New geophysical surveys (IP) at Mt FisherMt Eureka Project identify numerous highpriority Gold targets
-
Mt Fisher greenstone belt is one of the most remote and least explored greenstone belts within the gold-prolific Yilgarn Craton
-
Past drill intercepts at Mt Fisher of 9m @ 34.34 g/t Au demonstrate the high-grade potential of the belt
-
Currently, limited drilling in the Mt Fisher - Mt Eureka corridor has delineated a gold Mineral Resource of 187koz Au within 100km of Strickland Metals’ Milrose Project, which was recently acquired by Northern Star for approximately A$61m.
-
Rox holds a dominant tenure position over the Mt Fisher-Mt Eureka belt and has recently conducted a Gradient Array Induced Polarisation (GAIP) survey over the project area
-
The geophysical surveys have identified multiple walk-up drill targets, located along strike from known gold mineralised trends that are characterised by high-sulphide content (consistent with the causative geology of GAIP anomalies).
-
Rox is progressing opportunities to advance and monetise the highly-prospective Mt Fisher - Mt Eureka Project, given the Company’s priority focus on developing its flagship highgrade Youanmi Gold Project in WA

West Australian gold exploration and development company Rox Resources Limited (“Rox” or “the Company”) ( ASX: RXL ) , is pleased to report results from recently completed geophysical Gradient Array Induced Polarisation (GAIP) surveys at its Mt Fisher and Mt Eureka Projects in Western Australia.
The 100% Rox Resources owned Mt Fisher Gold Project and the 51% gold rights (rights to earn uo to 75%) Mt Eureka Gold Project are located in the Northern Goldfields, with a gold Mineral Resource of 187koz Au defined within a 1,150km[2 ] tenement package that is highly prospective for gold and nickel mineralisation.

Managing Director Comments
Rox Resources’ Managing Director, Mr Robert Ryan, said:
“The geophysical surveys conducted recently at Mt Fisher and Mt Eureka have highlighted a number of walkup drill targets. The surveys have detected potential sulphide-bearing structures, which could host gold mineralisation as seen elsewhere in the tenement package.
“The 1,150km[2 ] tenement package represents a district-scale exploration opportunity for both gold and nickel sulphides, that Rox will continue to advance in order to generate value for our shareholders.”
The 100% Rox Resources owned Mt Fisher Gold Project and the 51% gold rights (rights to earn uo to 75%) Mt Eureka Gold Project are both located in the Northern Goldfields, approximately 500km north of Kalgoorlie (120km east of Wiluna) (Figure 1).
The Projects are at an advanced exploration stage with an existing gold Mineral Resource of 187koz Au defined at Mt Fisher - Mt Eureka and significant exploration upside identified across the broader 1,150km[2 ] tenement package.
Rox has completed six Gradient Array Induced Polarisation (GAIP) geophysical surveys at the Mt Fisher and Mt Eureka Projects (Figure 2).
Each of the GAIP surveys were designed to advance the project exploration pipeline by defining potential sulphide-rich chargeability anomalies that represent drill-ready targets along the known gold mineralised trends.
The GAIP survey technique works particulary well at Mt Fisher and Mt Eureka due to the moderate percentages of disseminated sulphide, generally present as pyrite at the known gold deposits and along the mineralised trends within the project areas.
GAIP surveys are also able to cost effectively cover large strike lengths of mineralised trends to identify drillready targets for potential gold mineralisation associated with rich zones of disseminated sulphides.

GAIP survey #2 was completed on E53/1788, also within the Damsel Project area, with the survey located at the southern extension of the Dirks-Nile gold mineralised trend that hosts the Dirks and Nile prospects.
The survey showed two intense chargeability anomalies spanning 400m in strike-length along the eastern side of the sediment-greenstone lithological contact (Figure 3 & 5). The survey area straddles a major north-south gold mineralised structure in a structurally complex area of faulted mafic rocks.
These two intense chargeability anomalies potentially indicate a zone of rich disseminated sulphides similar to the Shiva Project.

The survey was positioned to straddle the sediment-greenstone lithological contact target mineralisation zones to the east of the Wagtail deposit.
The survey was sucessful in highlighting a 600m strike length chargeability anomaly on the eastern side geological contact, and a 400m strike length chargeability anomaly on the western side geological contact. The more intense sections of these chargeability anomalies represent walk-up exploration drill targets.

