Production statistics

  • Year 1989
    Accuracy Estimate
    Description Sand And Gravel Production 865650 Est. Mt Produced
    Importance Item Commodity Group Amount recovered Grade Recovery percentage
    Major Sand and Gravel, Construction Sand and Gravel 865650mt

Comments on the production information

  • NOTE THAT AS DESCRIBED HERE, RECOVERY OF ILMENITE, MAGNETITE AND APATITE WOULD BE 100%. THIS WAS DONE BECAUSE THE AUTHOR IS NOT SURE OF THE FINAL TREATMENT/RECOVERY PROCESSES. USERS SHOULD INCREASE THE MINING RATHER BY 20%. THIS WILL ALLOW FOR A RECOVERY RATE OF THESE MINERALS OF 80%; THIS WILL ALLOW THE OPERATION TO PRODUCE ITS PRODUCTS AT THE PROPOSED RATE SHOWN HERE.

Comments on the reserve resource information

  • M1=SAND AND GRAVEL ONLY. M2=ILMENITE RESERVES ONLY. M3=MAGNETITE RESERVES ONLY. M4=APATITE RESERVES ONLY.
  • THE PRESENT OPERATIONAL PLANT RECOVERS 85 PERCENT OF THE HEAVY MINERALS CONTAINED IN THE FEED. TESTS INDICATE THAT THE CONCENTRATES CONTAIN 33% ILMENITE WITH 50% TIO2 CONTENT 20% MAGNETITE, 27% APATITE AND 4.5% ZIRCON. THERE ARE 484 MINING CLAIMS ON WHICH GILLIBRAND ESTIMATES CONTAIN PROVEN RESERVES OF ILMENITE IN EXCESS OF 100 MILLION METRIC TONS. RESERVE NUMBERS THEREFORE ARE SHOWN FOR ILMENITE NOT FOR SAND AND GRAVEL. THE PERCENTAGES SHOWN ARE FOR AVERAGE GRADE IN THE SAND AND GRAVEL AND THE COUNTRY ROCK COMPOSED OF VARIOUS TYPES OF ANORTHOSITE. THE READER CAN MAKE HIS/HER OWN ESTIMATE OF HOW MUCH INDUSTRIAL ROCK IS AVAILABLE IN APPROXIMATELY 20 SECTIONS OF LAND WITHIN THE SAN GABRIEL MOUNTAINS.
