Jet Gold Corp has the option to acquire 100% interest in the Big Hammer gold-silver-tellurium (Au-Ag-Te) discovery near Terrace, British Columbia. Big Hammer covers the lower slopes of Thornhill Mountain and Mt. Attree on the north side of Williams Creek, 13 kilometers southeast of Terrace. The property consists of six tenures which have a total area of 1,617 hectares (3,996 acres). Road access to the property is all season and year round work is feasible.
Big Hammer occurs along the western margin of the Intermontane Belt, adjacent to the Coast Crystaline Belt. Basement rocks include Carboniferous intrusive and which include the andesites, basalt breccias, and basalt flows of the Mt. Attree Volcanics. The basement rocks are intruded by Late Jurassic granodiorite and granite of the Kleanza pluton and the non-foliated Eocene granite of the Williams Creek Pluton. The mineralization occurs within in a late Carboniferous, Mississippian intrusive unit which is foliated diorite, granodiorite, tonalite and metagabbro.
Big Hammer's Au-Ag-Te mineralization was first discovered on new logging road cuts in 2007 within a thick series of sheeted, low-angle quartz-pyrite veins. Host rocks are Carboniferous granitics and possibly altered basement volcanics. The multiple Big Hammer Au-Ag-Te showings are also anomalous in lead (Pb), copper (Cu), zinc (Zn), cobalt (Co) and tungsten (W).
The most significant assays have so far been in the 380 vein (380 m elevation), with one meter thicknesses assaying up to 26.2 ppm Au (0.77 opt Au), 264 ppm Ag (7.77 opt Au) and 100 ppm Te. The best grab samples from this vein returned 50.2 ppm gold (1.48 opt), 522 ppm silver (15.4 opt) and 451 ppm Te.
The 625 zone (625 m elevation) is a group of five veins in a zone approximately 40 meters thick, and is also worth mentioning. The thickest of the 625 veins is two meters thick and has returned values of up to 14.6 ppm gold (0.42 opt) and 19 ppm tellurium. Another vein within this group, the 615 vein (30 cm), assays up to 1,900 ppm W. The 700 vein (also 30 cm) yielded 0.19 ppm Au, 361 ppm Co, 0.2% Cu and 748 ppm Zn.
A sulphidic zone at 800 meters elevation that is approximately 5m thick, with similar geometry to the 380 and 625 veins. Silver and also cobalt, cesium, rhenium, and selenium are anomalous in the 800 vein.
Work to date on the Big Hammer property is limited to road-cut sampling and limited outcrops. The significant (>1,000 m horizontal and >300 m vertical) extent of the known Big Hammer mineralization suggests additional veins will be found with mapping, surface trenching and diamond drilling.
INTRODUCTION
The Big Hammer Au-Ag-Te property is situated on the southwest flanks of Thornhill Mountain and Mt. Attree near Terrace, British Columbia. Numerous Au, Ag, Pb, W, Cu, Zn, and Mo prospects were worked over much of Thornhill Mountain since the early part of the 20th century. The most prominent of these are:
- Beaver-Lucky Seven (MINFILE 103I 099) which produced 6,221 gm Au (182 oz Au) from 91 tonnes of ore.
- Golden Nib (MINFILE 103I 095) which produced 1,493 gm Au (44 oz Au), 1,275 gm Ag, and 302 kg Cu from 27 tonnes of ore.
The Big Hammer prospect includes a historic showing (The Coin), but a new Au-Te discovery has been made in an area with no recorded previous work. The work summarized herein was completed by Doug McRae. Samples collected on the property were either collected by the author or by geologists visiting the property who have no affiliation with the author. For continuity assay results are presented in parts per million (ppm) with the convention that 1 ppm = 1 gram (gm) and 34 gm = 1 ounce.
LOCATION, ACCESS and PHYSIGRAPHY
Big Hammer is located is located 13 kilometers (eight miles) southeast of the city of Terrace, British Columbia. The property is accessed by 15 kilometers (9 miles) of paved public road from Terrace. The sampled road cuts are 3.5 kilometers (two miles) from pavement on a logging road, the Branch P67219. An alternate route to the main highway (Highway 37 South) to the Port of Kitimat is approximately five kilometers (three miles) via Old Lakelse Lake Drive. Road access to the property is all season.
