MAGMA CHIEF PROGRESS IS REPORTED BY
 SUPT. KUNKE
Promising Property at Super for Rushing Development Work at a Great Pace. Pro missing Indications Found.


 of the Magma Chief Copper company. in his report to the board of diree- tors of the corporation, dated Octo- Der l, conveys some interesting in- formation regarding the development on the property. The superintendent is neither optimistic nor pessimistic. His facts. however. are very encour- aging to the many stockholders in the company throughout the country.
 The report follows:
 Superior. Ariz.. Oct. l. 1917. To the Board of Directors of the Mag
 ma Chief Copper Company: Gentlemen:
 The second progress report sub mitted to you was dated July 20. 1917. At this time the machinery at the Magma Chief plant had been in op- eration for about three months and had been giving very good satisfac- tion- The Watson tunnel then meas ured 993 feet. and the formation for the last 200 feet was in the red irou- stained. highly altered and leached prophyry that so closely resembles the ore-bearing porhyry in the Mag ma mine.
 On the north of the Magma Chief property. the old Baltimore tunnel had been cleared out. and ventilating ma chinery had been ordered The Ob- ject of resuming work in this tunnel. after many years of idleness. was to explore, at a depth of about 175 feet. the manganese showing on this part of the claims.
 Since then the work in the Watson tunnel has progressed steadily. At the present date the tunnel is in 1490 feet. In addition to this. several cross cuts have been run. as follows: At $50 feet a cross-cut 26 feet south At 1050 feet a cross-cut 20 feet south. At 1150 feet a cross-cut 15 feet south- At 1250 feet a cross-cut F feet south At 1250 feet cross-cut II feet south At 1250 fee. a cross-cut II feet north. At 1450 feet cross-cut s feet south.
 The object of these cross-cuts was to determine the width of the Assure at regular intervals as well as to out line the extent of the porphyry in the Assure.
 The porphyry was first encountered at 675 feet. and the tunnel passed through it at 1900. showing a length of 525 feet. The crOss-cuts at 950. 1O50 and 1l50 showed this porphyry to vary from 15 to 25 feet in width. and numerous samples taken in the croSs-cuts as we'll as the main drift from a trace to nearly an ounce and carrying from a trace up to SS.50 in gold. The finding of the silver and gold values throughout the entire body of this tightly leached porphyry Is indeed very encouraging and a num- Der of mining men and engineers who examined the tunnel agreed on the point that this mineralized porphyry was the ore-bearing formation and should be explored at a greater depth without delay.
 When it was found that the adja- cent limestones in the tunnel had flat- tened, in pitch, by more than ten de- grees. the distance to the L. S. & A contact was computed as being abont 400 feet farther than first estimated. This, together with the fact that we had passed through the top or cap of the ore-bearing pOrhyry. hastened the decision to explore this porphyry at depth by means of diamond drilling.
 This decision was reached at a di- rectors' meeting at Hayden, Ariz-. September 29. 1917. As the running of a diamond drill will leave us no surplus power. it was decided to stop work in the tunnel and drill the re- maining distance to the l.. s. & A. contact by means of diamond drill also.
 We are now preparing to run four cross-cuts north. The first at the 700 foot point, where we first encountered the porphyry; the second at the $50 foot. where the porphyry is 2s feet wide, and the best silver and gold
