At present, Infrastructure Materials holds five limestone claim groups in the State of Nevada, one exploration permit projects in the State of Arizona, and 3 Manitoba, Canada quarry lease projects with emphasis on cement markets in Reno, Las Vegas, San Francisco, Salt Lake City and California. Mapping and sampling indicate favorable cement grade and quantity of the limestone on the aforementioned lands for large economic deposits.
Drilling, follow-up mapping and sampling programs are currently ongoing to locate and prove out these resources in a systematic fashion. As surface evaluation is completed we proceed to verify these resources by drilling those areas delineated by the surface work.
Additional resource areas are being identified in the US to expand our strategic holdings in anticipation of major infrastructure projects being proposed by State and Federal administrations. Below are detailed property descriptions of the limestone claim groups with currently available data.
Infrastructure Materials Corporation (IMC) has discovered and secured the rights to high quality limestone deposits in several locations in the states of Nevada and Arizona, and in the province of Manitoba. While cement is often the first application for high quality limestone due to its high demand and value for infrastructure, housing and commercial development, there are other valuable applications for this limestone in high demand, producing mineral chemicals used in numerous high value everyday products.
Infrastructure Materials Corp. (IMC) has discovered cement grade limestone deposits in the Nevada deserts, one just north of Las Vegas and another in Northeastern Nevada. IMC is interested in determining if there is a strong enough market for cement in these areas to warrant developing these deposits into high capacity production facilities. The purpose of this study was to develop a demand forecast for these materials for the specific market areas that can be served by these newly discovered deposits.
Blue Nose Claim Group
Nevada, USA
The Blue Nose Claim Group consists of 255 mineral claims located in Lincoln County, Nevada, west of Tule Desert, along the south edge of the Clover Mountains. The property was surface mapped in November of 2008 to define favorable stratigraphic horizons. Results from this sampling indicate 60% of samples are of cement grade material which is clustered to the northwest portion of the Group. The Claim group is 8 miles east of the Union Pacific rail line in the Meadow Valley Wash. Access is via the graded Carp and Bunker Peak roads. Phase 1 drilling consisted of 10 holes. Eight of the 10 holes drilled in the first phase of drilling encountered cement grade limestone assay between 88% and 100% calcium carbonate (CaCO3) with holes 8 and 10 failing to intercept any significant cement grade thicknesses or values within 300 feet of the surface due to their position being higher in the stratigraphic section. Based upon an analysis of the first phase of drilling it appears that the limestone beds are dipping to the west. Strip ratios in the area of the drill holes are considered acceptable. Areas of elevated magnesium were encountered but do not appear to affect the overall value of the cement grade zone. Further drilling will be required to define the full mineralized zone.
The Morgan Hill Claim Group consists of 130 (same amount of Private Land Lease) mineral claims located in Elko County, Nevada, approximately 20 miles west of the town of Wells, Nevada. The claims are situated about five miles north of Interstate 80 and the Union-Pacific rail line. The property is accessed via the I80 River Ranch Exit. The Morgan Hill claims cover BLM lands within the private land "checkerboard" found within a 20 mile radius on each side of the transcontinental railroad. The Morgan Hill claims cover a NE trending package of Paleozoic sediments which include a block of favorable massive limestone that has a 2.5 mile strike length. This limestone exceeds 250 feet in thickness. The claim area contains very significant amounts of micritic limestone within the Devonian Devil's Gate and Nevada Formations. The unit thickness appears to range up to 500 feet and range varying amounts of interbedded MgO. There is adjacent sandstone for a silica supply required for cement. Morgan Hill has topography conducive to open pit mining. Preliminary tonnage estimates are positive with little to no initial strip ratio. Area topography allows access to drill areas with a track mounted drill rig. The property lies within 5 miles of the railhead. It is believed to be situated to competitively reach markets in Salt Lake, Reno, South Idaho and Northern California. Subsequent to the date of this report a 24 hole drill program has been completed on the project identifying three separate cement grade limestone zones of indeterminate thickness. Angle drilling will be required to verify the thickness and continuity of the cement and high grade zones.