General Location
The property is located on the lower slopes of a massif formed by Copper Mountain, Thornhill Mountain and Mt. Attree, on the north side of Williams Creek. This massif forms part of a physiographic area described as the Coast Mountain Range. Elevation ranges from 135m to 1,550m with the main showings being at 380m and 625m. The lower elevations of the property are covered by alluvial gravels and glacial till, the mid portions are covered by shallow till and the upper portion is alpine. Rock outcrop is common and good exposures can be observed in multiple switch backs of the logging road and in root wads of overturned trees.
Steep, narrow ravines with year-round flow traverse the central portion of the property. The streams within the property are juvenile. The main un-named creeks are steep with little bed load and apparently occupy joints and fractures within the bedrock. For the purposes of this report and future work on the property, these creeks have been designated 1km, 2 km and 3 km Creeks based on the location at which they cross the Williams Creek logging road.
The Big Hammer
The bulk of the property has been logged within the past 15 years and as recently as 2006. The ground that has not been logged is covered with first growth hemlock, balsam, pine, spruce and cedar. Under-story is typically huckleberry, false azalea and suppressed conifers. A recent "blow down" toppled some of the remaining trees, some of which can make access difficult in the affected areas.
CLAIM OWNERSHIP
The property consists of six tenures which have a total area of 1,617 hectares (3,996 acres). These tenures are under option to Jet Gold Corp who can earn 100% interest from of Douglas R McRae who is the registered owner. Tenures 575019 and 586469 are in good standing until 2011/01/30, 593572 is in good standing until 2010/09/30, 599421 is in good standing until 2010/09/30 and 646524 and 646525 are in good standing until 2010/10/03.

REGIONAL GEOLOGY
The Big Hammer property is within the Chist Creek Map Area of Nelson, Kyba, McKeown and Angen (2008) and the Terrace Map Area of Duffell and Souther (1964). The property lies along the western margin of the Intermontane Geomorphological Belt, adjacent to the Coast Crystalline Belt. The Terrane on the eastern portion of the property is mapped as Stikine while on the west it is mapped a Post Accretional.
A belt of Carboniferous andesite and basalt breccias and flows of the Mt Attree volcanics (ca. 330 Ma), are intruded by a Mississippian intrusion (ca. 323 Ma) and the Late Jurassic Kleanza (ca. 200 Ma) and the Eocene Williams Creek (ca. 53 Ma) plutons. The Lower Jurassic Telkwa volcanic suite (ca. 194-200 Ma) joins from the east to form the Copper Mountain, Thornhill Mountain and Mt. Attree massif.
The late Carboniferous, Mississippian unit is foliated diorite, granodiorite, tonalite and metagabbro. The Kleanza Pluton is equigranular granodiorite and granite while the Williams Creek Pluton is mainly granite. A Pre-Permian sedimentary suite (ca. 330-317 Ma) outcrops sporadically on the massif as well as to the south on Mount Layton.
The large bodies of Jurassic and Eocene intrusive rocks were likely formed at depths of several kilometres. Partial erosion has exposed them, along with roof pendants of the older volcanic and sedimentary rocks, on Copper, Thornhill, Attree and Layton mountains. These intrusive rocks also outcrop within the graben of the Kitimat Trench along Old Lakelse Drive and farther south toward Kitimat. The Kitimat Trench is some 180 km long and is 12 km wide adjacent to the Copper-Attree massif, with an apparent vertical displacement of 1,400 meters.
The vertical displacement of the Kitimat trench has exposed exfoliation joints/fractures within the Kleanza and Williams creek plutons. The erosion of these exfoliation joints produced distinct flat iron features. At the north ends of Copper Mountain and Mt. Layton, well-developed fractures sets within the plutons strike generally north and dip 850 west to northwest. The strike of these joints varies as jointing is crescent shaped ranging from approximately 00 on Copper Mountain to 300 on Mt. Layton. Evidence of the joints is also visible on the mid slope of Thornhill Mountain where the attitude of the joints has protected them from erosion.
