(Darien) holds title to 3 claims located in Long Township south ofElliot Lake and approximately 1 km north of Lake Lauzon. The claims are underlain by the Huronian Supergroup and post-Huronian gabbroic rocks which have been mapped and interpreted by previous workers as Nipissing Diabase. Darien is in the process of evaluating the potential of the Nipissing Diabase to host a high quality aggregate resource. As part of this assessment, Darien completed a program of drilling, blasting, trenching, and removal of an approximately 68 tonne bulk sample. The bulk sample is being prepared for sub-sampling and physical properties testing. PROPERTY, LOCATION, ACCESS, AND TOPOGRAPHY The property is located approximately 140 km west-southwest of Sudbury, at 83° W and 46° N adjacent to the north shore of Lake Huron (Figure 1). The property is located north of Highway 17 and is accessed via a trappers trail originating from the end of Pronto Road. The property is also accessed by boat travel to the north shore of Lake Lauzon and then bush traverse for approximately 1 kilomtre (Figure 2) The topography ofthe area is variable from relatively flat lying, gentle relief in the area of highway 17 and the north shore of Lake Huron where the elevation is approximately 180 metres ASL to relatively rugged and a maximum elevation of approximately 300 metres ASL on the claim block .. The topography is controlled by bed rock features and the Nipissing Diabase forms topographic highs with locally steep scarps into lakes and drainages. The property comprises 3 claims located in Long Townships within the Sault St. Marie Mining division (Table 1). All ofthe claims are 100% owned by Darien Resources Inc. PREVIOUS WORK The geology of Long Township has been mapped by James A. Robertson and was published in 1970 (Robertson, 1970). This, and adjacent reports by Rpbertson (Robertson, 1964), form a comprehensive description of the bedrock geology including the Nipissing Diabase. In 1996, the Ontario Geological Survey completed and published a study on the assessment of the industrial mineral potential of the Nipissing Diabase in a corridor from Massey to Blind River and including the North Channel Islands (Ontario Geological Survey, 1996). This study considered two sites in the area of the Darien property- one site approximately 1.5 kilometres east of the Darien property (SRA-4) and one site approximately 3 kilomteres west of the Darien claims (SRA- j \ ~/' ~~~ <b - ) !

Physical property tests completed on the sample taken from site SRA-4 indicate that the diabase at this site has a range of applications including high quality aggregate to be used in asphalt paving. The study estimates a potential resource of 40 million tonnes at SRA-4. No sample was taken at SRA-4 Extension. However, the continuity of the diabase from SRA-4 to SRA-4 Extension was noted and a potential resource tonnage of> 300 million tonnes was estimated for this site. The area of the Darien claims has been explored both for Uranium potentially hosted by the Huronian sedimentary rocks and for Copper potentially hosted by the Nipissing diabase. No sulphide occurrences have been documented on the property in the provincial mineral deposit inventory (Ontario Geological Survey, 2004). Darien Resources Inc. has completed geological mapping and sampling on claims covering the same parts of the diabase as the current claims. The previous claims expired and the current claims were staked and recorded on June 8, 2007 (claims 4223995 and 4219196) and November 25, 2009 (claim 3009531 ). The work on the previous claims is described in assessment reports filed by Darien. Previous work by Darien has determined that a sample of the Diabase in the area of claims 4219196 and 4223995 is suitable for use as aggregate in HLI and DFC asphalt pavements. Furthermore, previous work by Darien has determined the chemical composition of this sample and that it is comparable to the whole rock chemical composition ofNippissing Diabase at Bruce Mines where the diabase is quarried and is listed on the 'Designated Source for Materials' list by MTO. In October 2009, Darien reported work on claims 4223995 and 4219196 that included mapping, sampling, chemical analyses, and petrography. The results ofthis work supported previous work by Darien that the claims hold the potential to host a high quality diabase aggregate resource. REGIONAL AND PROPERTY GEOLOGY The property is located within the Southern Structural Province of the Canadian Shield which, in general terms, consists of an Archean basement overlain by the Early Proterozoic Huronian Supergroup and intruded by a number of felsic to mafic intrusive bodies that range in age from Early to Middle Proterozoic (Figure 3). The Archean rocks exposed on the property consist dominantly of massive to gneissic granitic rocks. Huronian rocks present on the property include the Lower and Middle Mississagi Formations (feldspathic quartzite, arkose and greywacke, siltsone, argillite respectively) and the Gowganda Formation (interbedded conglomerate, feldspathic quartzite, argillite, and siltstone). The southeastern part of the property includes mafic metavocanic rocks and related chloritic sedimentary rocks. Both the Archean granitic rocks and the Huronian sedimentary rocks are intruded by mafic intrusive rocks referred to as Nipissing Diabase (e.g. Robertson, 1970).