The Rock Hill Claim Group consists of 12 mineral claims located in Pershing County, Nevada, approximately 12 miles southeast of Mill City, , Nevada. The Rock Hill claims are accessible from the town of Lovelock, Nevada. The property geology indicates two basic units most likely in the Natchez Pass Formation. Each limestone unit is up to 300-400 feet thick with Siltstone/Sandstone interbeds of variable thickness, noted during the mapping. The property is approximately 12-14 miles from the current railhead in the Dunn Glenn area. Due to the topography, access to this project would be difficult.
The Buffalo Mountain Claim Group consists of 9 mineral claims located in Pershing County, Nevada, approximately 20 miles northeast of the town of Lovelock, Nevada. The geology indicates limestone within the Triassic Natchez Pass Formation. (Based on mapped geology and geochemistry, the outcrops have probable dolomite interbeds) Due to the topography, access to this area would be difficult.
This project is located in Eastern Elko County, Nevada near Wells. The claims are about 5 miles southeast of the town and are made up of 58 lode claims on BLM administered public land. The rail lines and Interstate Highway 80 run through Wells. Limestone beds of the Devonian Devils Gate Formation and the Pennsylvanian aged Ely Formation are exposed in gently dipping beds near the top and the southern extent of the Wood Hills. The beds of the Devils Gate limestone may be 500 or more feet thick according the Nevada Bureau of Mines Bulletin 101, Geology of Elko County. The Ely Limestone is thought to be 1500 feet thick in this area with the lower 600 feet being a conglomerate with clasts of siltstone, shale and limestone. The limestone is exposed in 4 sections of land with several sections of private land adjoining the claim group. The claims have been mapped and over 50 surface samples have been taken that show good cement grade limestone.
The MM Claim Group consists of 31 mineral claims located in Clark County, Nevada, approximately 15 miles south of Las Vegas, Nevada. Work has been conducted to define the potential of the claim group. Samples have been taken with 10% running an acceptable cement grade which may define a specific stratigraphic unit. Surface mapping is completed and on file.
The Royale Claim Group consists of 4 mineral claims located in Clark County, Nevada, approximately 10 miles south of Las Vegas, Nevada. Reconnaissance exploration indicates good quality carbonates on the surface by visual inspection of hand samples and geochemistry. Large areas on this group are accessible by track mounted drilling equipment. Mapping and sampling is completed and on file.
The Pequop Project is found about 35 miles southeast of Wells, Nevada in Elko County. It is reached by traveling south on Highway 93 about 12 miles and then 20 miles to the east and south along a gravel road to the central portion of the Pequop Range. 71 lode claims were put in on BLM administered public land. The railroad tracks are within a half mile of the southern portion of the claims. East dipping and northeast striking beds of the Pennsylvanian age Ely Formation are exposed here. They stretch for over 2 miles to the north from the railroad tunnel in the Southern Pequops. The Ely limestone is mapped as an 800-1500 feet thick unit with some interbedded cherts and sandstones .There is a 250-500 feet thick limestone member in the lower part of the formation that was sampled and mapped. A number of the samples showed good cement grade limestone with some chert beds and silic limestone beds exposed at the base of the good limestone. These silicic rocks could be used for a silica source in a limestone operation to make cement.
The Ragged Top Project is located 23 miles southwest of Lovelock, Nevada and 8 miles northwest of Interstate Highway 80 and the Union Pacific Rail corridor. 59 claims on BLM administered public land are present here. These claims cover 14 exposures of limestone seen in the gently rolling hillsides. The area has low relief and is also underlain by a granitic intrusive rock that has recrystalized and bleached the limestone beds. Some silicification and altering is seen in the old prospect pits on the property. The low relief makes estimating any thickness difficult. The claims have been mapped and a number of surface samples have been taken.
This project is found in eastern Lincoln County, Nevada about 120 miles northeast of Las Vegas, Nevada. 69 lode claims are located here about 35 miles southeast of Caliente, Nevada. Access is south from Caliente along state highway 317 to Elgin and then another 15 miles south on the dirt road to Lyman Crossing where the road goes east for 17 miles to Lime Mountain. The railroad line runs north-south along Meadow Valley Wash through Lyman Crossing and Elgin. The claims cover the steep sided hill shown as Lime Mountain on the 7.5 minute USGS map of the area. Mississippian Monte Cristo Limestone beds are found here overlain by a 600 feet thick dolomite unit in the center of Lime Mountain. The Monte Cristo Formation is the same one that is found at the Blue Nose Project 8 miles to the west. It is about 500 feet thick and is a light gray to white clean limestone with only traces of chert. Minor dolomite interbeds were seen during mapping and sampling of the property. The limestone crops out in a north south line that is 2 miles long and is approximately 1 mile wide. This project would be able to supply cement needs to the Las Vegas and Southern California markets.
