Linc Energy Stateline Lignite Project

Compiled a detailed drill hole database and geological reserve model for a large lignite property in Montana and North Dakota. HGC calculated a pro-forma mine plan with detailed resource estimates to prepare and initial JORC resource statement for the property.

United Coal Company

United Coal Company acquired DHDB as their primary drill hole database system. HGC provided installation, training and support for UCC personnel.

CONSOL Energy Fola Operations

Performed a comprehensive geological resource study for CONSOL's Fola Operations in Fola, West Virginia. The geological data for Fola had been collected over many years and numerous acquisitions. However, these data had never been compiled into a single database, modeled or had comprehensive resources compiled. The project consisted of scanning more than 2,000 drill holes into PDF format. HGC then rebuilt comprehensive a lithological and coal quality database. HGC perormed detailed coal seam and sand unit correlations across the project area. HGC created a large area stratigraphic model of all coal seams and the primary sandstone units. HGC then compiled detailed resource and reserve estimated across the Fola project area.

HGC performed a comprehensive geological resource study of CONSOL's Fola Operations - South Area. This project was the next phase of the large Fola project included drill hole data south of the first Fola project.

Peace River Coal, Inc. Roman Project Area - Trend Mine Area

Prepared a detailed geological audit of the Roman Project Area and the Trend Mine Area. The audit ranked levels of completion for geological tasks and components with respect to PRC's drill hole databases and geological models.

Kennecott Uranium Company Rio Tinto Energy America

Compiled In-Situ Uranium Resource Estimates for six (6) properties held by the Green Mountain Mining Venture (GMMV), a wholly owned subsidiary of Kennecott Uranium Company. HGC developed detailed Block Model estimating uranium grade for each property.

HGC assisted Kennecott Uranium Company scan and process close to 10,000 drill holes for multiple uranium deposits in Wyoming. Customized DHDB to store all of the drill hole data. Developed custom programs in DHDB to load, and convert geophysical log Gamma counts into uranium grade. Acquired the Neuralog geophysical log processing software to trace gamma log data for the drill hole data.

Marston & Marston, Inc.

Assisted Marston in performing a technical review of geological models for the Ovoot Tolgoi coal deposit in southern Mongolia.

Colowyo Coal Company, LP Rio Tinto Energy America

HGC managed the geological information collecting during the 2004, 2005 and 2006 Collom Exploration projects and the 2006, 2007 and 2008 South Taylor Exploration projects. HGC developed programs in DHDB to efficiently enter and store comprehensive geotechnical information in conjunction with lithological and coal quality information. HGC expanded the geological reserve model of Colowyo to include all mineable resources in the area.

HGC prepared year-end annual resource and reserve reports for the Colowyo mine for 2004, 2005, 2006, 2007, 2008 and 2009. HGC reviewed the year-end reserve reports for the Decker Mine on behalf of RTEA in 2006, 2007 and 2008.

HGC prepared the “South Taylor Geology Feasibility Report” as part of the South Taylor Mine development project. HGC prepared the Collom Area Geology Pre-Feasibility report for Collom Mine Area as part of the Collom Area Mine development project.

HGC, in conjunction with Dodd and Dodd, Associates and CoalGeo, LLC, prepared a Competitor Analysis Summary of the mines in Colorado competing with Colowyo. RTEA marketing personnel used the report to gague Colowyo's future position in the coal markets of western Colorado.

Corporate Projects Rio Tinto Energy America

HGC compiled geological and mining summary reports for each Rio Tinto coal property to be submitted on behalf of the Rio Tinto competent person. HGC reviewed mining recoveries for each Rio Tinto coal property to determine the tonnage of ash and moisture shipped annually.

Quality Control Department Kiewit Mining Group

HGC developed a database to store and report Quality Control incidents for Kiewit Mining Group. The Access based front-end is linked to tables in SharePoint. Thus Kiewit quality control personnel from Wyoming, Montana, Texas and Nebraska can all effectively utilitize the central data via a local front-end. The database and reports reduce the time required to compile monthly quality data from more than a day to minutes.

Environmental and Permitting Department Kiewit Mining Group

HGC developed an Access database to store and report Reclamation History for the Decker and Buckskin mines. The database provides comprehensive input of all data related to each mines' reclamation history. The database reduce the time required to prepare annual reports and greatly expanded Kiewit's knowledge base, while streamlining reclamation history data.

Black Butte Coal Company Kiewit Mining Group

HGC updated the geological models for the Pit 14 mine area. HGC prepared a detailed suite of maps and reserves for BBCC as a marketing tool for Pit 14. HGC prepared detailed geological cross-sections for the Pit 14 permit.

HGC developed a post-mine topography map for Pit 9 reclamation.

HGC performed a 30 hole exploration drilling and coal sampling program for the Black Butte Mine. The program consisted of coal core sampling, monitor well installation and geotechnical logging of continuous core holes.

Washington Group International

HGC worked in conjunction with WGI to update four multi-seam structurally complex geological reserve models at the TransAlta Centralia Mine. Updated DHDB to incude washability and designed a utility in Access to determine product quality (yield, ash, sulfur and Btu) from washability data.

Ark Land Company

Developed geological models for a coal mine in southwestern Wyoming. Processed geophysical logs for geological correlation.

North Rochelle Mine Triton Coal Company, LLC

Updated the coal quality model for the North Rochelle mine. Updated procedures for reporting composite coal quality for mine planning.

Klohn Crippen Berger Ltd

Correlated overburden strata for more than 1,200 drill holes for an oil sand mine in Alberta. HGC also prepared a detailed drill hole database and stratigraphic model for KCBL.