The dykes consist of dominantly of diabase, gabbro, and diorite. They are interpreted to have intruded during the Hudsonian Orogeny at approximately 2.15 Ga. (Robertson, 1970). NIPISSING DIABASE The Darien claims cover a part of a Nipissing intrusive body that trends approximately east-west over approximately 2 km of strike length and is located approximately 1-5 kilometres north of Lake Lauzon (Figure 3). On the Darien claims the dyke has a thickness that ranges from 150 metres to 450 metres. Previous mapping indicates

  • Land, Natural Resources, and Geology
    Land and Natural Resources of West Amwell By Fred Bowers, Ph.D Goat Hill from the north Diabase Boulders are common. Shale and Argillite outcrops appear like this. General Description of the Area West Amwell Township is in Hunterdon County, New Jersey, USA. It is a 22 square mile rural township with just over 2200 people, located near Lambertville, New Jersey. It is one of the more scenic parts of the New Jersey Piedmont. It is identified in red on the maps below. West Amwell is characterized by most people as a "rocky land." One of the oldest villages in the township is called Rocktown. If you visit or look around the township, you cannot avoid seeing rocks and outcrops like those pictured above. Hunterdon County New Jersey, with West Amwell located at the southern border, marked in red The physiographic provinces of New Jersey, with Hunterdon County and West Amwell marked in red Rocks The backbone of West Amwell Township's land is the Sourland Mountain; a typical Piedmont ridge formed by a very hard igneous rock called diabase or "Trap Rock." The Sourland Mountain ends at the Delaware River below Goat Hill which you see in the picture above, looking south from the Lambertville toll bridge. To the south and north of the diabase, shale and argillite occurs, and these rocks form the lower lands we know of as Pleasant Valley and the shale ridges and valleys you see from around Mt. Airy. In order to appreciate the rocks and the influence they have on the look of the land, it is useful to have a short review of rocks.

Its Late Permian–Middle Triassic section includes basaltic stratum-like bodies, sills, formed at 250–248 Ma. The basalts are medium-high-Ti tholeiites enriched in La. Compositionally they are close to the Early Triassic basalts of the Syverma Formation in the Siberian Flood basalt large igneous province, basalts of the Urengoi Rift in the West Siberian Basin and to the Triassic basalts of the North-Mongolian rift system. The basalts probably formed in relation to mantle plume activity: they are enriched in light rare-earth elements (LREE; Lan = 90–115, La/Smn = 2.4–2.6) but relatively depleted in Nb (Nb/Labse = 0.34–0.48). Low to medium differentiation of heavy rare-earth elements (HREE; Gd/Ybn = 1.4–1.7) suggests a spinel facies mantle source for basaltic melts.

Instead, rocks in some parts of the lower crust and/or upper mantle need to melt in order to make magma. Once magma forms, it will try to rise from higher-pressure regions (deeper in the crust) to lower pressure areas (near Earth’s surface) because magma is less dense than solid rock. As magma rises, it cools. Most often, it cools and hardens (the magma crystallizes, meaning that crystals [minerals] form) before it makes it to the surface. But sometimes magma will migrate all the way to Earth’s surface and erupt in a volcano. Once it erupts, the magma is called lava.

The north­ west limb of the syncline dips 10-~0 0 S.E. toward Lake Superior and is dominated by the Duluth Gabbro Complex, a huge sill-like mass with crescentic outcrop that extends almost 150 miles from Duluth to near Hovland. At Duluth the gabbro complex lies on the Thomson Formation, and apparently was intruded along the surface of unconformity below the Keweenawan rocks. The gabbro complex was formed by multiple intrusion, and consists of an older anorthositic gabbro and a younger layered gabbro and related intrusions. Keweenawan flows above the gab­ bro mass are cut by diabase sills. The basalt flows at one locality currently are being quarried as a source of crushed rock for concrete aggregate.
