Bethlehem property owned by Bethlehem Copper Corporation Ltd. is located in the Highland Valley areas of British Columbia, Canada.
The main orebodies, suggestive of porphyry copper deposits, consist of the East Jersey orebody and Jersey one.
Following the preparation of a feasibility study made in cooperation with Sumitomo Metal Mining Co., Ltd., Sumitomo, in February, 1961, concluded an agreement with Bethlehem whereby Sumitomo provided the financlng of 5, 500, 000U.S.dollars to put the property into production.
The mill plant, with a rated capacity of 3, 300 short tons per day, was erected, in late 1962, and then mining commenced on the East Jersey zone as an open pit mining operation on December 1, 1962.
Ore reserves of the East Jersey pit was calculated at about 3, 300, 000 short tons at 1. 13% Cu after allowing for dilution.
The mining operation was done by a contractor, which provided the following main equipments on the work. 1-40R Rotary Drill, 2-4½cu. yd. Shovel, 4-Trucks 32 ST, 4-Trucks 27 ST.
During the period of March, 1963 through February, 1964, the ore was hauled at a rate of 4, 100 ST per day to the crusher, and the waste rock (including protore) was hauled at a rate of 11, 200 ST per day to the waste rock disposal area or to the protore stock pile area.
Stripping ratio waste/ore was 2.71.
In February, 1965, serious sloughing occurred on the wall, so that mining of the East Jersey was discontinued and mining equipments were moved to the Jersey pit, when all the ore in the East Jersey pit had been nearly mined out.

The principal property of Copper Mines & Enterprises is situated in high plateau of Bolivia, known as the “Altiplano”, which has an elevation ranging from 3, 800m at Lake Poopo to 4, 500m at the topmost mine workings, 90km wide extending from the Argentine border on the south to Lake Titicaca on the north, lied between the Cordillera Occidental on the west and the Cordillera Real on the east.
The copper belt “Corocoro formation” runs parallel west side.
The deposit of Chacarilla mine is located roughly in the center of this metalliferous belt.
And was known one century before, for it's high grade copper ore. The principal mineral explored there is the native copper, and the mineralization is located in are shoots founding in this mine consists of three elements.
The general course is N40°W and worked only by hand, therefore the amount of picking result disturbed by inconvenient location and a continental climate.
We acquired the original option of the prospect 1959, and after investigation and prospecting our company bought this mine from the owner 1960.
Then we established in this desert, water supply, housing, electric plant repairing plant, dressing plant etc. first stage comepleted 1963.
As we confirmed excellent results in the deep parts by boring, so we are forming a plan to extend the scale of mining and development, at the second stage we have 13, 000T/M plant in contemptation afew years after.
And in spite of a change of government, we are striving to bring copper cocentrates for our country.

The Ma On Shan Mine, the metamorphic contact iron are deposit, located in Kowloon peninsula, has been operated since 1906. However, in 1952 as the grade of the are was getting gradually low, the Japanese mills refused to take it successively unless the, grade up operations were under control of our company. In 1953 the Mutual Trust Co. Ltd. which is the ownner of the mine asked our company to operate the mine as the joint venture, and the agreement was concluded in that year. The first processing plant having the capacity 120, 000 tons of concentrate per annum, was completed and started its production in 1954. In 1959 the open cast was mined out and the mining site had to be removed into the under ground. At the same time the processing plant was capacitied up partially. In 1963 the 110M adit was driven through. In 1965 the production was raised up to 150, 000 tons of concentrate per annum, and the facilities and equipments of the plant have been increased accordingly.

The Condestable Copper Mine is located on the sea-coast near the city of Lima in Peru.
This mine which belongs to the Nippon Mining Co., Ltd., took two years of prospecting and development and one year in construction work before being brought into production in 1964.
The ore deposit is divided into groups of ore bodies A, B, C, D, E, F and G, each of which consist of parallel veins lying close to one another.
The present production capacity is 300 tons per day, giving a monthly output of 190 tons in terms of metallic copper. A total number of 250 persons are employed here.
