Mineralization occurs in the intrusives as well as in their country rocks. Complex, mineralized skarn bodies are small- to mid-size and irregular, mostly above porphyries but also underneath intrusive bodies. Gold mineralization occurs Structurally aligned porphyries.

  27. 27. Exploration Challenges • Among the challenges we have in the short term is to guarantee the implementation of future copper producers in Peru and ensure that the initial exploration projects become mining operations. In the long term it is necessary to increase investment in mineral exploration to expand reserves and resources and discovery of new deposits. • Promoting mineral exploration is essential to increase both metal production and long-term resources. • Both financial and technical incentives are required and social barriers have to be removed. • INGEMMET offers 1:100,000 and 1:50,000 scale regional maps covering the whole of the country and most of the territory is also covered by drainage geochemical sampling.

  28. 28. • Regional geophysical surveys (magnetic and radiometric) are insufficient and they need to improve, innovate and implement new methods • Radiometric age data is extensive, but still needs to be expanded. • Isotopic studies useful to distinguish most productive mineralized systems and to identify mineralization sources are still very limited. • Studies of magmatic arcs related to mineralized systems are insufficient. • Private companies, INGEMMET and universities need to joint efforts to increase mining-geologic scientific and technical development of Peru.
