Das erste Bohrloch wurde am 28. Juli fertiggestellt. Es dürfte also spannend werden.
Hier noch ein paar (frühere) Kommentare von "Hotcopper":
"Having a look at the most recent IP images from Andewa two things interest me: size (volume) and shape...Even with conservitve figures, IF these IP zones do represent suplhides (highly likely induced polorisation is based on sound science) and IF the areas do grade the size of this deposit could be imense. 7km2 of what is likely sulphide mineralisation, say 1/4 is mineralised to a depth of ??? with a density of 2 tonnes per cubic metre?? Anyone done any conservative mathematics? A few decent intercepts with the drill rig and this could be a real winner with one 100% owned project of their own...All of the this however needs to proven with the drill and its assays. But I think this could be very exciting to own for a year or two. Keep holding long term holders the stock still seems pretty tightly held".
"I recently posted that Andewa was potentially very similar to "Lihir" and am now very happy to see an experienced professional who has worked on "Lihir" doing so also".
"I'm a Geo and am very excited ( I cant swear on here but im swearing in my own mind) about these results. Figures reported here are in g/t and align with an increadible IP anomaly. Im used to getting excited about ppm. Western mining had a saying about the three G's before drilling. You had to have all three".
Noch kurz zur Info: Bei "Lihir" handelt es sich um eine 45 Millionen Unzen Mine!
Innerhalb einer Woche nun 50% nach oben gelaufen und in D bisher noch nicht wirklich bekannt.
Danke noch für den Tipp, Rheumax. Hätte meine Käufe nicht besser timen können.
:-))

Die großen Bohrergebnisse kommen noch...

Dabei sind Bonanza-Grades bei dieser Art von Lagerstätte nicht zu erwarten. Wird aber durch die üppige Tonnage ausgeglichen. Ähnliche geologische Situation wie bei Intrepid.
Aber die Erwartungen waren offensichtlich sehr hoch.
Interessant: Die Einladung an die Aktionäre zum Besuch der Liegenschaft auf Kosten von Frontier.. Aber denke mal, dass die Anreise aus Deutschland nicht mit übernommen wird.. :-)
