This report summarizes results of the third year's work of the Mineral Exploration by means of drilling and tunnelling explorations carried out in the Iscaycruz Area (40 km2), the Republic of Peru. The purpose of this project is to examine relationship between geological structure and mineralization, and to confirm lateral and vertical continuity of the mineralized zone, by means of drilling exploration and tunnelling exploration in this area. The Iscaycruz Area had been extracted as a favorable area where economic ore deposits would be expected to be emplaced, by the results of the Mineral Exploration in the Oyon Area (860 km2 ), which was carried out during the period of three years from 1979 to 1981. The Iscaycruz Area is located about 150 km north of Lima, in the backbone range of the Western Andes. Geo1ogically, Mesozoic sedimentary rocks are wide1y distributed in this area, forming...

This report summarizes results of the exploration works of the progressive stage of the Mineral Exploration by means of drilling and tunnelling explorations carried out during the period of three years from 1982 to 1984 in the lscaycruz Area (40 km2), the Republic of Peru. The lscaycruz Area had been extracted as a favorable arca where economic ore deposits would be expected to be emplaced, by the results of the early stage of the Mineral Exploration in the Oyon Arca (860 km2), which was carried out during the period of three years from 1979 to 1981. The purpose of this project is to confirm the existence of economic ore deposits, in the selected areas of Limpe area and Limpe-South area in the lscaycruz Arca, through the implement of investigations such as tunnelling exploration and drilling exploration both on the surface and in the underground. The Iscaycruz Arca is located about 150 k...

Regarding the "Mine Development Survey Works at the Area of ISCAYCRUZ of the Republic of Peru" promoted by the Metal Mining Agency of Japan as one of its projects for the fiscal year of 1985, a series of various mill tests in laboratorial scale for the samples from the ore deposits of ISCAYCRUZ have been carried out. The results of the tests are summarized and reported herewith.

Complying with the Peruvian Government request in 1985, preliminaly survey as well as the subject feasibility study, infrastructure to be related to develop the mine and economic intention for the district was conducted at the Iscaycruz district, which indicated high potentiality of occurrence of copper, lead and zinc deposits under the scheme of "Cooperative Mineral Exploration" since 1979. The survey was carried out by the feasibility study team which comprised with six specialists from Japan International Cooperation Agency (JICA) and Metal Mining Agency of Japan (MMAJ) as a special participant together with the five Peruvian counter partners of Instituto Geológico Minero y Metalúrgico (INGEMMET).

This report describes results of the first year's survey in FYl998, implemented in the Urubamba river inferior area of the Republic of Peru, under the technical cooperation for the mineral exploration. The survey was conducted with an aim to effectively select promising zones from the extensive survey area in a short period of time, by means of satellite image analysis, existing data analysis and integrated studies of survey findings of an arca upstream of the Amazon in eastern Peru, which covers the Ucayali River Basin and its upper streams, the Urubamba and the Tambo, where the metallogenic zoning has not been clarified in detail. Simultaneously, the technology transfer to the INGEMMET - Instituto Geológico Minero y Metalúrgico, the Peruvian counterpart for the survey, was carried out concerning the methods of survey and analysis. Collection and analysis of existing data and the sate...

This report describes results of the first year's survey in FY1998(Phase I) and the second year's survey in FY1999(Phase II), implemented in the Urubamba river inferior area of the Republic of Peru, under the technical cooperation for the mineral exploration. The survey was conducted with an aim to effectively select promising zones from the extensive survey arca in a short period of time, by means of satellite image analysis, existing data analysis and integrated studies of survey findings of an area upstream of the Amazon in eastern Peru, which covers the Ucayali River Basin and its upper streams, the Urubamba and the Tambo, where the metallogenic zoning has not been clarified in detail. The Urubamba river inferior arca covers an arca of about 65,500 km2, spreading over the 27 quadrangles of the 1:100,000-scale topographic map issued by the National Geographical Instituto of Peru.
