MINING NOTES.

The new Empire shelter at Rollin, near Crittenden, will give great inn petus to mining in the southeastern portion of Pima county
 Mr. w. R. Wemple came in from the Southern Belle yesterday. He has about thirty men employed in and about the mill and mine.. B. N. Braj- avich, a first class miner, is under ground foreman. John Knudson is superintendent. The amalgamator at the mill is Holly Cove, an experienced mill man, from the Smuggler Union at Telluride, Colo. Everything about the place is moving smoothly along and the prospects for a big camp are excellent
 Gold, when refined from all impuri- ties and alloys of inferior metals, is denominated pure. This means gold of twenty-four carats, and this is the standard recognized by the mint mas ters and dealers in gold. AS matter of fact, however, there is no gold so pure. Gold of twenty-two carats is about as pure as it can be got. It has two parts of silver or one part of cop per. The copper darkens the color of gold, while silver lightens it in color Twenty-three carat gold is occasional ly seen, which means a half carat of silver and of copper. Ordinarially eighteen carat gold is the best gold that can be had
 Kamloops, British Columbia, is lia- ble to become the center of consider able mining excitement Like the Chi cago fire the mining boom in Kamloops had a strange beginning, and was started by trifiing casualty. Two bulls were combating on a foothill a farmer going by in wagon recog- nized one of the beasts as his prop erty and separated them. The strug- gle had been a severe one, and the sur face was overturned in several places. The farmer noticed a piece of rock of peculiar color and had it assayed on his first visit to town, and was amazed when his certificate showed value of s45 per ton in copper Work was done on the claim, and it shows up well defined vein of copper ore. Now, the entire country is staked out.
 The Eagle Pass Guide says. Mines and mining in the state of Durango are now receiving a good deal of at tention from outside investors They could hardly turn their eyes toward a more promising state. It is proverbial that all mining is more or less a lot tery; yet there are mining properties of proved value, many of them, with in easy distance by good wagon roads of the International railroad in Du- rango. One mine, yielding an average of only sixty ounces of silver per ton is prOspering, despite haul of forty miles to railroad. There are others within half days haul of the rail- road whose average assays show much more silver than the above, and they lack only adequate capital for their development to yield large and certain returns. In the Panuco de Coronado district about thirty-five miles north east of Durango city a mining camp has been formed. St. Louis capital ists are at the back of this. They nave dcquHeu VdludDle properties ana such is their confidence, want more in the same neighborhood They are only about fifteen miles from rail. road transportation by good wagon road. A general feature of the silver mines of the Panuco district is that tc a moderate depth the ores can be treated by what is known as the patio prOceSS-cruShing and amalgamatiOI by quicksilver. Deeper they become refractory, but at the same time more valuable Sulphides predominate, ant shipment as crude ore to smelters al Velardena or Monterey is decidedly advantageous. This holds good O. many other districts adjacent to the railroad in the state of Durango.
