 A company has been formed to dredge the Colorado river near the mouth of the Grand Canyon. It is said the bars carry payable values in gold There have been many at tempts to work the bars of the Colorado but all have proven dismal failures Let us hope the new at tempt will be the exception.
 The Warren District.
 The Warren district is continually presenting new surprises. The lat est one is reported from the Uncle Sam workings of the southwest shaft of the Copper Queen. The dimen- sions of the ore body have not yet been proven It is conungious to similar developments in the Shattuck ground where it joins the holdings of the Copper Queen. Tn the Shat tuck an important discovery of lead silver ore has been made in the Iron Prince claim The extent of this ore body nas not been determined but if has been encountered on both the 4O0 and GOO foot levels. on the Calumet X Arizona new discovery is reported to have been made. on the 1900 foot level of the lloatson shaft. The ore body has been pcne- tratcd for 20 feet with no limitation in sight This district is certainly wonderful in development of ore bod ios that were never thought of. The limitation of ore bodies were figur- ativelv decided upon but the develop ments and continuation of the ore bodies almost makes the mineraliZ- ed area inimitablc. The further the work goes. only proves the necessity of going further The ore bodies may end in China An assertion that they end at the Mexican bord- CT is two narrow.
 The Toronto company continues to develop the Black Rock Limited near Wickcnburg They are extracting ore from the 150 foot level and mak- ing test runs. For this purpose they have installed two foot Hunt ington mills and four conccntrators.
 The property is a large low grade proposition measuring about 150 feet in width carrying gold. silver and copper The latter is in the form of glance sam Powell formerly owned the property and still has a large interest in the company. Tn" company is said to have fund ol $1OO. 900 for development purposes.
 sam Powell has other claims on the Hassayampa that are now being investigated by prospective purhasers.
 An Awakening.
 The reiuvenating of old mines, claims and districts in Arizona is more in evidence now than for years past There is an awakening in every locality. Tn Pima county, ac- tive work is going on everywhere Around Helvetia there is develop ment on copper claims At Twin Buttes new ore bodies are being op- encd up by the extensive develop ment work There is bonding of gold claims in the ArivaCa district and the Empire Zine company is bling up ore on the dumps of the old San Xavier claims. In the Rose mont district. the LeWissohns are adding to their already large hold ings. Tn the Dragons promising zinc properties are being opened up.
 In the Woolfram area tungsten is being continually shipped to Phila- delphia, with a cry from the chemical house for more, as the ore supplied carries a high per cent of tungstlc acid. The Centurion X Keystone are both shipping ores. The Texas Ari- zona is making regular shipments of ores.
 There is also a reported strike of high grade ore in the property of the Arizona United Mine company on the 700 foot level.
 At the Commonwealth, extensive development work continues and l much machinery is being installed The leasers on the Black Prince are
