Greetings from the team at Central City and Black Hawk:
The race to finish the Mill has entered the final lap, and the team is sprinting to the finish. We reached an important milestone earlier this week on the critical path to completion. The week got off to a cold start, and as W.C. Fields might have said, zero degrees was not fit for man, nor beast, nor concrete. But by Wednesday the temperature had risen and the guys were back at it finishing the foundation and preparing for the installation of the coarse ore bin. Take a look at these videos and pictures which will show you the work that went into pouring and preparing the bin’s foundation.
As to the Mill equipment, the pieces are coming together nicely. Pictured below is the newly installed Denver Duplex Jig which is positioned between the Ball Mill and the Rake Classifier. The Jig is a gravity recovery tool that takes advantage of the differences in specific gravity of mineral particles coming out of the Ball Mill. Because gold is much heavier than the other metals and minerals (specific gravity for gold is 19.32 vs. 11.34 for lead vs. 2.65 for quartz), gold will preferentially sink faster than the lighter minerals. The Jig creates a concentrate of the heaviest metals which are then further processed to separate out the gold on the shaker table. It's an important step in removing the gold from its rocky home.
Stay tuned for further developments. We just added another master electrician to the team so that we can expedite wiring and connecting the many machines, motors and pumps that will power and deliver the finished product. If you have any questions or concerns, please feel free to send me an email and I’ll do my best to respond. After the last Note, I imagined this communication:
I say to you all what I would have said to infamous James Bond villain, Mr. Auric Goldfinger – I can see the finish line, and we are getting closer every day.
Cheers, GS Mining Company
