51° 31’ N lat., 90° W long. approx. 400 km northwest of Thunder Bay, Ontario, Canada.

The Property consists of a mix of contiguous patented and non-patented mining claims covering a total of 4,117 hectares (10,173 acres).  The core area encompassing the past producing Pickle Crow gold mine has dimensions of approximately 4 km SW-NE by 1.5 km SE-NW, and comprises 98 patented mining claims covering 1,532.9 hectares (3,788 acres).

PC Gold holds 100% of the Mining Lease encompassing the Pickle Crow Property, which expires July 31, 2067.  Registered ownership of mineral rights and surface rights is held by Teck Resources Limited.  PC Gold’s leasehold interest is additionally subject to two NSR Royalties totaling 1.25%, each of which it has the option of purchasing. 

Access & Infrastructure
Excellent.  Road and air access, power generators, 3 shafts, 2 winzes and some 40 kms (25 mi) of workings, 250 tpd mill, on-site office, tailings sites, mine dry facility, communications, water.  Nearby housing, educational, medical, recreational and shopping facilities, labour, industrial supplies and services.   

The past producing Pickle Crow gold mine was a long life (1935-1966), consistent money-maker.  Total production was 1.47 million oz gold (plus some silver) at 16.14 g/t Au (0.47 oz/T Au).  In the post WWII period the profits from the Pickle Crow mine partially underwrote the growth of Teck Corp.  The mine closed (1966) in a low gold price environment ($35/oz) with mineralization in place and multiple zones open to depth.  Dr. Norman B. Keevil was the President of PCGML at closing.

Previous Exploration
Extensive.  Between 1935 and 1966, mapping, geophysics, pitting, trenching, drilling etc.  Largely dormant 1966-1979.  Renewed activity and broad spectrum of work (geophysics, geochemistry, surface and underground drilling, misc. studies, etc.) in 1980s, esp. between 1985-1989.  Dormant for most of the 1990s.  Some drilling, bulk sampling, misc. environmental and metallurgical studies etc. and mill construction 1999-2005.

Previous Drilling
Estimated 3,635 surface and underground drill holes totaling 217,000 metres (711,900 ft.) between 1934 and 1999.

Regional and Local Geology
Located regionally within the Uchi subprovince of the Canadian Shield, the same belt of rocks that hosts the deep, rich mines of Red Lake.  Located locally within the Pickle Lake greenstone belt, a package of deformed, generally low-grade metavolcanics and metasediments with granitoid intrusions.  On the Property itself, principal rock types consist of metabasalts (greenstone) with intercalated metasediments, predominantly carbonate-magnetite banded iron formation, as well as quartz-feldspar porphyry and felsic to intermediate volcanic and volcaniclastic units.


Two principal styles have been identified:

  1. narrow, high-grade gold-bearing quartz-carbonate veins hosted in metamorphosed mafic lavas (greenstone) and porphyry, which were the main source of gold produced at the Pickle Crow Mine from 1935 to 1966; and

  2. iron formation hosted gold mineralization adjacent to vein structures. Only a limited amount of this second type of material was processed at the Pickle Crow Mine and most of it remains in place.   

Structural Controls
Gold mineralization at Pickle Crow (both quartz vein and iron formation hosted) has been localized along or adjacent to shear zones developed oblique to greenstone belt lithological trends and crossing between adjacent lithologically concordant shear zones or faults. 

Deposit Type
Archean low-sulphide Au-quartz veins.  Also known as shear-zone-hosted gold, Archean quartz-carbonate vein gold deposits, Archean lode gold and Archean mesothermal gold.  This category of gold deposit is found in every major Archean craton and accounts for worldwide historic gold production in excess of 9,900 tonnes of gold, second only to the Witwatersrand modified paleo-placer gold deposits of South Africa.

Mineral Resources
The Property hosts a National Instrument 43-101 ("NI 43-101") compliant inferred category mineral resource* totaling 10,150,000 tonnes averaging 3.9 g/t Au for 1.26 million ounces of contained gold (cut and diluted), comprising both potential underground and open pit mineable mineralization. The resource comprises 600,000 ounces in underground high grade veins averaging 9.3 g/t, cut and diluted, the same material the old timers mined, and 536,000 ounces in new, bulk mineable underground zones averaging 3.7 g/t, with an additional new 126,000 ounce open pit component, all of which remain open for expansion.    

