The Java property is underlain predominantly by northwest trending, westerly dipping clastic and volcaniclastic rocks which either conformably underlie or are in fault contact with andesite flows and lapilli tuff of the Naglico Formation, a package of Middle Jurassic Hazelton Group mafic to intermediate volcanic rocks. In the Java a 500 by 800 metres, northeasterly-elongate nonfoliated biotite granodiorite to granite Eocene stock, which he referred to informally as the Java pluton.
Mineralization near the southern end of the Java pluton includes widespread, quartz-pyrite-molybdenite sheeted to stockwork veins cutting granodiorite and hornfels. Also observed is granodiorite-hosted gold- and bismuth-bearing, ribbon-banded, quartz-molybdenite-pyrite veins contain traces of chalcopyrite near the southernmost end of the Java pluton; vuggy white quartz veins containing clusters of pyrite, chalcopyrite, molybdenite, tetrahedrite and arsenopyrite hosted in andesite to the west of the Java intrusion; and auriferous zones of disseminated pyrite and clotted to disseminated pyrite-arsenopyrite in quartz veined and sericitized andesite to the northwest of the pluton. Near the interpreted northern contact of the pluton, two styles of mineralization are noted: 1) clots and disseminations of pyrite, chalcopyrite and molybdenite in bleached and altered miarolitic granite.
Near the southern end of the pluton, quartz veins are white and rarely exceed 5 centimeters in width, with vein densities averaging closer to one per metre. Traces of pyrite, molybdenite and rare chalcopyrite were noted along vein selvages. Grab samples from this area ranged up to 0.056 per cent molybdenum (Assessment Report 24829). Copper, gold and bismuth values are generally low. Similar mineralization was noted in the sparse outcrop and float farther northeast within the pluton, suggesting that quartz-sulphide veining could be pervasive within the Java pluton.
Also near the southern end of the Java pluton ribbon-banded, white to vitreous, light grey quartz-sulphide veins occur in outcrop and as float. Veins, in outcrop, exceed one meter in width, and the bands of sulphides within the veins were comprised of fine grained dark grey pyrite and molybdenite with rare chalcopyrite. Assays ranged up to 0.235 per cent molybdenum 0.05 per cent copper, 0.74 gram per tonne gold (Assessment Report 24829).
A number of styles of alteration style include sericite-pyrite envelopes adjacent to sheeted and stockwork quartz veins within the Java pluton, pervasive sericite alteration in one outcrop of strongly fractured and quartz-veined granodiorite, intense bleaching and potassic alteration of miarolitic granite.
The 2010 and 2013 soil geochemical programs on the Mo Java property have clearly confirmed the large-scale, high-tenor molybdenum-in-soil geochemical anomaly outlined by Kennecott in the mid 1990's. It is irregular in form but the central core has a diameter of at least 600 metres. It remains partially open on both the north and south ends.
WORK HISTORY
From 1995 and 1996 by Kennecott Canada Exploration Inc conducted an airborne geophysical survey (250 line-kilometre; electromagnetic, magnetic and EM (VLF)), built a short ATV trail into the property, cut grid line, and collected soil (320 samples) and rock (101 samples) geochemical samples, the latter during the course of geological mapping on the property. Kennecott's mapping, rock sampling demonstrated that the anomalous stream sediment and soil geochemical anomalies originating on the Mo Java property were associated with a significant porphyry molybdenum mineralizing system, while the airborne geophysical survey helped to outline the extent of the various lithologic units.
In 2006, Stephenson (2006) spent one day on the property, utilizing a helicopter to undertake spot reconnaissance geological mapping and rock sampling (6 samples).
In 2010, C.J.Greig and Associates Ltd collected 179 soil samples and in 2013 they collected a total of 115 soil samples in order to fill-in gaps in on the 2010 grid.