GAIP survey #4 was completed on E53/1299 within the Taipan Project area, and proximal to the Taipan gold deposit (Figure 8).
The Taipan deposit has historical drill hole results including:
-
20m @ 2.28g/t Au from 100m, including 2m @ 9.85g/t Au from 102m; and
-
1m @ 17.4g/t Au
The GAIP survey was positioned to the south of a moderately gold mineralised zone with the same SE-NW cross-cutting and potentially gold enriching structures, as observed at the Taipan deposit.
The survey identified four zones of high chargeability (Figure 9) and coincident elevated resistivity anomalies – typical of sulphide and silicified mineral systems. Each zone is approximately 200m in strike length and coincident with historical soil and/or historical down-hole gold anomalies, providing drill-ready exploration targets.

Acknowledgment and appraisal of exploration by other parties. |
A number of companies have completed exploration for base metals and gold within the regional Mt Fisher area. These companies include Minops Pty Ltd (1968 to 1971), Tenneco Australia (1971 to 1973), Sundowner (1985 to 1989), ACM Gold Ltd (1988 to 1992), Aztec Mining Company Ltd (1993 to 1994) and Pegasus Gold Australia Pty Ltd (1994 to 1996). Work conducted included aeromagnetic surveys, ground magnetic surveys, regional mapping, rock chip sampling, soil geochemistry (including BLEG and stream sediment sampling) and rotary air blast (RAB) drilling. The Mt Fisher deposit was first discovered in 1936 and mining between 1937 and 1949 produced approximately 4,500 tonnes of ore at 28 g/t gold (Powell, 1990). Sundowner acquiring a 100% interest in the project in January 1986. Sundowner completed a historic estimate of 252,000 tonnes at 5.4 g/t gold to a pit depth of 100 m. Following a period of study, a 250,000 tpa carbon-in- pulp treatment plant was built with completion in September 1987. Open pit mining commenced in April 1987 and continued through to September 1988, and processing finished in late November 1988. Total production from the Mt Fisher open pit was reportedly 218,000 tonnes at 4.3 g/t gold. From 1993 to 1997, CRAE completed extensive exploration with work largely focussing on the Dam prospect where gold anomalism was identified over a 7 km by 1 km area. Work completed included RAB and aircore (AC) drilling with a small amount of RC and diamond drilling follow-up. Delta acquired the Project in 1998 and explored until 2001. They completed additional RAB, AC, RC and diamond drilling. CRAE and Delta defined extensive regolith gold anomalies but were unable to identify any substantial bedrock sources to gold mineralisation. From 1996, Cullen Resources NL (Cullen) in joint venture with Newmont Mining Corporation (Newmont) conducted exploration in the Mt Eureka area for gold and were also involved in a nickel joint venture with BHP. Avoca Resources Ltd (Avoca) acquired the Mt Fisher Gold Project in 2004 and completed geological mapping and soil and rock chip sampling over much of the tenement area. Drilling was focussed on defining further mineralisation along the Dam- Damsel-Dirk gold corridor and extending known mineralisation at Moray Reef, with the internal reporting of Mineral Resources for the both the Dam and Moray Reef prospects. From 2004 to 2011, Avoca completed a total of 158 RAB/AC drill holes for 9,111 m and 64 shallow RC drill holes for 5,188 m. |
Geology
The geological setting is of Archean aged with Deposit type, geological setting and style of common host rocks and structures related to mineralisation. mesothermal orogenic gold mineralisation as found throughout the Yilgarn Craton of Western Australia.

| Drill hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: • easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • hole length. |
Not applicable. Ground geophysical survey. |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. |
Not applicable. Ground geophysical survey. |
| Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low-grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. |
Not applicable. Ground geophysical survey. | |
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
Not applicable. Ground geophysical survey. | |
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). |
Not applicable. Ground geophysical survey. |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
Refer to Figures and Table in the text. |
| Balanced reporting |
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
All data collected for these GAIP surveys is presented in the body of this announcement as chargeability images. |
| Other substantive exploration data |
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
Exploration data has been summarized in an appropriate way to reflect the exploration nature of the project. The survey results are discussed in the body of this announcement and No other substantive exploration results are considered relevant to this release. |
