The information in this presentation has been obtained by Renaissance from its own records and from other sources deemed reliable. However, no representation or warranty is made as to its accuracy or completeness.
Widespread polymetallic mineralization in Pioche, Highland and Bristol Districts occurs as both fissure veins and mantos in Cambrian carbonates
Carbonate replacement deposits, minor skarn, and qtz-sulfide fissure veins are associated with Late Cretaceous (100-90 Ma) granite intrusions
Minor lamprophyre and qtz porphyry dikes are present, porphyry source of mineralization may not be identified to date
District may be nested carbonate replacement deposits around Manhattan stock dismembered by Basin and Range faulting

Project Summary
Manhattan Gap Project
• Historic Ag-Pb-Zn-(Au) production from fissure veins and mantos (CRD), and Au-Ag qtz veins
• Approx. 6.3 M tons grading 3% Pb, 7.8% Zn, 0.03 opt Au, 3.9 opt Ag, minor Cu and Mn production
Pioche District Historic photo
Historic Pioche, Highland, Bristol Districts Production
Mineralization dominantly in Combined Metals Bed in Pioche Shale (first carbonate above Prospect Mtn Quartzite)
Other mineralized units include: Susan Duster limestone in Pioche shale, Lyndon limestone, Davidson Blue limestone in Highland Peak formation, and Mendha limestone
Stratiform mineralization is best developed along E-W “ore channels” e.g. Caselton
Manhattan Gap project covers northeast trending fissure veins and dike swarm in Upper Cambrian and Lower Ordovician Menha formation
The major stratigraphic targets in district are preserved at depth on Rengold project

Geology and Rock Chip GeochemistryAu
Rock Chip Au (ppm)
Au values range from detection limit to 14.4 ppm Au
1 ppm Au values occur in iron-oxide quartz + sulfide fissures and mantos
Highest Au values occur along east-west break in the range at Manhattan Gap and Arizona Peak

West Graben Target - Cambro-Ordovician unconformity under shallow cover on east margin of contact metamorphic aureol
Eastern Shelf Target – Shelf of favorable stratigraphy on northeast projection of fissure vein swarm
East Graben Target – Cambro-Odrovician unconformity with high grade historic mines in fissure veins on each side of graben
