In the Rising Sun mine the low level has > been extended 20ft, making a total distance : of 931 ft. The country continues the same as when last reported. The manager of the Phoenix and Tairua Dreadnought mine reports that the country is still very .bad. It is best described as a conglomerate. The total length of this tunnel is 522 ft. The manager of the Kirikiri mine reports that the main drive is in broken country. .., • ' From the appearance of the grounds now, .;-;(■>;■ however, he thinks that'in*a*few* feet the country will be solid again. "A little water ia coming out of the face. > ' ■ According to the manager of the Bendigo mine, the low level lias been extended 17ft for the week, making a total of 80ffc r for the second contract. The country rock is lighter , in s colour, and full of • mineral, : with small quartz stringers. On the Silver King reef the men continue to break ore in the stopes* - The "manager of the Tararu mine' reports v that No. 4 level east of the crosscut 7is in 139 ft. The country is greatly j improving in ■'~, "; appearance, and is more congenial andesite rock.:'.; The ; present face is a mass of quartz and ! mineral veins ; interlacing ground of a splendid description, and striking into the ~reef at all angles. • The manager of the, Karangahake mine reports that in breaking down in Manuel's winze ' last week 51b of picked stone was - obtained. The ground'has improved a little, there are numerous, mineral;veins. The Taukani • prospecting;; level , is" in : 17ft. The reef measures 20in in width, and there is a fair amount of sulphides in the ore.:,. • ■ i During the past week work in the Missouri mine has-been .-! confined, to carrying along - " the'leading stope on the Red Mercury ; reef. •. The reef is a strong. body of ore, measuring about 4ft in width, • and, although . it. is travelling ; in f i an excellent class :of andesite country, the prospects are not as encouraging as 5 formerly. The ? manager, however, expects that the ore will improve in value : as the stope ,is advanced. „„ ~ * Driving west on the course of Conway's , lead in the Point Russell mine has been continued with two shifts. The quartz, stripped has been broken down, and, although •. .. no ?old has been seen, the leader looks very promising, carrying with it zinc blende, and a little bright mineral. Two men have been driving north on the course., of the break during the past week through a splendid . sandstone country. The. break is'carrying a . rubbly formation of quartz, in which col-nit's of gold have boon seen. - . ' In the stopes above the intermediate level in the New Waitaia mine the reef is 6in to ■ Bin wide, and-produoing" fair grade ore. Driving north of the slide at the intermediate > level the -reef is over If wide, and, although so -far only f occasional prospeote have been obtained, the reef is entering a - of country, and should improve shortly. ■- Crushing is now proceeding at -the battery, and the ore shaping for a freturn. -.
