 der Creeks, consisting of twenty -eigh
 claims. While the development i
 meager there is enough to show tn
 marks of wonderful copper propert!
 from surface indications.
 The Niagara mine has five openings
 The deepest point attained is about 2;
 feet. These openings disclose ledg,
 of copper ores to a width of from foul
 to ten feet, which carries fair pei
 centage of copper. This ledge or veir
 is found in porphyry lime and unite
 in close proximity to granite dyke
 running parallel with the trend of the
 Niagara which is northeast and south
 west.
 The Omega has a shaft 80 feet deer
 on Assure vein. The walls are well
 defined. It has a sedimentary fill, but
 has punches of malachite ore. When depth is attained it ought to produce good grade of copper ore.
 The Palestine vein has tunnel run in on porphyritic granite. The full width of the vein is not fully deter mined. A sample of the face of this tunnel gave 500 value in copper.
 The Alice group, close to the Omega and Palestine shows good values in gold. The mountains are of a volcan- ic origin, having been worn down by erosion. They have a rugged and characteristic erosive feature. Cop per creek in scoring away the ground in its course leaves the sides from the creek in some places a perpendicular night of five hundred feet to the apex disclosing an immense porphyry dyke of iron and diorite.
 The porphyry and diorite dykes show up bands of quartzIte and quartz carrying fair per .centage of copper. In the bed of Copper Creek there are several bands of quartz fully two feet in width, carrying sulphides. The water running in the creek shows by chemical analysis from five to eight per cent copper. Below the junc- tion of Copper creek with Boulder creek we come to the westerly side of this porphyry dyke. Here is a granite dyke to width of about 1000 feet, running north east and southwest parallel with the porphyry. Adjoin- ing the granite, on the westerly side is an immense iron dyke about 2,GOO feet in width and several miles Tn length. This iron dyke crosses Boul- der creek north easterly.
 The company has fourteen claims in this property. The Iron King and the Iron Mask, located across the dykes. The other twelve are located abreast 6,O00 feet in length, 100 feet wide. The Iron King takes in part of Boulder creek and running parallel with the creek. No great depth has been attained on this property. The ore carries high per csntage of iron.
 Along with this iron there are bands of gossan rock. A large ore body of this cahracter is naturally divided into three zones, beginning at or near the surface with the zone of where the material is known as gossan. It then passes down to the zone of enrichment where the so-called black oxide occurs and finally at a greater depth iEto the zone of the sulphides. These zones are often extremely irregular, but gener- ally we'll defined. The gossan of this dyke is in the main porous limonite. It results from the alteration of the pyritic to ores from which nearly every thing, but the iron, has been carried away by percolating waters, leaving the iron of a hydrous oxide (limonite). The gossan usually. con- tains also a large portion of the gold of the original ores, but the copper is mostly carried down to form the rich sulphides in the next zone. Such are the marks of this great iron dyke. All it wants is to sink to the sulphide ore.
 All those properties want is a little money iudiciously expended to devel. op three good copper properties. There are several other properties in the Hillside district that have a very outlook. The Hillside mines proper, 1 did not see, but ad- joining the Niagara company's proper ty there is some eight or ten claims belonging to Lawler and Wells that have a good showing for copper ore of ! good grade most of it which has been mined bearing shipment. A railroad is what this camp wants to bring it to he front.
