Midnight Juniper, Arizona

Midnight Juniper is a porphyry copper project located within a World-Class District just northwest of the Morenci open pit. Distal porphyry-style mineralization is observed in windows beneath post-mineral volcanic cover.  Base metal mineralization occurs both as steeply dipping veinlets and as sub-horizontal mantos-style, bedding replacements. The veinlets have a preferential NE-SW orientation, which is also noted to be a control on mineralization within the Morenci deposit.

Targets include: 1) intact porphyry copper system concealed beneath post-mineral cover, 2) significant supergene enrichment, analogous to nearby Morenci deposits, and 3) potential for high grade zones of mineralization as both skarns and CRDs.

*Nearby mines and deposits provide context for the project, but do not necessarily indicate similar size, styles or grade of mineralization within the project
