Comments on the reserve resource information

  • M1C1 + M1C2 + M1C3 = M9C4. M1C1 IS THE ANIMAS MINE OF THE CHOCAYA GROUP, M1C2 IS THE SAN VICENTE MINE, M1C3 IS THE TATASI MINE.
  • THE QUECHISLA GROUP OF MINES IS COMPRISED OF SOME OF THE MOST PROMISING SILVER DEPOSITS IN BOLIVIA. SIETE SUYOS-ANIMAS, TATASI-PORTUGALETE, AND SAN VICENTE ARE SILVER BASE METAL VEIN DISTRICTS IN TERTIARY ROCKS ASSOCIATED WITH TERTIARY VOLCANISM. SAN VICENTE RESTARTED OPERATIONS IN 1987 AT THE RATE OF 400 MTPD OR AT 420 G/T AG, AND 4% ZN AND THE OTHER TWO WERE DUE TO RESTART IN 1988. EACH MINE COULD PRODUCE 1,000 TPD FOR A TOTAL OF AS MUCH AS 8 MILLION OUNCES OF SILVER PER YEAR.
  • RESERVE BASE EXTENDED AS PER B-H REPORT AND ARTICLES. RESERVES IN MARCH 1988 E/MJ, P. 53.

Comments on other economic factors

  • UNITS OF CAPACITY ARE IN MT ORE/YEAR
  • U1 IS PRODUCTION FROM THE CHOCAYA (ANIMAS) MINE; U2 IS THE TATASI MINE; U3 IS THE SAN VICENTE MINE. CHOCAYA HAS SERIOUS (2400 GAL/MIN) WATER PROBLEMS HAMPERING LOWER LEVEL DEVELOPMENT/ DILUTION PROBLEMS, FROM 50-100%, ARE THE RESULT OF NARROW VEIN WIDTHS AND A CONTRACT BONUS SYSTEM THAT REWARDS THE WORKERS ON THE BASIS OF STOPE WIDTHS BROKEN. UNITS OF CAPACITY ARE IN MT ORE/YEAR.
