Hikurangi Coal Company

Hikurangi Coal Company. This company owns the largest mine in the district, covering 800 acres of freehold and 150 acres leasehold. The coal is semibituminous and of the same geological age as the Greymouth and Westport coal. The mine is equal to a production of 500 tons per day, but the present output averages 600 or 700 tons per week. There are three openings; one is on the level of the outcrop, the second is worked by a self-acting incline, and the third is a dip, from which the coal is hauled by a twenty horse-power steam engine. The main drive is fully half a mile long, and is under a cover varying from page 561 thirty to fifty feet thick, while the seam of coal varies from seven to sixteen feet thick and is free from bands. The mine is entirely self-drained, and employs forty men, the output last year being 30,000 tons.
