Prospecting Drill and the Underground Digger. We prospect for opal with a 9 inch auger drill. When promising material is discovered we drill a 3 foot diameter shaft to a depth that bottoms on the opal bearing level. When, what appears to be payable material is found, we lower a mechanical digger down the shaft.Truck and blower then into the Agies. The dirt is extracted by a "blower" which, in reality, is more akin to a giant vacuum cleaner. When the truck is full, it is taken to an "agitator"- a modified cement mixer where the extracted dirt is washed for the duration of the weeks mining activity. Up to 10 truckloads of dirt go into each batch of wash, which accumulates and wears down to a much smaller concentrate by the end of the week. Rough Opals from the Tailings.
Then, we manually sort through the concentrated tailing and pick out the gems, often none, but once every few years hard work is rewarded by discovering a pocket of truly beautiful gems.

It is difficult to achieve total accuracy in representing opal with digital photography for the following reasons. The human eye sees objects slightly differently to that of the digital camera because of the different mechanisms involved with how they register light. Each persons eyes see a little differently to the next persons eyes. There is a tendency for variation in many computer screens that are manufactured and calibrated a little differently to their competitor products.
Example; a LED screen will have a lot more contrast than a Laptop Screen. The opal colours and patterns as seen in actuality are a result of a complex combination of refraction, diffraction, diffusion and reflection of light from the opal structure. When an opal is viewed with different light sources and different light intensities the effect of the stone can change a little from one light source to the other. The total aggregated combination of these facts means there will be some degree of inaccuracy when representing opal with digital photography.
To compensate for these factors I like to list our products by including still photos and a movie with all care and techniques applied to represent the item as accurately as possible.