The NI 43-101 resource estimate was prepared by Fladgate Exploration Consulting Corporation, and audited and approved by Micon International Limited under the direction of Mr. B. Terrence Hennessey, P.Geo., MAusIMM, Vice President of Micon, an independent Qualified Person as defined by NI 43-101. Mr. Neil Pettigrew, Vice President, Exploration for PC Gold and the Company's Qualified Person, is also a partner in Fladgate. The mineral resource is entirely classified as Inferred mineral resource. For full details see Company press releases dated April 18, 2011 and June 7, 2011, or download a full copy of the NI 43-101 technical report dated June 2, 2011 entitled: "A Mineral Resource Estimate for the Pickle Crow Property, Patricia Mining Division, Northwestern Ontario, Canada".

* Mineral resources that are not mineral reserves do not have demonstrated economic viability. The quantity and grade of reported inferred resources in this estimation are conceptual in nature and there has been insufficient exploration to define these inferred resources as an indicated or measured resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured resource category.


Studies indicate that in spite of the history of mining on the Property, water quality is generally very good to excellent, and historic activities are having no adverse effect.  Local populations of flora and fauna are healthy.  Moreover, tailings are benign in terms of acid rock drainage.  This is believed due to the presence of carbonate minerals in the ore historically mined and tailings that remain, which act to buffer any acid generated by oxidization of sulphide minerals, coupled with the fact that the sulphide content of the quartz vein ores historically mined was low, at generally less than 2%. 

Exploration Potential
The Pickle Crow gold mine produced a total of 1.47 million ounces of gold in its 31 years of operation between 1935 and 1966. The workings extend over 3 kilometres along strike of the core mine trend, and to a maximum depth of 1.2 kilometres.   The newly delivered initial compliant resource estimate suggests that, in addition to the ounces removed by past mining, at least another 1.26 million ounces of gold remain within approximately the top 1 kilometre of the core mine trend. Therefore, more than 2.5 million ounces of gold was originally hosted from surface to a depth of 1 kilometre within the core mine trend.

Deep drilling by the Company has confirmed the vertical continuity of the mineralized system below the historic workings. The historically top-producing (>500,000 ounce) No. 1 vein structure was intersected 210 metres below the lowest mined level on this vein, returning 134.26 g/t gold over 3.20 metres (3.92 oz/ton over 10.5 feet) from 1,139.80 metres to 1,143.00 metres in hole PC-09-052A, including 838.14 g/t gold over 0.50 metres (24.45 oz/ton over 1.6 feet) (press release, February 22, 2010). The Company later intercepted this same structure 680 metres below the lowest mined level on this vein (1,570 metres down hole) (press release, July 19, 2010).

The Company has also made several discoveries lateral to the historic workings. Most significantly, the No. 19 vein which returned 43.28 g/t gold over 13.13 metres (1.26 oz/ton over 43.1 feet) in hole PC-10-052-W02, including 138.89 g/t gold over 4.00 metres (4.05 oz/ton over 13.1 feet) (press release, March 23, 2010).

Results and discoveries such as these confirm that strong potential exists to increase the property’s mineral resource base through further exploration of areas lateral to and below the workings.


Current Work & Next Steps
The Company has recently demonstrated the presence in the mine of a 1.26 million ounce NI 43-101 compliant gold resource (see "Mineral Resources", above), the high grade underground component of which is 1.1 million ounces averaging 5.4 g/t, which the Company is presently focused on developing. As part of this development work, the Company has committed funds to complete, for anticipated delivery by summer’s end, a preliminary economic assessment ("PEA") and is in the process of arranging permitting to allow for dewatering and potential reconditioning of the 1.2 km deep shaft system at Pickle Crow, thereby enabling underground development of these high grade ounces. 

Going forward, drilling in the core mine trend will be driven largely off the results of the PEA, and will have both near surface and underground components, focused on in-fill drilling designed to lift inferred-level resources into higher confidence categories, resource expansion, and exploration for new zones.  

At present, surface based exploration drilling is continuing at the promising new near surface Central Pat East discovery, and targets elsewhere on the property, which offer significant resource expansion potential.  Modeling of zones such as Powderhouse, not presently included in the property's compliant resouce base, is also underway.
