  • Mining and cutting a 35K super gem crystal Belemnite Pipe.

    Mining and cutting a 35K super gem crystal Belemnite Pipe.

    In early December 2020, our mining company was prospecting on the Donna's Rush opal field about 50 kilometres north of Coober Pedy Australia. 

    Donna's Rush is a field named in honor of John and Yoka Dunstan's late daughter. I knew her a little personally and can attest to what an amazing person she was, she certainly brightened the day of anyone she interacted with and is very much missed by all who knew her, not least her family. 

    So with that in mind, it is fitting that some of the most beautiful opal we have ever found has been from the relatively small field of Donna's Rush.

    This particular day we winched into a mine that had been dug recently with a tunelling machine with little trace left behind. I tried out a battery powered drill we spent over a thousand dollars trying to see if it was feasible, you can see in the video the small holes it made before the battery overloaded and cut out. Turns out it's too soon for that tech, we will have to stick with 240 volts and elbow grease for the time being. 

     Just as we had almost finished checking the entire claim, i found some small 'feeders' of trace in a patch of beautiful opal level (the chocolatey weathered sandstone around the opal in the video), and as I was cutting them out, it was very fortunate that a few crumbly chips fell away from the pipe, exposing the end as seen in the video. This piece will be for sale at our mining companies accounts following:

  • We dig 8k per ounce Dead Horse Gully super gem shells. Early October 2021..

    We dig 8k per ounce Dead Horse Gully super gem shells. Early October 2021..
    Taken over 4 days in the beginning of October 2021. I return to an old favourite, Dead Horse Gully to see if we could pillarbash some of the beautiful dark crystal opalised shells I simply cannot forget from many years ago. Sure enough, we were fortunate to find a belemnite pipe with a few carats of stunningly flawless world class super gem, a full shell that was quite dirty but also yielded some absolutely mind blowing crystal, and quite a few other bits and pieces that will be appearing in jewellery and rough opal parcels at worldclassopal.net Thanks to @KimberleyOpal at Graceopal.pty.ltd for the loan of half the equipment! 😋
    We will add updates to this blog showing the new jewelllery that is produces from this beautiful material. Thanks for watching!

  • Mining absolutely stunning natural Australian opal on The Farm, Coober Pedy Australia.

    Opal in the wall on The Farm opal field, Coober Pedy.

    Several years ago we were in Coober Pedy and a bit hard up for places to find opal.

    I went for a fly over on Google maps and found this open cut i knew had been started over 20 years ago but had now been completed to the opal level. We went to check and sure enough it had been abandoned so we had a scratch around for a few days, and here are some of the results in a quick video! Shows opening up, digging in the opal level, some of the stunning precious opal kingstones, and of course, the finished one of a kind pieces of beautiful Australian opal jewelry that resulted. Miing explosion moving mullock..fast

  • Mining by hand on Dead Horse Gully Circa 1999 Excerpt from 'Pillarbasher'

    Mining by hand on Dead Horse Gully Circa 1999 Excerpt from 'Pillarbasher'

    Quite a few years later my younger brother Shannon and I were champing at the bit each morning to get to the field. After a sauce with pasty and a farmers union iced coffee, we were totally pumped. Off down the dusty track in the crusty ute to our claim in the desert. In those days we had what is known as a 'self tipper' or automatic hoist. Dead Horse Gully was a favourite field we dubbed "red sauce gully" because of the stunning unusually blood red colour in the opal. On one spot we drove 200 odd feet by hand which is blasting and removing the dirt with 2 x 20 litre buckets on a barrow. We wheeled the buckets to the base of the 45 ft shaft and transferred them into the 50 litre bucket on the automatic hoist, and away she went, up and over and back again. Ironically, when we arrived and were installing the winch, we found 3 $2 coins at the top of the shaft and said, maybe its a sign we will find 6 million! Turned out to be 6 thousand, barely wages at the end of it, but an experience I would probably do over for free.
    At one point in that claim we were trying to open up a 9 inch air shaft that was blocked with gibbers about 30 ft down. We devised a simple plan to drop a sausage of anfo (ammonium nitrate/fuel oil) or 'nitro' locally. With the safety fuse alight, Shannon dropped the plastic bag down the hole attached to a skinny frayed rope with the idea that a small jolt at the bottom would release the sausage and we would crack the blockage. I still clearly remember the look on Shannon’s face when he brought the rope up and the bomb was still attached! There was still a smidge of time on the fuse so I grabbed the rope and hastily dropped it in the hole. Right then we realized the ute was only about ten feet from the hole and could suffer some damage from the blast. I quickly grabbed a short handled shovel and covered the hole thinking it may stop some rocks from flying out. Cerrracckk!! Off went the shot as we woo hooed and leaped with excitement at the adrenaline rush, being not too far from the hole. As the dust cleared, we noticed the shovel had disappeared, then looking upwards saw the shovel spinning at rpm about 150 ft in the air on it's way back down. Thankfully everything missed the ute and we survived. We literally had a blast, got the shaft cleared and the air flowing but all for very little opal in the end. One of the partners was always totally beside himself and yapped his face off every time a bomb exploded, our trusty red heeler cross mining dog Goof, Goofaloofa or Loofy as we liked to call him most. He loved the back of the ute better than anywhere else on earth, like any other bush dog. If we approached speed on the Stuart highway the wind would catch Loof's eyelids and lips, turning him into a freak. Brilliant for a laugh after a hard day mining, being full of endorphins and pretty 'surfed out'.

     Watch to see the process we followed mining this claim, and some of the spoils at the end...
