DRILLING COMMENCES ON NICKEL SULPHIDE TARGETS
Highlights
-
~1,500m RC program to test strong bedrock conductor at Oaktree North, along strike from early magmatic nickel sulphides previously intersected at Oaktree South
-
Four additional targets to be drilled, including one with previously intersected nickel sulphides (Target ZV07)
-
‘Fertile’ environment confirmed for discovery of Ni-Cu sulphide mineralisation: right mafic-ultramafic rocks and right sulphides
-
Regional MLTEM program targeting deeper conductors in the “Oaktree Structural Corridor” has also commenced
-
Additional 3,000m of aircore drilling also commenced to test multi-metal surface anomaly at Widowmaker, and calcrete surface gold anomalies at Zanthus

Summary
==> picture [228 x 71] intentionally omitted <==
Buxton Resources Limited (ASX: BUX & BUXO) has commenced a ~1,500m RC drill program at the Company’s 100% owned, highly prospective Zanthus Ni-Cu Project, located 60km along strike from Sirius Resources’ Nova-Bollinger Ni-Cu discovery in the Fraser Range Nickel province, Western Australia.
The program will primarily target the newly defined strong MLTEM conductor at Oaktree North (Figure 1, Table 1), at least four additional untested targets previously generated will also be drilled (Figure 2, Table 1).
Table 1 Drill targets and brief descriptions at the 100% owned Zanthus Ni-Cu Project
| Name | Priority | Easting | Northing | Description |
|---|---|---|---|---|
| Oaktree North |
1 | 576530 | 6530550 | Newly defined strong bedrock MLTEM anomaly to the north of Oaktree South (described below). The recent MLTEM survey defined a more highly conductive target which could represent semi-massive or massive Ni-Cu sulphides. |
| Oaktree South (previously ZV10) |
1 | 576610 | 6530150 | Abundant, definitively magmatic, sulphide blebs of intergrown pyrrhotite, crystalline pentlandite and some chalcopyrite identified within ultramafic rock (Hole ZRC086). Additional drill testingwarranted to further test this MLTEM conductor. |
| ZV07 | 1 | 574200 | 6527150 | Hole ZRC088 intersected ultramafic rock with minor pyrrhotite and traces of nickel sulphide minerals. Moderate to high strength conductor, irregular shape, wedged between two broadgravityhighs requires additional testing. |
| ZV03 | 2 | 576430 | 6524400 | Hole ZRC074 was abandoned due to sand cover and did not reach target depth or explain the anomaly. Weak, small, sub- horizontal conductor within or above interpreted intrusive body. |
| ZV19 | 3 | 573580 | 6531150 | Weak,steeplyeast dippingconductor. Requires drill testing. |
| ZV15 | 3 | 575890 | 6524650 | Weak, small, sub-horizontal conductor within or above interpreted intrusive body. Requires drill testing. |
Oaktree North & South
In 2013 a moderately conductive large depth extent conductor (ZV10) was modelled from a single MLTEM line. Drill hole ZRC086 tested this target and intersected ultramafic rock with abundant magmatic blebs of composite pyrrhotite, pentlandite and chalcopyrite.
The occurrence of these definitively magmatic nickel sulphides is indicative of sulphide saturation occurring at an early magmatic stage, before substantial amounts of nickel sequestering silicates (olivine, pyroxenes) were able to crystallize. As such, the confirmed presence of these magmatic nickel-copper sulphides indicates excellent prospectivity for larger, potentially economic, accumulations of nickel-copper sulphide mineralisation.
This encouraging drill intersection in ZRC086 was followed up with a 13.6 line km MLTEM program in early July, 2014. Results of the combined 2013 and 2014 MLTEM surveys show a moderately conductive zone centred on line 6530150mN, where it was drill tested with ZRC086 (Figures 1 & 2). However, the new MLTEM data has detected a highly conductive target to the north of the original Oaktree target which may represent semi-massive or massive Ni-Cu sulphides.

Conclusion
==> picture [228 x 71] intentionally omitted <==
The previous drilling, geophysical and geochemical surveys at Zanthus show a very large, ultramafic-mafic system that is “live” and highly prospective for economic nickel-copper sulphide mineralisation. Important features of this system include;
-
Located in Proterozoic orogen in close proximity to major, crustal scale shear zone and broadly along strike from world class Nova-Bollinger discovery;
-
Very large ultramafic-mafic system with significant geological complexity and numerous smaller dyke and/or sill-like bodies;
-
Sulphur-rich country rocks to potentially contribute to sulphur saturation of ultramaficmafic rocks; and
-
Ultramafic rock with petrographically verified, abundant magmatic blebs of composite pyrrhotite, pentlandite and chalcopyrite.
