MANEATER BRECCIA

The Maneater Breccia is a high potential with a well-defined target below the current limit of drilling. The target is located nearby to NMR’s Palmerville Project and close to existing infrastructure. Based on extensive research, NMR considers the target prospective for gold and copper below the current level of drilling.

The breccia has a single drill diamond drill hole completed in 1995. The 363.8M long drill hole (dipping at -53 degrees) cuts across the breccia and reported 300m of breccia containing variable mounts of sulphide, reaching between80% and 100% sulphides at ~240m down hole.

While pyrite is the dominant sulphide within the breccia, assays and other observations of drill core contained with previous company reports highlight a lead (galena) and zinc (sphalerite) dominated base metal assemblage. Chalcopyrite is noted in drill core below 134m down-hole depth. Other features such as cavities and low grades of gold (except in surface veins where gold assays of up to 2.05g/t have been recovered) suggest that the level of investigation of the breccia pipe is above the higher-grade gold and copper core at greater depths. The metal zoning is indicative of the same metal zoning observed at the >1Moz Mt Wright Breccia Pipe located near Ravenswood, approximately 280km to the south.

The base map is the regional 1:5M geology map of Queensland. The tenement and target are located proximal to existing mining infrastructure at Chillagoe, Mareeba and Cairns.

Features of significance reported by previous explorers

  1. Rock chip samples from a vein adjacent to the breccia pipe of 2.05g/t Au and 65g/t Ag (sample number s40208; Stevens-Hoare & Robinson 1985).
  2. Other samples returning grades of 14.9% Pb (Sample number s40266) and 9.45% Pb (Sample number s40017; Stevens-Hoare & Robinson 1985).
  3. The breccia pipe forms a prominent topographic high (Maneater Hill), with both breccia and mineralisation present at the surface.
  4. The breccia is clast-supported and contains sulfide contents up to 100%.

Significant observations reported in diamond drill hole log (*note that the diamond drill hole was oriented at a dip of -53O, across the vertical mineralised breccia pipe). 

  1. Increasing base metal abundance with depth.
  2. Diamond drill hole intersected sulfide-bearing breccia over a 300m intersection (not true width) of the breccia from 48m to 356m down hole depth.
  3.  Lead-, zinc- plus pyrite-dominated sulfide assemblage in the majority of the drill core.
  4. Chalcopyrite (CuFeS2) reported below 134m in drill core.
  5. 2m interval at 8g/t silver assay from sample Q26238 between 74m and 76m down hole depth. 
  6. Open space cavities noted throughout drill core but decreasing in abundance with depth
  7. The interpreted age of the Breccia Pipe (Late Carboniferous – Early Permian) is the same as Resolute Mining Limited’s Welcome and Mt Wright Breccia pipe located approximately 360-380 kilometres to the south respectively.
  8. The breccia forms a distinctive topographic high, similar to Mt Wright, Kidston and Mt Leyshon, as well as other breccia-hosted deposits found in north Queensland.
  9. Cavities noted in drill core suggesting high levels (i.e. close to the Earth’s surface at the time of intrusion) within the breccia system.
