 gold, and in some cases manganese: , ■. . - .- . . ; 



a. Consolidated. A good strong lead with much minerafized walls, 

 ""■ ■■-•- and silicious vein matter, more or less banded and' partially 

 ''■••■■' ■ crystalline. High values for about 6 meters on foot and hanging 



walls in quartz with some manganese. 



b. Fianza, Continuation of the "Consolidated" vein. 



c. Major Mines. Showing frozen walls and much mineralized country 



rock in a few cases. 



4. Quartz with copper and free gold; also galena and zinc in some cases;' 



a. Union Jack, Camp Four. One sugar quartz lead and one ■ massive 



quartz v ith high values in copper and free gold. All much; 

 oxidized and enriched. Both narrow and poor in depth. 



b. Copper King. Some free gold with a considerable amount of copper 



and manganese. 



c. Major Mines. One lead contains a stringer rich in gold, galena, 



pyrite, and copper. . 



5. Quartz with no free gold: 



a. Kelley (noi'th slope). Four veins occur, 1 to 5 meters wide, con- 

 taining tellurides of gold with pyrites, or ores of gold of the 

 telluride type. 



6. Quartz with free gold and cinnabar: 



a. Ascension group. A lead on the Kias trail, much oxidized, contains 



beautiful blood-red crystals of cinnabar the size of fine sand. 



b. Batwaan. One quartz lead 1 to 1.5 meters wide. 



7. Quartz with wire gold or plate gold (rare) : 



a. Major Mines. One vein occurs in which free gold is visible in the 



ore. 



b. Madison Group. Plate gold foimd in crystalline quartz stringer in 



the country rock. (F. T. E.) 



MINERALS IN THE BENGUET LODES. 



The following minerals have been found in the various Benguet leads. 

 A few of their characteristics as they occur in the district are given with 

 each. 



QUARTZ (SiOz). * 



Milk-white, bluish-white almost opaline and in clear-cut hexagonal crystals in 

 druses in the ores, sometimes cellular showing leaching. It is the gangue mineral 

 in the majority of veins. 



CALCITE (CaCOa). 



Milk-white often associated with rhodochrosite ; also in stringers in quartz 

 veins. 



RHODOCHROSITE (MnCOs). 



A pinkish massive mineral in certain calcite veins. 



PYROLUSITE (MnOa). 



Soft black masses filling pockets and crevices, or as dirty, black incrustations, 

 and as. bands, in the calcite.
