Controls for ore emplacement

  • Contact Zone Between Metasediments And Idaho Batholith
  • FAULTING
  • IGNEOUS

Comments on the geologic information

  • Graphitic Schist 25 Ft. Thick, Trends N 70 Deg E, Dips 51 Deg NW
  • The Graphite Schist Is Probably A Tabular Shaped Deposit, But So Little Info Is Available On the Deposit That Benjamin Was Unable To Make An Accurate Estimate of the Strike, Dip, Or Dimensions of the Graphite Zone. It Is Most Likely Folded Faulted and Intruded, Making the Deposit Shape Even More Complicated. The Dimensions Given In the Data Set Are Those of the Ore Zone Postulated By Benjamin, See Appendix B-2 of the Report For A More Detailed Description.

Land status

Ownership category National Forest
Area name Challis National Forest

Ownership information

  • Type Owner
    Owner Niece, Jack R.
    Interest 100
    Home office Idaho
    Year 1983

Comments on the ownership information

  • Jack Niece Holds the Shorty Claims (15 Claims). Joel Olsen Holds the Stanley Ace Claims (3 Claims). Jeff Jones States the Shorty Claims Have Been Declared Invalid and the Stanley Ace Claims Will Be Declared Invalid By the National Rec Area the Owners Are Contesting This Action By the Rec Area.

Comments on the production information

  • Mill Produces 22.70 Mt of Graphite Each Day 17.35 Mt of Packing Grade: 88.5 % Graphite Carbon, 95 % Retained On A 325 Mesh Screen. 5.35 Mt of Powder Grade: 95 % Graphite Carbon 5 % Max On A 325 Mesh Screen.

Reserves and resources

  • Type In-situ
    Estimate year 1974
    Indicated 281000mt ore
    Demonstrated 281000mt ore
    Total resources 281000mt ore
    Commodity Subtype Grade units Group Importance Year
    Graphite C 2.5 g/mt Graphite Major 1974

Comments on the reserve resource information

  • Very Little Data Is Available On the Shorty Claims. The Area Has Extensive Soil Cover With Very Few Outcrops. Graphite Schist Is Present In Isolated Outcrops Along the East Flank of Elk Mt (4km Strike Distance). It Is Not Possible (Based On the Little Info Available) To Make An Estimate of the Total Graphite Schist In the Area, Except To Note It Must Be Many Tens of Millions of Tons. Benjamin Feels A Resource Estimate For A Small Portion of the North End of Elk Mt Can Be Made (The Area Most Highly Trenched and Sampled). This Is the Estimate In the Q Matrix For A Detailed Picture of How the Resource Was Calculated See Appendix B-2 of the 1983 Mas Report.

Workings at the site

  • Type of workings Surface/Underground
    Length 111.56M

Comments on the workings information

  • All Adits Caved and Inaccessible
  • The Proposed Mine-Mill Site Is In the Sawtooth National Recreation Area, An Area of Great Natural Beauty. The Mine Operators Would Be Under Continual Pressure To Run A Very Clean Operation. No Waste Products Would Be Allowed To Enter Elk Creek. Elk Creek Is A Tributary of the Salmon River (One of the Premier White Water Recreation Rivers In the USA)

Comments on development

  • 9 Unpatented Claims
