1.0 INTRODUCTION
Mosquito Consolidated Gold Mines, Ltd. (Mosquito) will be conducting a variety of mineralexploration activities under the Plan of Operations (PoO) anticipated to be approved by theBoise National Forest Supervisor in June, 2011 for the CuMo project. As part of its approvedexploration activities, Mosquito will construct new drill pads and temporary roads. Under themitigation requirements of the Environmental Assessment (EA) (USDA, 2011) prepared for thisproject, the United States Forest Service (USFS) requires that Mosquito reclaiby its exploration activities as well as others from previous activities that were not initiated orconstructed by Mosquito.
1.1 Purpose and Scope
This Reclamation Plan describes specific procedures to reclaim those areas utilized orby exploration activities. Reclamation of disturbed areas will be completed in accordance withfederal [36 CFR§228.8 (g)] and state [Areas proposed for disturbance can be divided into theroads (existing and new), drill sites, and stream crossings. Provisions made for reclaiming thesecomponents are described in Section 3. As noted, this plan also includes reclamation of existingtemporary roads that were constructed before this project and which the USFS desires to bereclaimed as a condition of approving the PoO.
1.2 Project Background
The CuMo prospect was discovered by AMAX Exploration Inc. (AMAX) in 1963. AMAX and theirjoint venture partners, AMOCOof exploration beginning in 1968 and continuing through 1982. During this time AMAXdeveloped a number of exploration access roads. In 2005 Kobex Resources Ltd., of Vancouver,British Columbia, approached the USFS with a plan to drill 16 exploration holes at the CuMoproject site. They developed a Plan of Operation (PoO) that included drilling and using theexisting network of unauthorized roads. The USFS determined that the proposed action met therequirements of a Categorical Exclusion, category 3 as described in 36 CFR 220.6(e). The planwas approved and bonded. Kobex began operations in summer 2006.
In the fall of 2006, Mosquito assumed control of the CuMo program and Kobex’s bonded 2005PoO. They began exploration drilling in summer 2007. The USFS signed a decision memo for arequest to extend the 2005 PoO on June 22, 2009. This request extended the 2005 PoO throughNovember 2009. On February 14, 2007, Mosquito submitted a new PoO to the USFS. Tplan sought to modify and replace the 2005 PoO and proposed up to 13.3 miles of new,temporary road construction, continued use of existing permitted roads, and up to 122 drillpads. The plan was accepted in a letter from the USFS dated March 5, 200

1.3 Forest Service Requirements
The 2003 Forest Plan for the Boise National Forest, as amended in 2010 (USDA, July 2003),describes management directions to guide Forest personnel in achieving desired outcomes andconditions for both land stewardship and public service. Management direction goals in theForest Plan call for appropriate mitigation and reclamation of environmental disturmineral exploration and development proposals.
The USFS does not have specific technical requirements related to reclamation plans. However,the USFS requires reclamation bonds for all proposed mineral activities that will potentiallycause significant surface disturbance and require reclamation (Forest Plan ManagementDirection MIST06). Bond calculations are performed by the Minerals Administrator and areintended to cover the estimated cost to perform reclamation work should Mosquito fail tbond will be collected and held by the Forest Service in order to ensure reclamation.
Guidelines used in the bond estimate to insure that the reclamation objectives have beenachieved include the following:
Structure demolition and debris handling
Road recontouring/reclaiming
Drill Pad recontouring/reclaiming
Sump reclamation
Seeding
Plugging open drill holes
Noxious weed monitoring
Road maintenance
Culvert maintenance
Additional standards and protocols developed herein address the mechanics of performing thereclamation work.

2.0 ANTICIPATED IMPACTS
This section describes current land uses of the project area and describes proposed explorationactivities that will cause land disturbance. Prior to initiation of work and throughout theexploration project, Mosquito will implement specific measures to bequality, terrestrial and avian wildlife, aquatics, vegetation, and cultural resources in accordancewith the EA. Those activities are generally not included in this Reclamation Plan, but areaddressed under other provisions of the EA,
2.1 Current Land Use
Current land use reflects a mixture of mining activities, wildlife habitat, and recreational use.Recreation activities include trail and ATV riders, rally racers, upland game and bird hunters,anglers, and other dispersed recreation. During the fall the Project Area is used for bighunting, and during the winter for snowmobiling and backcountry skiing. Other uses includecattle and sheep grazing and logging.
The activity area supports a mix of uplandGroup (PVG) 2 (Warm, Dry DouglasPVG 7 (Warm, Dry Subalpine Fir), andactivity area. According to the EA, riparian areas are located along Grimes Creek and severalsmall drainages that bisect the modified Activity Area. Except for the riparian area along GrimesCreek, riparian areas are generally narrow (approximately 10portion of the modified Activity Area. As stated in the EA, riparian areas would not bemeasurably affected by proposed activities except at the limited number of proposed roadcrossings. The seed mixes utilized for revegetation of disturbed areas wiconsultation with USFS and are based on existing vegetation types. In discussion with the USFSMosquito will utilize the appropriate seed mix for each vegetation type when plantingdisturbed areas.
2.2 Proposed Roads
Under the requirements of the EA, Mosquito may construct up to 10.2 miles of temporaryaccess roads to provide access to drill pad sites. Mosquito will submit to the USFS for its reviewand approval, temporary road plans for each phase of the project. As Mosquito apcompletion of construction of the first phase of temporary roads, its need for additional roadswill be evaluated and if deemed necessary, additional temporary road plans will be submittedto USFS for review and approval prior to construction. Speconstruction will be proposed and decided upon in consultation with USFS.

As a part of this Reclamation Plan, Mosquito also will reclaim existing temporary roads. Thoseroads are identified in Figure 3.
In collaboration with USFS, vegetation of areas slated for disturbance will be characterizedduring each phase of construction. Mosquito will utilize Potential Vegprovided by the USFS to overlay onto USFS approved road alignments and drill padThis will enable Mosquito to identify potential candidate species for reclamation and to plan forappropriate revegetation.
2.5 Topsoil Conservation
Topsoil is a critical component of our reclamation strategy because it is the critical mediumwhich each area’s pre-disturbance vegetation grew. For this reason, care will be taken toremove primarily topsoil and not “contaminate” it with subsoil. Once the topsoil is carefullyremoved, it will be stored in selected sites near the disturbed siteminimize its loss through erosion and storm water runoff.will be removed and transported with front loaders or graders.
