Several exploration prospects exist within 15km of the Mineral Resources that compose the Viscaria Copper Project. The most prospective are interpreted to be: Nihka, Bahpagobba, D Zone Extensions to the North and South, West Nukutus and Kurravaara.


The Nihka magnetic anomaly, located 2km south of A Zone, has not been previously explored. Avalon has recently completed a bedrock auger drilling program which defined an area of copper anomalism of at least 600m long, partially overlapping with the magnetic anomaly, and open to both the east and west. Trace visible chalcopyrite was identified in 4 holes.

D Zone South

The D Zone South target is defined by an extension of the magnetic anomalism at the main D Zone deposit and historic drilling results including VRC0079: 4m @ 0.6% Cu from 49m.

D Zone North

The magnetic anomaly that defines D Zone can also be traced to the north. One line of historical drill holes traversed this anomaly and intersections including 1m @ 2.4% Cu, 1m @ 1.6% Cu, and 1m @ 1% Cu were recorded.

Other Prospects

Several other exploration prospects within 15 kilometers of the Viscaria Copper-Iron Project have been identified from historic data and regional exploration datasets. Sunstone is currently progressing plans to advance some of these prospects.


The Bahpagobba target is defined by an EM anomaly adjacent to the northern end of the A Zone orebody. Bahpagobba has good copper historic geochemical sampling and drilling results including:
D2094: 7m @ 1% Cu from 123m; and
D2470: 1.5m @ 1.8% Cu from 60.5m.

West Nukutus

The West Nukutus Prospect is defined by a magnetic anomaly of similar magnitude and scale to D Zone. Little historic exploration appears to have been completed in this area. The closest historic drill hole (150m to the east) intersected up to 0.3% Cu and 0.5g/t Au but did not intersect the magnetic body.


Another very highly ranked regional prospect is Kurravaara. This prospect is defined by historical copper and gold geochemical sampling with rock chips containing up to 1g/t Au and 0.9% Cu. This area also contains historic workings, which exploited vein/disseminated copper-gold mineralization concentrated in a regional scale fold hinge. The mineralisation styles appears to be of a similar style to that of the historic Pahtohavare Cu-Au Mine, situated approximately 10km to the south of Viscaria.


Competent Persons Statement

The information in this report that relates to exploration results is based upon information reviewed by Mr Malcolm Norris who is a Fellow of the Australasian Institute of Mining and Metallurgy.  Mr Norris is a fulltime employee of Sunstone Metals Ltd and has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves”. Mr Norris consents to the inclusion in the report of the matters based on his information in the form and context in which it appears.