North end of Copper Mtn.
A strong series of northwest-striking parallel fractures (3300 to 3400) control the topographic features in the area that follow the general trend of British Columbia. The strike of the Williams Creek is an excellent example of this as are fractures noted on Mt. Layton and the Copper -- Attree massif.

PROPERTY GEOLOGY
Granodiorite, diorite, quartz diorite and granite of the Kleanza and Williams Creek plutons have intruded and contain localized remnants of Carboniferous granite, andesite and basalt breccias and flows and abut and intrude the Lower Jurassic Telkwa volcanic suit to the east. Volcanic dykes of andesite, dacite, rhyolite and lamphyre have intruded the granitic rocks.
Age relationship between the granitic rocks is uncertain and some classification has been undertaken by Nelson et al in postulating rock ages. This dating has the Williams Creek pluton intruding the older Kleanza pluton some 50 MA. The University of British Columbia rock age data available for the area is not specific to the property area but is relevant in general. This data returned values of for the Kleanza Pluton of 200 Ma (sample 12776) while samples of younger intrusions have returned values of 21 Ma (sample 12907) and 65 Ma (sample 12235). The Telkwa Volcanic Group is dated at 193 Ma to 195 Ma based on samples 12277 and 12278. New rock age data provided by; J. Nelson, R. Friedman and G. Pignotta, unpublished data 2010, changes portions previously mapped as 50 ma Eocene Williams Creek Pluton, to a Mississippian intrusion with an estimated age of 323 Ma. (J. Nelson, R. Friedman and G. Pignotta, unpublished data 2010).
QUARTZ VEINS
The quartz veins are white to pale gray and often smoky grey. They can be translucent and glassy to granular quartz. Terminated, subhedral quartzs crystals can be found with vugs within veins. Iron oxide coats the fracture surfaces. The quartz veins appear within a thick series as low angle sheets within parallel fractures. Vein material is cohesive to the wall rock. Suphides are often concentrated near vein margins with pyrite being the most abundant sulphide. Some yellowish oxides are noted coating a quartz vein in the 625 zone which is attributed to the high tungsten (W) values in the vein.
STRUCTURE
Mapping of the surface traces within and adjacent to the Big Hammer property using Google Earth and Auto Cad Map 3d has contributed to an understanding of structure. Apparent features were traced and color coded to designate possible commonality as well as mapped features were modeled for comparisons. Time of day manipulation was used to highlight fractures and jointing. The results of this mapping are preliminary but where possible has been verified by field observation and review of adjacent property reports.
Within the property, the dip of the primarily northerly joint/fracture set described in the Regional Geology appears to be reduced with estimated joint dip angle of 300 to 450. Three well defined drainages (1 km, 2 km and 3 km Creeks) are developed along 3 of these northerly trending fractures. A secondary fracture set within the Big Hammer property has a surface trace that generally trends northwest (approximately 3000 to 3100). A less coherent but potentially important tertiary fracture set strikes generally 900 but is more variable.

Typical fractures occupied by veins (625 Zone)
ALTERATION
Silicification of the granitic and volcanic rocks at the Big Hammer occurs along shallow dipping fractures and in thin veinlets. Epidote alteration appears regularly within the granitic rocks typically hydrothermal alteration of the feldspars in the granites. Bands of epidote can be up to 2m wide. Chloritization of the granite is also common.
MINERALIZATION
To date, the Big Hammer's high-grade Au-Ag mineralization is associated or hosted by the Mississippian foliated granite and granodiorite. Northerly striking joint / fracture trends, including 1 km, 2km and 3 km creeks, extending south from the Kleanza Pluton to the Mississippian foliated granite seem to control much of the mineralization on the Big Hammer property. The apparent rotation in structural attitude of this proliferating fracture set at the Big Hammer may offer an intriguing structural exploration target.
