Geologic structures

Type of structure Local
Structure description Normal Faults With Strike-Slip Component. Very Little Evidence Of Compression.

Ore body information

  • General form SERIES OF PODLIKE SHOOTS BETWEEN MULLIONS
    Strike NW
    Dip 50W
    Plunge direction W
    Thickness 0.5M
    Length 30M
    Width 15M
    Depth to top 0M

Controls for ore emplacement

  • Huahuaxtla Fault; Breccia; Tenor And Form Strongly Controlled By Long Mullions. Best Ore Down Dip Of Mullions In Limestone Footwall Breccia. Also In The Finer Shale Breccia Which Offers Max. Specific Surface.

Comments on the geologic information

  • BEDDING ATTITUDE IS STRIKE: NW; DIP 25 NE. FAULT ATTITUDES ARE SHALLOW NORMAL EW SET DIPPING S AND NE-SW SET, STEEPLY DIPPING.
  • SOMETIMES DEPOSITS ARE BELOW SMALL MOUNDS OF PROBABLE HOT SPRING ORIGIN.
  • POSSIBLY TWO PERIODS: EARLY ALONG HUAHUAXTLA FAULT AND LATER ALONG YOUNGER FAULTS ALSO. CONTROLLING FAULTS APPEAR VERY YOUNG. ORE NOT EROSIONAL LOCI. METACINNABAR AND CINABRIO NEGRO FOUND ONLY IN EARLIER DEPOSITS.

Economic information about the deposit and operations

Development status Past Producer
Commodity type Metallic
Deposit size Small
Significant No
Year of first production 1925

Mining district

District name Huahuaxtla District

Comments on the production information

  • THE ANOMALOUS PRODUCTION CITED FOR 1944 RESULTS FROM GUILLERMINA. ACCORDING TO CAREAGA, 1974, THE WHOLE STATE OF GUERRERO PRODUCED ONLY 5 TONS OF HG IN 1971 AND NONE IN 1970. IT IS INFERRED THAT PRODUCTION AT HUAHUATLA MUST BE VERY LOW.

Workings at the site

  • Type of workings Surface/Underground
    Length 500M
    Overall depth 45M

Comments on the workings information

  • THE ORIGINAL 3 WORKINGS (AURORA, ESPERANZA, AND SAN LUIS) ARE NOW CONNECTED. THERE ARE SEVERAL OTHER VERY SMALL DEPOSITS. GUILLERMINA, 1 KM TO THE NW, IS THE LARGEST OF THESE. IT LIES AT THE INTERSECTION OF THE ALICIA FAULT AND THE SHALE LIMESTONE CONTACT. IT WAS RICHLY MINED IN 1944 AND THPOSSIBLY TWO PERIODS: EARLY ALONG HUAHUAXTLA FAULT AND LATER ALONG YOUNGER FAULTS ALSO. CONTROLLING FAULTS APPEAR VERY YOUNG. ORE NOT EROSIONAL LOCI. METACINNABAR AND CINABRIO NEGRO FOUND ONLY IN EARLIER DEPOSITS.EN CLOSED BECAUSE BLOCKED OUT ORE HAD BEEN EXTRACTED. THE ANOMALOUS PRODUCTION CITED FOR 1944 RESULTS FROM GUILLERMINA.
