Mineralised intervals are presented in the following tables
Mineralised intervals are calculated using a rolling 0.20% copper with up to 5 metres of internal waste. Intervals shorter than 10 metres are not reported.

The drilling program and geological studies at the Constancia project are being reviewed and approved by Leonardo Diaz (MAusIMM), Norsemont’s Qualified Person under NI 43-101. Core samples are cut with a diamond saw, with one-half of the core placed in sealed bags, and shipped to ALS Chemex Assay Labs in Lima, Peru. The program includes an extensive quality control program for assaying which includes the systematic use of standards, blanks, and field duplicate samples. Secondary laboratories are also used for check assaying. All intersections were determined using a rolling 0.2% Cu cut-off and up to 5 meters of internal waste. Due to the disseminated characteristics of the deposit and homogeneity of the mineralization, all intersections are to be considered true width.
