Regional Geology. Geologically, most of the part of the Bundi district is occupied by rocks of Vindhyan formation which forms the part of Great Vindhyan Basin extending from Xxxxxxx in Bihar to Chittorgarh area in Rajasthan. Rocks of Vindhyan range in the area area are divided into Lower Vindhyan and Upper Vindhyan. Lower Vindhyan comprises of Jahazpur and Upper Vindhyan include Kaimur, Rewa and Bhander groups. Lower Vindhyan i.e. Jahazpur is separated from Kaimur group by conglomerate horizon which marks the break in sedimentation before deposition of Kaimur i.e. unconformity. Kaimur, Rewa and Bhander Series of upper vindhyan are also separated from each other by unconformity. Jahazpur group of Lower Vindhyan is generally calcareous. Kaimur and Rewa is generally arenaceous while Bhander is arenaceous and calcareous in nature. General statigraphic succession of rock types exposed in Bundi district is as follows:

Source: Modified and generalized lithographic sequence after G.S.I. (1981). The rocks of the area belong to the Lower Bhander group. Main rock type is lower Bhander sandstone (Bundi Hill sandstone) Structure No fault, fold or any geological disturbance is observed in the lease area. The general strike is in the NW to SE direction and dip is almost flat to gentle inclined, of sandstone beds.
Regional Geology. The Saindak Cu-Au deposit is located in the Chagai District, Balochistan Province in the north-western corner of Pakistan. The Chagai calc-alkaline series Magmatic Belt is a well known, economically important geological belt hosting porphyry Cu deposits. The Chagai Belt runs about 480km along and inside the Pakistan border with Iran. The rock types of the Chagai Belt comprises mainly plutonic rocks; granodiorite, xxxxxxx diorite and quartz monzonite (granite→diorite series). The mineralisation at Saindak is hosted by the Amalaf and Saindak sedimentary formations of Upper Cretaceous to Oligocene age. The Amalaf Formation is predominantly made up of siltstones, whilst the Saindak Formation is comprised of marls, volcanic agglomerates and andesitic tuffs. The tonalite stocks (quartz diorite porphyry) intrude the Amalaf sedimentary rocks.
Regional Geology. The mineralisation at Duddar is associated with the Jurassic carbonate and clastic sediments in the Paleocene-Eocene collision zone between the Indian and the Iranian/Afghani plates. The Duddar area is of Loralai to Xxxxxx age and displays evidence of an extensional basin, likely developed during rifting and break up of Gondwanaland. Variable facies and debris flows indicate the onset of extensional rifting in the Duddar Member coinciding with the syn-diagenetic development of mineralisation. The stratigraphic sequences at Duddar are typified by rapid facies changes, with few internal consistent marker beds.

Regional Geology. The south Eastern Rajasthan is one of the geologically important terrains where rocks of Archean of Upper Proteroxoic age are found. Archeans which are oldest rock formations are represented by rocks of Bhilwara Supergroup followed by Aravalli Supergroup of lower Proterozoic age and Delhi Supergroup of Lower to Middle Proterozoic age. The Upper Proterozoic Xxxxxx Igneous suite and Erinpura Granite follow the Delhi Supergroup rocks westwards. The generalized Geological Succession of south western Rajasthan is given below:
Regional Geology. It is made up of a sequence of Cenozoic volcanic rocks, resting on a basal sedimentary section of Mesozoic age, which in turn are intruded by igneous bodies associated with the East border of the Batholitic complex of Sinaloa. • The volcanic rocks belong to the two large subdivisions established informally to the Sierra Madre Occidental by XxXxxxxx and Xxxxxx (1977), which are the Lower Volcanic Complex and the Upper Volcanic Supergroup. • The upper volcanic complex is formed by felsic volcanic rocks, mainly by ignimbrites, tuffs, spills of rhyolitic composition. These rocks are found in most of the region forming the topographic highs and the thick folder of the Sierra Madre Occidental in the form of plateau, to this sequence is assigned an age of the Middle tertiary, ranging from 34 to 27 m.a. The igneous bodies ranging from granodiorites to quartz monzonites, tonalities, and diorites, the first being dominant, there is wide variation in the range of ages within the same region, but with a tendency to be more young to the East (Henry C.D., 1975).
Regional Geology. The regional geology belongs to Vindhyan System derives its name from the Great Vindhyan Mountains, a part of which is found to form the prominent plateau – like range of sandstone to the north of the Narmada valley, particularly in Bundelkhand and Malwa. It occupies a large basin extending from Dehri-on-Sone to Hoshangabad and from Chittorgarh to Agra and Gwalior, surrounding the batholithic mass of Bundelkhand Granite. The upper Vindhyan are exposed in the Great Vindhyan Basin. They consist largely of sandstones and shale with sub-ordinate lime stones, the sandstones forming extensive plateaus around and to be the south of the Bundelkhand Granite mass. The sub-divisions are shown in the accompanying table.

Regional Geology. The area is within the Omineca Crystalline Belt; a NW trending belt dominated by plutonic and high-grade metamorphic rocks. Regional geology is presented in Figure 3, the source of which is G.S.C. Map 1736A by Xxxxxxxxx-Xxxxx. Rock units present in the immediate area of the project include: Jurassic age Xxxxxx Plutonics comprised primarily of quartz diorite, monzonite and granodiorite but also include greenstones, amphibolites, mafic schists, meta-wackes and lesser limestone of the Carboniferous and older Anarchist Group. This sedimentary and volcanic package occurs as isolated rafts or roof pendants surrounded by the younger intrusive. The Valhalla Intrusions (granite and granodiorite) of Jurassic-Cretaceous age are distinguished from the Xxxxxx Plutonics by their porphyritic nature and general lack of foliation. The Xxxxxxx Group is Eocene porphyritic felsic intrusions that occur as plugs and xxxxx in the area. These trachytes, andesites and lesser tuff and shale interbeds outcrop in erosional remnants on the property and in fault bounded outliers throughout the Okanagan region. Fine-grained mafic xxxxx are the youngest intrusive rocks in the area, and are related to regionally significant Miocene plateau basalts. Several xxxxx occur within the property. PROPERTY GEOLOGY AND MINERALIZATION The only source of property geological information available is the above noted regional geological map by Xxxxxxxxx-Xxxxx. Some specific geological information/notes, directly associated with known mineralization within the property, has been found and is included within each of the mineral showing descriptions below. The following property geological information is based on Xxxxxxxxx-Kluit’s regional mapping (Figure 3). The St. Xxxx Creek is primarily underlain by Xxxxxx Plutonic Rocks which are covered by a thin layer of alluvial material (gravel, sand and soil). The British Columbia Geological Survey/Department of Mines mineral inventory file “BCDM MINFILE” notes that a designated mineral showing occurs within the St. Xxxx Xxxxx Project area as follows:
