Orex Exploration

[5] Orex's Goldboro main property consisted of 37 contiguous claims (600 hectares) held under license from the Province of Nova Scotia.

[6] The main project location is found at Latitude: 45° 10´ North ; Longitude: 61° 40´ West (NTS 11F/04) On November 26, 2009, following a joint venture agreement with Osisko Mining, Orex staked hundreds of additional contiguous claims which cover 960.8 square kilometers surrounding the Goldboro strike area.

On November 1, 2010 Orex reported that Osisko had incurred exploration and development expenditures in excess of the $1,500,000 minimum required by September 29, 2010.

Osisko stated "While the results from the 2010 and 2011 drilling campaigns are encouraging, they indicate the presence of a smaller deposit potentially minable by selective underground methods focussed on the veins, or alternatively a relatively shallow open pit operation, both of which are outside the scope of Osisko's exploration and acquisition strategy.

This information was officially revealed on November 30, 2010, although it had long been understood to be occurring by local residents and people close to the project.

The company also reported a float sample grading 0.121 g/t in an area close to the Stillwater anticline with historic anomalous gold occurrences.

The property is entirely underlain by sedimentary rocks of the Goldenville Group, which consist of altered greywacke, sandstone (arenite), and slate.

In Nova Scotia, the Boston-Richardson mine (Upper Seal Harbour district) is a classic example of a “saddle reef” deposit.

The gold mineralization at Goldboro occurs in association with and within a quartz vein swarm located in the hinges of regional anticlines, principally in black shale-argillite wall rocks.

Exploration by Orex from 2005-2008 indicated that in certain portions of the sedimentary sequence the intervening sandstone rocks contained sufficient veining and mineralization that in combination with the shale/slate units formed large zones of lower grades that could possibly be mined by open pit methods.

The shorter term focus has been the identification and delineation of the maximum number of low cost near surface potentially open pit resources.

Faribault mapped Nova Scotia's gold fields for the Geological Survey Department (Government of Canada).

He focused on the intricate folds in the gold-bearing formations along the southeast coast of Nova Scotia known as the Meguma Group.

In addition detailed cross sections of the Isaac's Harbour gold district and also of the Boston Richardson mine were produced by Faribault (below).

Historically, the severe “nugget effect” produced by the extreme variability in gold size and distribution within the Goldboro mineralized belts forced companies to implement a number of sampling and grade determination programs.

The Australian examples demonstrate that narrow quartz vein gold deposits, similar to those in Nova Scotia, can be mined profitably.

In 1956 The Canso Mining Corporation dewatered the Locarno shaft and did some basic exploration but work was stopped due to financial difficulty.

The East Goldbrook shaft was dewatered between 1931 and 1934 by Renada Mines Ltd. who sampled the workings and assaying gave results between 1.61 and 4.26 g/t Au.

In 1988 a surface and underground exploration program was undertaken to cover the property to the west of the Boston Richardson Mine.

The Pre-Feasibility study recommended underground mining, a standard gravity/flotation mill and concluded that a profit of $40 per ton would be realized.

[54] The company then notified the Department of the Environment for the Province of Nova Scotia of its intent to proceed with a Gold Mining Project.

A public meeting was held as part of this process on March 27, 1989 with the major concerns being the environmental control requirements from the government, possible stream contamination and site reclamation.

Between 1990 and 1993 very little exploration work occurred on the property while a scientific debate raged about the correct way to accurate measure the gold deposit's grade and numerous technical reports and assessments were completed.

Placer Dome contacted Orex in 1995 and offered to assist as they had encountered similar sampling problems in the past.

Due to budget cutbacks, conventional sampling was reinstated with a return to the previous "low grade" results.

In February 2004, MRB & Associates was retained by Orex to prepare an independent technical report on the Goldboro property.

Another purpose was to review historical sampling and analytical grade determination procedures at Goldboro and provide an assessment of the data quality and suitability of these historical results as they pertain to: The conclusions and recommendations stemming from the study set the stage for the 2005 exploration program undertaken by Orex, specifically the conclusions regarding grade determinations.

The proposed pattern of drilling and number of holes was designed to allow two (2) separate shallow areas to be similarly tested.

In 2006 P&E Mining consultants was commissioned to produce a new NI43-101 compliant Resource estimate based on the results from the new 2005 drilling campaign.