A tertiary fracture set with a strike of 0900 and a dip of 200 to 250 N has been observed within the property and appears to be significant to Au mineralization found at the 380 vein, 625 Zone and 700 vein. Mineralized quartz-pyrite veins with silicified hanging and foot walls occupy these fractures. (Figure 4 TBA)
New mineralization was found in 2010 at 2 km Creek above the logging road bridge. It is within a contact zone of intrusive and volcanic rocks which show good sulphidic and silicious alteration. This mineralization lies along a roughly common joint with the 800 Vein. Strike of the fracture within the creek is estimated as north easterly with the dip being approximately 800 west.
Mineralization occurs within a milky white, banded, quartz-pyrite veins which are typically cohesive to the head and foot wall parent material. Some vuggy texture is noted in the quartz. The mineralization is typically lustrous and silver colored with smoky black sulfides which may be silver sulfosalts and/or tellurides. No visible gold has been observed. The vein hosting fractures sets have a strike of 090 degrees and a dip estimated to be 20 to 25 degrees north. Host material is fine grain foliated older intrusive and the dark iron staining of the quartz veins has been key to identifying them in the field.
Gold, silver and tellurium are the primary targets for this property. The tellurium was found by chance as a full suite geochemical analysis was completed on several samples. To date it is has not typically been assayed for in this area. Many of the assays for the property did not test for tellurium and in future it will be included in all testing. A 4 acid digest test is recommended for total tellurium return. Values of elements stated in this report vary by location as well as analytical methods. Arsenic is noted by it's absence. To date none of the assays have returned arsenic values over 5.8 ppm.

Selenium ranges from 13.3 ppm to 32.9 ppm.
800m Vein
Coin
The Coin is a quartz vein in granodiorite located at approximately 250m elevation. It's reported geometry is significant as it is similar to the 380, 445, 480, 625 and 700 veins. The more northern gold showings, the Lucky Seven, Society Girl and the Golden Nib vary from this geometry with their strike typically being in order of 50 to 60 degrees azimuth and dips to the southeast at much steep angles, 40-70 degrees. The Coin lies within tenure 599421. (Figure 5 and 6B)
The Coin adit has not been found to date but a bull quartz vein and mineralized float has been found. Kindle reported the vein at 244m elevation with a dip of 30 degrees northeast and a strike of 80 degrees azimuth. He observed the vein having an average width of 0.35m over 24m and that a 6m adit had been driven mid way on the exposure. At the face of the adit, the vein had altered over a width of 1m. Kindle's reported assays range from 0.01 to 0.02 ounce per ton gold and 0.06 to 1.04 ounces per ton silver. MINFILE 103 101 reports a 51 cm channel sample returned 0.7 ppm gold and 9.3 ppm silver which is likely the conversion of Kindle's reported values. (ARIS report 13104 - Allen, 1984)
Quartz float from the approximate area collected in 2009 (G073046) returned 3.87 ppm silver and 4.39 ppm tellurium. A sample of apparently barren quartz vein returned an anomalous cerium value of 13.75 ppm and a tellurium value of 0.98 ppm.
TELLURIUM
Tellurium is one of the rarest elements found on earth and is a significant and relatively new semiconductor. It is used in a wide range of uses with medical, solar cell, metallurgical and computer memory applications. Cadmium telluride solar panels have achieved some of the highest efficiencies for solar power generation. Tellurium sub-oxide is used in several types of rewritable optical discs. Much of this new technology Blu-Ray discs, for example are critically dependant on tellurium.
Tellurium is usually found as the telluride of gold (calaverite - AuTe2), and combined with other metals. Tellurium compounds are the most common chemical compounds of gold found in nature (rare non-tellurides such as gold aurostbite and bismuthide are known). Tellurium is also found combined with elements other than gold, in salts of other metals.
