San Juan Summary: Leviathan’s lead project is the claim block of San Juan. The property has extensive historic work, data collection and drill results. San Juan contains two main systems;
Leviathan has an option for 100% ownership of the project with low total costs which include a work program, cash payments and share transfers. The first year exploration costs are very low with with no shares payments required.
Location: The project area is 1850 Hectres over 8 mineral claims. The site is located 1.5 hours North of Culiacan, the State Capital of Sinaloa Mexico. The local town of Bardiraguato is located 15 minutes from the property and offers most services. The property has a 16 Km network of roads that offer open access to all key target areas. Paved highway, water and electricity are available at the main entrance to the property. The main entrance is 3.5 Km from San Juan Valle, the first work area. San Juan is in the heart of the Sierra Madre Mineral Belt. There are a number of large operating mines and deposits in the region:
Geology: The formations underlying and shaping the San Juan Hill (Cerro del Guajolote) belong to the subalkaline (calcic) series of igneous rocks. The Road 24, from Badiraguato to La Lapara, were the San Juan property is located, cuts through multiple hills and shows outcrops that range from augite-rich (silica-rich) massive rhyolites (Km 45) to feldspar veined ryholites, ryholitic breccias, tuffs and vesicular ryhodacites (San Jaunico, Km 50). About Km 56, at the town of La Lapara, the rock series begin to turn into massive dacites with various degrees of acidification shown by more or less abundance of qz amigdales, qz veinlets or veins. Coarse (upt o 1 inch), concentric, acicular quarz crystals and amygudales have been widely observed in the veinlets of ryholites around Km 48 of the road to La Lapara. There are evidences of epithermal influence that are possible to observe were the igneous rocks become oxidized along fractures, fault planes and shear zones, showing mostly microcrystalline hematite together with other oxides such as titaniu and copper. Low-sulfide intrusive environments like the one in San Juan are common to contain laminated gold mineralization along quarz veins and as microcrystalline gold in the oxidized zones of the rhyolite or dacite. History: The project was the site of many small scale surface mining activities over the past century. Due to the easy surface access to the high-grade veins structures, many small adits and drift shafts cover the property. A larger adit and drift was believed to have been developed in the 1950's in Area 229. Several of the local prospectors have offered stories of high-grade production coming from this small operation. The main shaft was said to have later collapsed and operations ceased. Recent work: The property was later acquired by US Gold. In 2008 US Gold conducted a geological survey of the property, build an extensive access road network and conducted a large RAB drill program of up to 57 holes. In Sept 2008, US Gold announced 14 holes showing anomolous gold grades over a number of significant intervals. Shortly thereafter, amid the chaos of the economic collapse, US Gold issued a stop work order and dropped the San Juan project from their portfolio. It is important to note that the previous drilling by US Gold was rotary air blast (RAB) or blast hole drilling, which can be subject to sample smearing. As well, US Gold provided inaccurate GIS data on their hole locations. In the spring of 2011, a chip sampling and soil geochemical sampling program was conducted. In the fall of 2011, Leviathan conducted a limited chip sampling and GIS mapping program to begin due diligence and confirm the locations of the US gold drill holes.
