nave Nls4tfu the Twin Peaks Ain
 ing company's property again sftel
 an absence of three months. Mors
 work-good work-has been done
 in that time than one would deem
 possible. A station has been cut CD
 the 200. the shaft sunk 30 feet be
 low and still going down. cages in
 stalled and buckets abandoned and
 every facility for the speedy and ec
 onomlcal moving Of ore and much
 has been increased and bettered
 This work has been done under gu.
 perintendency of Alex. Fraser. one oi
 the owners and one of the best niue
 superintendents know, and while
 the cage would not work properly
 when brought in. all changes were
 made at the mine. and now every
 thing is turning smoothly
 Some time ago I wrote about .he
 Twin Peaks mine. which is % rifles
 from Duncan, Arizona. and at he
 time expressed my pleasure in the
 property, ueeming it a good one. Tbis
 time. after a more thorough exaL,-
 ination to and below the 200 level
 am even better pleased. for there is no question now that a mine is here. On the 900 level the vein was found as permanent and carrying as
 good values as on the surface. aud the body of ore is better. Of course at this depth the ore is sulphide, but even here it is noticeably leached. and is readily amenable to con centration or cyanidihg, but the values are there as at the surface Indeed, some Of this ore at depth runs exceptionally high. and if one wishes to 'be shown he only has to roast some Of the ore from the lower levels to a white heat and then pan il. when he will get a string of gold that is perfectly surprising. ' am ot the opinion after I learned about assays and banning that the whole vein Of about five feet will carry sI0 and upward per ton. The ore is easily mined, one round of shots often breaking down 10 tons. This Is due to the fact that the walls are perfect and clean. and between the wall and the ore is of ten quite a little taic But if this is absent. breaking to the wall leaves that portion clean. with all ore thrown down.
 Favorable Location.
 The deep workings. where perma- aent development is going on. are at the east end Of the property. right at the foos of the mountain forming he Twin Peaks. This is a most fav- orable location. Paralleling the vein s & very wide dyke of short grained vellow porphyry. and not more than 200 feet from the vein Al the 'oot of the twin peaks is a large 5Iowout Of the same Nharacter of 9ohphyry. T. is the oninioH that at this lsTter point where the vein enters or comes in contact with the qcrpnyry. a good ore body will be 'Ound. and the north drifts on both he I0H and 900 levels are being run .n this Dorphyry as ore making and with this in view explorations will shortly hegin to determine the mat Ter. Should it prove as believed. here will be a great body of ore along that dyke, as the vein in which iu work has heretofore cen cred is noticeable Tor more than 2h ulies. and t diDs toward the porphy- v Careful estimates make the drain age level. or local water level. about $50 feet, and the shaft is now being sunk to that gepth with all possible spee% In fact much water is making in the shaft al this time, when but 240 feeJ down When water level is reached the enriched zone will have been entered and even better ore should be uncovered.
 Tn princiraI owners ~- -h's prop arty--Alex. Dan Fa- ~ Joseph Fraser an s'f Quse-are simply business men ahose activi- lies have in va elled them to get into mining Consequently they have no theories to prove. and no previous experience to be guided by and this IS mighty good thing and SO they develop the property in a business like way. They kept in ore all the time. They were scared if for a little the vein dipped out of the shaft and they lost their ore. They wouldn't listen for a min ute to the advice of miners and exDerts who wanted them to follow a hunch or go digging in the country rock for what might be there. They were aILeT ore ana lutg ufuh 'CS anything whatever interfere with their staying with it So, they now have a good many hundred feet Of on the Twin Peaks property. and every inch Of it is in ore. Now. though, as the stability of the regular ore vein on which they based their hopes originally has been demonstrated, they are willing to do some dead work fn the possibility that some of the De- liefs Of miners and others may turn out correct: consequently, when the main shaft Is dswn to $50 feet they intend crosscutting to the big DOT phyry dyke and nrosrecting it a bit. Right now they are drifting in the vein toward the porphyry blowout, and as development proceeds the significance of this. if any. will be learned without a dollar Of extra ex- eense. because they would Of course driff on their vein and in the ore rhute. This kind of work inspires confidence and shows that mining may be conducted in a common-sense xay if the men af the head do not deviate from set purpose.
