Briggs, Ariz., June S.-(Special cor respondence of The ReQublican.)-As- ceEding Buzzard's Roost gulch the first object Of interest that presents itself (about two miles from Briggs) is the Trade Mark five-stamp custom mill. and just beyond is the Moonlight, property belonging to. Denver people through which runs vein carrying good values in gold-about 100 tons treated at the Briggs mill producing $27 per ton. "A contract has been let for the first 200 feet of a cross measure drift on this vein that is expected to strike the ledge at about 300 feet.
 These Denver capitalists own a group of eight claims in connection with this property, the most promi nent being the Swallow mine, which las been worked for the past ten years. The shaft on the Swallow Is 236 feet to water level and some 1,5O0 feet of development work has been done Upwards of 4,OO0 tons of ore from this mine have been treated at the Briggs mill with an average re- turn of $20 per ton. This mine has been hitherto worked as a gold prop Csition but there was a great quantity of rich copper ore exposed in working out the gold ores and it is intended with view of mining this copper ore, to sink a vertical shaft which will strike the ledge below water level. where the ores are expected to become sulphides. Preparations are being made for erecting a steam hoist and work upon the tunnel and shaft is to be commenced right away.
 
 The extension of the Swallow on the west, the Golden Wonder, has shaft 150 feet in depth. Five hundred tens of ere taken from this shaft have been milled with return of s10 per ton. The development work has made showing of about 2.000 tons ready to be brought to the surface, but it will not probably be raised until a project ed reduction works, to be erected on this property is completed, the haul to the Briggs mill being too expensive.
 The Amazon group Of claims, about five miles northwest Of Briggs, were next visited. These nine claims be- longed to the late Bob Groom and are now in the hands of the administrator, MT. Hawkins. who, it is stated, has bonded them to Colonel Carter of New York city. The lodges on these claims are immense Assure copper veins which in places are from 100 to 300 feet in width. Included in these claims are high grade gold ores which have been proved by actual milling tests to contain values of from $9 to eral development work will be imme- diately commenced on this group.
 The Constellation group, joining the Amazon on the north, comprises four claims. Shafts of fifty and thirty feet in depth have been sunk on the ledge and a drift run ninety feet crosscut and 160 feet in the vein. Besides this the veir, has been stripped in many places. exposing ore carrying gold in quantities. Fifty tons of ore milled produced s2O per ton on the plates. the tai,ings, which also con tained considerable values, being, in the absence of facilities for their proper treatment, thrown away.
 The ledge is from four to six feet between the walls and can be traced on the surface for 5000 feet. This group is bonded to Captain Evans of Phoenix
 At the head of Whipsaw gulch is Morgan and Dougherty's camp. They have a number of good copper pros poets on which they are doing, devel- opment work, also two promising gold tons of ore from which mi.ied an average of $50 per ton. Messrs. Morgan and Dougherty have been in this district for many years industriously prospecting its mineral wealth and some, if not all, of their will in the future no doubt become valuable producers.
 
 From the last mentioned camp crossed over to the Buckhorns, where pulled up at Messrs. Woodburn and Lords camp, and after long morning ride gratefully accepted their proffered hospitality in the shape of as good a camp dinner as a man with a noun ain appetite could wish to sit down to. They are doing prospecting work On numerous claims which are making a
