THE COPPER
 BASIN SECTION.
Satisfactory Progress Being Made in Development of the Copper Basin Gold and Copper Mining Com
 pany's Property.
Important Strike of Good Ore Made in the Cross Cut at the One Hun
 dred Foot Level.

Quite a good body of sulphide ore
 was recently encountered in the cross
 cut on the Black Prince mine of the
 Copper Basin Gold and Copper com
 pany. Samples ofthe ore can be seen
 at the company's office- The cross
 cut is being run at depth of 1O2 feet
 for the purpose of determining the
 width of the dyke on which the claim
 is located. The cross cut has been
 run over 100 feet and no signs of
 wall have yet been encountered. The rock for the entire distance has been
 miueralized, containing sulphurets, though no big values are obtained, but the opinion of mining experts who have examined say that none may be reasonably expected as the rock they are in is a capping and that the real ore body may be expect ed to be found when they have cut through this capping.
 At one point in the cross cut, a sort of vein or Assure was encountered in which the sulphides in the rock were found in much larger quantities than in other portions of it, and drift has been run in on this. It was in this drift that the ore body mentioned above was encountered, and it is growing stronger and richer as pro gress is made on the drift. While work is still being pushed on the cross cut this drift will be continued for some distance and this ore booy followed. The dyke is such mon ster that the work of opening it up compared with that of an ordinary ledge is slow. The ore encountered in the drift gave value of Sl0.S0 in gold and Sl.60 in silver. The ore also contains a percentage of copper, but | no determination of its exact value in | this metal was made. A considerable | flow of water has been encountered in | the east end of the cross cut.
 On the same dyke, several hundred ! feet further south than the Black . Prince and about 250 feet lower, a shaft has been sunk on the Anna Bell claim to depth of P feet and | much richer ore has been found. It | contains ten per cent copper besides Its values in gold and silver. This | claim belongs to the Pyramid com pany.- 4 shaft has also been sunk 50 feet deep on the Iron Prince, another claim belonging to the Pyramid com pany and located on the old U. s. ledge, now known as the Prosperity ledge. In this shaft solid sulphurets were encountered on each wall, while between these bodies of sulphurets there is a good body of carbonate ore which assays S30.00 per ton. The The indications here. are excellent for developing into a good property. The stock of the Pyramid company has not yet been placed on the market, the officers of the company having done the work on it so far at their own expense.
 The Copper Basin Gold and Cop per Mining company commenced operations about the first of last Nov ember, and since that time they have done over 600 feet of development, all of which has been very important, as showing the possibilities of the property.
 The Journal-Miner has frequently expressed an opinion of the probabil- ities of a great mine being opened up in that section, judging from general indications. This is not the opinion of an expert, but is gratifying to know that such an eminent mining engineer as Prof. Blandy, who recent ly examined the property, as well as others of less renown, entertains the same views. After thorough exam ination of the formation and of the work done by the company, MT. Bland y recommends:
 "l. Continue cross cutting forma ton at bottom of shaft on Black Prince" claim until both walls are reached, then sink shaft another 100 feet deep and again crOss-cut forma- tion as above described. It can be expected with reasonable assurance. that better values will be obtained at that depth; and should values still average $500 per ton, there are quan- titles enough of iron sulphides to make a valuable mine.
 ''2. The next point to be examined and proven is whether the belt is more valuable at other points. I have selected another place some 5000 feet farther south, on the "Su- perior" claim, where the outcroppings look more favorable to me, and advise some development at this place.
 B. Sinking on the shaft on Anna Bell" claim should be continued, where more valuable ore has been found
 A. These properties are of such large proportions that could not ad- wise any additional expenditure until the places mentioned above are thoroughly prospected and the value of the main dyke is determined, as this is the important question. All energy should be concentrated for purpose. Here. if ore of sufficient value be found, additional work should be done to patent or hold out lying claims.
 D. This quartz porphyry dyke is very large and should you develop only one rich place in these workings you have large and valuable mine.
 II may say that the work is well directed and handled, and no fault can be found with the progress of devel- opment.
 Iaonday Club Meeting.
 The regular meeting of the Mon day club was held yesterday after noon. The literary programme was dispensed with and he entire session was occupied wita business and with election of officers for the ensuing