The Jumbled Mountain Project is in eastern Lincoln County, Nevada about 125 miles northeast of Las Vegas, Nevada. 186 lode claims are located over three isolated outcroppings of limestone. This area is approximately 8 miles southeast of the Blue Nose Project. The Southwest Block of these claims has a 300 feet thick limestone bed that overlies some dolomite units. The main Jumbled Mountain Block has 100-150 feet of limestone either in fault contact with the lower dolomite or there is a non-conformity between two beds. The Northeast Jumbled Mountain Block has several isolated outcroppings of limestone that are found high in ridges and may also have a fault between them and the underlying dolomite beds. These areas have been mapped and sampled. 283 surface rock chip samples have been taken in the claim block.
The Burnt Springs Project is located in the Burnt Springs Range 6-10 miles west and northwest of the Union Pacific railway at Caliente, Nevada. The project area is composed of 51 load claims which are in three separate blocks in the central part of Lincoln County, Nevada. The Burnt Springs claims are located on thick bedded limestone sequences of the lower Highland Peak Formation which have minimal dolomitic overburden. The southwestern most claim block in the Burnt Springs group is located on the 100’ thick Peasly member, which is steeply dipping to the northeast. The formation members of the other two claim groups are not known, but are generally massive thick bedded micritic to fine crystalline limestone. They are dipping moderately to the north east. A total of 76 rock chips samples have been taken from the Highland Peak Formation in the area of the claims.
Limestone beds in Northern Arizona about 23 miles west of Seligman were identified in our research for limestone in Arizona. The Blye Canyon area is south of Highway 66 about 8 miles along the border of Yavapai and Mohave Counties. The limestone bed found here has been mined for a number of years by Chemical Lime Company in a site about 5 miles north of the project area. Infrastructure Materials Corp US has State of Arizona Mineral leases on 3.5 sections of land. The basal unit in the rocks in this area is a 300 feet thick dolomite with minor chert and limestone beds. Overlying this is a clean gray white limestone that may be 100-150 feet thick. The gently north to northeast dipping rocks have little relief in the low rolling hills. This makes estimating the thickness difficult. The project area has been mapped and over a hundred samples have been taken from this unit. Many cement grade values were found in the samples but the thickness of the unit is not known. Exposures of the unit to the east give a150-200 feet thickness for this limestone bed in that area. This project could provide cement for the Las Vegas, Southern California and Phoenix markets.
The Tres Alamos Project is located 65 miles east of Tucson and 18 miles northeast of Benson, Arizona. Infrastructure Materials Corp US has leased 14 sections of State of Arizona land in the Little Dragoon Mountains and the area just north of them in Cochise County. The railroad lines are approximately 12 miles to the southeast of the project area. Rocks exposed in the Tres Alamos Wash and the Palomas Ridge to the north, consist of Cambrian Bolsa Quartzite, Mississippian age Martin Dolomite, Mississippian Escabrosa Limestone and the Pennsylvanian age Horquilla Limestone. The Escabrosa has a lower dolomite unit about 200 feet thick and upper limestone beds that is up to 500 feet thick. The overlying Horquilla limestone beds are up to 800 feet thick. The Earp Formation overlies the Horquilla on the Palomas Ridge. It is a siltstone and limey sandstone and is about 1000 feet thick. All these units have a moderate east dip and northwest strike in the area of Palomas Ridge. The exposure of the limestone beds stretch over 8000 feet in the NW-SE direction on Palomas Ridge and for about 2000 feet in the SW-NE direction. In Tres Alamos Wash the beds dip to the southeast and strike generally northeast. The limestone beds appear to be draped over a large plutonic body and cut by high angle faults in Tres Alamos Wash. The outcrops of Escabrosa and Horquilla limestone in Tres Alamos Wash are fault bounded and comprise 7 different hillsides on the north flank of the Little Dragoon Mountains. All of them in Tres Alamos Wash are smaller than the outcrops of limestone on Palomas Ridge. The production from this project would be situated for the Tucson and Phoenix areas.
