Naseby Gold

Orders taken on 50% deposit for the 4" basic dredge. This dredge with its light weight, portability, and affordability makes it appealing, both to the weekend prospector and the serious dredger alike.  Small enough to slide into a ute, light enough to be packed into remote areas, the 4" makes an excellent one-man dredge.  This model is equipped with pontoons that have increased stability over previous models, while remaining compact and lightweight.  The frame remains essentially the same as previous models.  It's a sturdy bolt-together design which allows the dredge to be disassembled into smaller components for ease of transport.  Assembly requires only a few hand tools.

The dredge can be equipped with either the 5.5HP Honda engine and HP350 pump, or the 6.5HP Honda engine and HP400 pump for additional power.  The HP400 is a very efficient 3" x 2" pump with a high flow, "progressive bite" 5-vane impeller.  This is the only pump in the industry designed specifically for the 6.5HP engine.  We highly recommend this engine / pump package for anyone who dredges to greater depths or at higher altitudes.  This dredge is equipped with our "sure-flow" coupler, which essentially eliminates all surface rock jams.  Our unique one piece jet / flare assembly not only reduces downtime caused by rock jams, but it is extremely light, and outlasts conventional steel jets by four to five times!

This dredge uses the highly acclaimed "wave classifier" which has proven to greatly enhance fine gold recovery, by eliminating the problems associated with processing low-grade sand.  The classifier develops a pulsing, or 'jiggling' action, which prevents the dredged material from loading up under it.  By shedding the low grade particles, the fine gold can drop out of suspension earlier and accumulate under the classifier, where it is safe from the turbulence and disturbance caused by the larger rocks travelling through the sluice.  The rear portion of the sluice box utilises "Hungarian" riffles for maximum efficiency and the dredge is equipped with Nomad matting for the ultimate in fine gold recovery.  No other 4" dredge even comes close. The basic 4" dredge fitted with 5.5hp and HP350 pump inclusive of GST @15%, Duty @5%, and allowing $NZ700 for freight to NZ, a landed cost would be close to $NZ6247. Extra cost would be involved with the addition of larger motor and pump and Thomas T80 compressor.
