Chester Township Property

Overview

The Chester Project is located in Ontario between Sudbury and Timmins just off highway 144. The town of Gogama is 20 km to the northeast. Geologically, the project sits at the southeastern tip of the SWAYZE Archean Greenstone Belt. It has also been interpreted to be a southwestern extension of the very productive Abitibi Greenstone Belt to the northwest. There is a Proterozoic cover of sediments which may be masking a possible link to this belt. Trelawney’s Chester Project is close to a major regional fault located just to the north of the project which appears to be a southwestern extension of the Cadillac-Larder Lake Fault Zone which runs through the Kirkland Lake area. The Destor Porcupine Fault Zone is a similar fault zone which runs through the gold deposits of the Timmins area. These large regional faults are in close proximity to some of Canada’s most productive gold camps with more than 68 Million ounces in the Timmins Camp and 42 million ounces in the Kirkland Lake district.

The Chester Project area occupies an 8 by 4 km portion of Chester Township. The area is underlain principally by a felsic to intermediate intrusive rock (granodiorite and diorite), with felsic to intermediate metavolcanics to the north and mafic intrusive rocks to the south.

The project area hosts at least 12 known gold mineralized structures. Trelawney’s initial focus was on three of these structures, namely the Chester 1, 2 and 3 Deposits. The Chester 1, 2 and 3 Deposits were historically known as the Murgold Chesbar, Young-Shannon and Jack Rabbit, respectively. Each hosts historical gold resources that have not been placed in production.

The Chester 1 hosts the No.3 vein which has been traced by a decline ramp for over 2,400 feet. It hosts a resource of 159,000 tons at 0.43 oz/t gold on the western part of the No. 3 vein.

The Chester 2 has limited workings down to 600 feet and hosts a resource of 222,000 tons at 0.354 oz/t gold in 2 parallel zones, C and C Prime.

The Chester 3 contains 3 mineralized Zones with a resource of 342,000 tons grading 0.36 oz/t for its No. 1 and No. 3 zones.

The following table provides a summary of the Historical Resource (non NI-43-101 compliant) for the 3 deposits. Including the inferred category, total resources for the three deposits down to a depth of only 600 feet amount to 1.7 million tons at 0.26 oz/t (or a quarter ounce) gold or nearly 470,000 ounces of gold (non NI-43-101 compliant).

Chester 1 Mine
The Chester 1 Mine includes a production-ready decline with a length of 5500 feet to a vertical depth of 500. There is 2300 feet of lateral development on five levels. The work on the development was completed between 1986 and 1989, but the mine was never in production. JS Redpath has estimated the replacement value at today’s cost for the underground to be in the order of $30-35 million. This has provided Trelawney with a 3-year lead on its development.

Drifting took place on ore with several raises up through the ore to test the continuity on the zones. There is also a step-out at the 150 level which confirmed the existence of mineralized parallel vein structures. The grades encountered through the ore raises and drifts were very typical of an Archean narrow quartz-sulphide gold-bearing vein. Grades range from 0.14 oz/t to 2 oz/t gold. The raise below the Bates shaft for example returned a grade of 1.13 oz/t over 4.8 ft for 84 feet.

To confirm the grades and the continuity or the ore, Watts Griffith McOuat carried out a channel sampling program on 3-metre centres from the top of the portal, down the ramp and all the way through all of the ore drives. James Wade Engineering carried out the same program 1 foot away from the original trench samples and the grades came back within points of each other. Trelawney is confident that the duplication of the results in these programs provides confirmation for the overall 0.43 opt for the Chester 1 mine.

Rather than twinning the historic holes in the underground development, Trelawney drilled 4 holes up to 1000 feet below the know extent of mineralization and mine workings. We wanted to check the down-dip extension of the mineralized structure. We hit the zone at 1000 vertical feet and our drill holes actually graded with assays ranging from 3.26 g/t to 36.67 g/t gold. Drill hole CM09-02 hit another parallel zone in the hanging wall which ran 54 g/t gold.

Once Trelawney secured the Chester 1 property, it looked at the neighbouring property to the west (The Chester 2) with its historic resources. Trelawney plans to drive a haulage drift 1 km to the west to the Chester 2 C and C’ zones which would provide an additional resource of 220,000 tons of 0.36 oz/t gold (non NI-43-101 compliant). This would increase daily throughput of ore from 250 tpd at Chester 1 to 500 tpd with Chester 2 in 12 months time. Projected gold production would increase from 33,000 to 66,000 oz per year after 24 months.

In early February Trelawney purchased the equipment and plant required to establish the mine infrastructure at the Chester 1 Mine. The material included surface and underground electrical distribution system, ventilation and mine air heat system, compressors furnished warehouse, work shop, offices and various pieces of mobile equipment. Over 40 semi truck loads were transported to the Chester Mine Site from Quebec.

A Dewatering Permit was granted for the Chester Mine in February.

We are currently in the final stages of receiving the advanced exploration permit which will allow us to refurbish the underground and take our first bulk sample.

Exploration – Cote Lake Deposit

While advancing the development on the Chester 1 mine, Trelawney continues its exploration efforts to the southwest of the Chester 2 zone (Cote Lake area). Ground IP and Mag surveys were undertaken in this area. Drilling took place on series of drill fences starting with line 93+00 and subsequent 100-metre step-out fences.

Trelawney’s first drill hole E09-01 intersected 136 metres of 1.16 g/t Au including 90.51 g/t Au over 1.00 metres.

An overcut hole E09-02 did not hit mineralization and the drill rig was turned to face grid south (150º Az). The 3 subsequent holes 03, 04, and 05 all hit wide widths of mineralization including 107.11 metres of 8.20 g/t Au including 313.55 g/t Au over 2.56 metres in hole 04 and 178.8 metres of 1.45 g/t Au in hole 05.

On a 100-metre step out to the east at Line 94, Trelawney intersected more wide mineralized intervals. A highlight from this section includes 190.7 metres of 1.88 g/t Au in hole 09.

Drilling continues to uncover wide zones of low to moderate grade gold +/- copper mineralization which are associated with brecciated intermediate to felsic, and locally mafic intrusive rocks. Mineralization occurs in the form of disseminated and fracture controlled sulfides which generally correlate to the gold values. Visible gold is commonly observed. The zones are bleached with the prevalent alteration being feldspathic and chloritic and biotitic. The mineralization and alteration envelope associated with this system remains open in both directions along strike and to depth. Drilling highlights on this new large tonnage gold target include: 107 metres of 8.2 g/t gold (hole E10-04), 191 metres of 1.88 g/t gold (E10-09), 292 metres of 0.88 g/t gold (E10-26), and 137 metres of 5.33 g/t gold (E10-27). Average grades range from 1-2 g/t gold over intervals of up to and locally greater than 200 metres. 

To date Trelawney has drilled 43 holes totaling over 18,000 metres on the Cote Lake Deposit. Results for 31 of these holes have been reported this year in press releases.  Mineralization at Cote Lake has now been intersected on seven sections spaced 100 metres apart (90E to 96E) and traced to depths of up to 500 metres. Mineralization is open both along strike and to depth on all sections.

The expansion and exploration drill program continues with two rigs defining the extent of the Cote Lake deposit and a third rig exploring other targets on the 1,700 hectare (4,200 acre) Chester Property.
