After introducing SYZX75 wireline coring hydrohammer, we launched the study on its assorted drilling technology and field trial in Xiaoqinling gold ore deposit of Lingbao City of Henan Province. Field trial results showed that unit efficiency per month, average hour efficiency, roundtrip length and core recovery percentage in cracked formation could be improved obviously.
2019628&ensp·&enspOre is a classification of rock that describes an economically viable block, from which metal or minerals can be extracted profitably. An ore deposit model is an extensive organization of information required to adequately describe the state of a mineral deposit that has been transitioned into an economically mineable category.
QUEBEC Torontobased Power Ore has completed the digitization and 3D modelling of the former Perry coppergold mine at its Opemiska project near Chapais. The mine produced about 9 million tonnes of ore at grades of 2.16% copper and 0.14 g/t gold. Falconbridge operated the Opemiska complex Springer and Perry mines from 1953 to 1991.
This study outlines a model that relates the polymetallic coppergold porphyry, skarn, and veintype deposits within the Tongling ore district. This model provides a theoretical basis to guide exploration for deepseated and concealed porphyrytype Cu (Mo, Au) deposits as

An integrated ore prospecting model for the Nyasirori
2019121&ensp·&enspLi SP et al. (2016) established a comprehensive geologicalgeophysicalgeochemical prospecting model of the Mwamola BIF gold deposit, which has played a guiding role in the gold ore exploration in Tanzania in recent years. For example, the BIF type gold deposit PL10957 has been proved to contain nearly 8 t of (332) + (333) type gold resources.