The principal source of tellurium, > 80%, is from anode sludges produced during the electrolytic refining of blister copper. It is also a component of dusts from blast furnace refining of lead. It requires approximately 500 tons of copper ore to typically yield one pound (0.45 kg) of tellurium. Annual global production is estimated to be between 170 to 500 tons but these numbers are vague as many producers do not report. World production by country can be thus be roughly estimated by copper refining capacity. Extraction via copper refining is inefficient with approximately only 1/3 of the tellurium being extracted with current technology. As a significant cost would be incurred to upgrade plants, copper producers are unlikely to upgrade.
The solar cell manufacturers have the highest demand for tellurium and will soon be competing with the non-solar industries driving the cost up and the availability down. In 2004, tellurium was $10/lb USD. By 2005 it was up to $180/lb and settled back to $75/lb by 2007. Values for 2010 have been estimated in order of $200/lb USD.
Average crustal values of tellurium are less than 0.002 ppm which makes it one of the 9 rarest elements on earth. Values over 10 ppm are important and values over 50 ppm are significant. Values over 100 ppm, are moving towards ore grade dependant on association with gold and silver. One of the richest gold/tellurium mines in the world, La Bombina in Mexico, has tellurium values in the order of 1,000 to 1,500 ppm.
The tellurium values found to date on the Big Hammer, up to 451 ppm, are promising and better values can be expected at depth. Telluride minerals are easily destroyed by weathering and the current mineralized outcrops have been exposed for close to 15 years.
DEPOSIT ANALOGS
In this early stage of exploration a deposit model is difficult to define and several deposit analogs have been researched for the project. One model that is most interesting is the RIRGS (Reduced Intrusion-Related Gold System) with Fort Knox and Dublin Gulch as analogs. These are typified by low sulphide, sheeted quartz veins with Au-Bi-Te-W relationships. This type of deposit is formed within a region of hydrothermal influence surrounding the causative pluton. Plutons that generate RIRGS form in tectonic settings characterized by weak post-collisional extension behind a thickened continental margin.
(Reduced Intrusion-Related Gold Systems, Hart 2007)
On the face of it, the Big Hammer easily fits within this model style but significant work is required to define the property. Given the complexity and variety of gold deposit models, it also may just be "Big Hammer" style.
HISTORY
The main showings on the Big Hammer are new discoveries. Significant work has been done historically to the north of the property and it is likely prospecting took place in and along the streams within the property in the past. The construction of the logging road through the property led to the discovery.
The 380 vein was discovered in 2007 by Jeff Kyba while working on a mapping project for of the BC Geologic Survey, under the supervision of JoAnne Nelson. Jeff observed mineralized float in the ditch which led him to the vein. Jeff also discovered a sulphide zone at 800m elevation and approximately 800m north of the 700 vein which returned some silver values. This work was reported in 2008 in; Geology of the Chist Creek map area NTS 103I/08, British Columbia: BC Ministry of Energy, Mines and Petroleum Resources Open File 2008-3.
Doug McRae staked the showing following the data release. Samples were collected by Doug McRae and analyzed, which confirmed the reported discovery.
The 625 zone and the 700 Vein were discovered by Doug McRae and Don Strachan of World Industrial Minerals while reviewing the 380 vein for tellurium potential.
RECOMMENDED EXPLORATION
Given the excellent exposure provided by the logging roads within the property, a basic exploration program is warranted. This will include mapping the exposed outcrop along the existing skid trails, roads and bounding creek gullies. Machine and hand trenching of the existing and any new showings should follow the mapping phase. Priority for trenching should be given to the 380 vein and the 625 zone to extend the strike length of the showings. As well, the entire 625 zone should have the ditch line cleaned to fully expose the mineralization.
Existing road and cut block provide excellent bedrock exposure
Drilling could be completed at any time as there are no trails or drill pads to construct. Water for drilling is easily accessible and is within 1500m from any proposed hole. Water is closer but is seasonal and hose runs can be laid on the road or within the cut block. The access road will require some work with a excavator and dump truck and an existing bridge will require temporary deck panels as the running surface is rotten.
No mechanical exploration is planned on the Coin showing at this time. Prospecting and mapping will be completed in this area as well as within rest of the tenures. Tenure 593572 and 646525 will be reviewed with the long term goal of reducing land base as required.
