Analytical data

Result VESICLE CONTENT OF THE VESICULAR-GRANULAR PERLITE RANGES FROM 5% TO 30% BY VOLUME
Result THE ONIONSKIN PERLITE CONTAINS 0 TO 5% VESICLES BY VOLUME. TEST OF -50/100+ RAW PERLITEGAVE EXPANDED PERLITE DENSITIES RANGING FROM 23.6 TO 63.6 KG/CUBIC METER WHICH WAS FAVORABLE. MOST SAMPLES HAD PRODUCT RECOVERY YIELDS >90% WITH BAGHOUSE DUST OF 3-7% AND UNEXPANDED MATERIAL OR "SINKS" OF 0.7-2.5%.

Economic information about the deposit and operations

Development status Past Producer
Commodity type Non-metallic
Deposit size Medium
Significant No
Discovery year 1949

Ownership information

  • Type Owner
    Owner Tenneco Minerals Co.

Comments on the reserve resource information

  • GEOLOGICALLY INFERRED RESOURCES OF VESICULAR TO GRANULAR PERLITE AND PERLITE BRECCIA ARE ESTIMATED AT 18 TO 36 MTONNES. A GREATER QUANTITY IS PROBABLY PRESENT, BUT CAN ONLY BE VERIFIED BY DRILLING. THE ONIONSKIN PERLITE IS NOT PRESENTLY CONSIDERED AS A RESOURCE DUE TO LOCAL OBSIDIAN (MAREKANITE, APACHE TEARS) ZONES

Comments on development

  • A VERY BRIEF PERIOD OF MINING AFTER THE INITIAL DISCOVERY ENDED DUE A A HIGH PERCENTAGE OF OBSIDIAN NODULES IN THAT PART OF THE DEPOSIT. IN 1980, TENNECO RECOGNIZED PERLITE IN THE VICINITY OF TUCKER HILL AND STAKED THE PROPERTY IN 1981.

Deposit THE DEPOSIT CROPS OUT AS A NORTHEAST-TRENDING, STEEP-SIDED HILL WITH AN ELEVATION OF 150 M ABOVE THE ADJACENT LOWLANDS OF THE CHEWAUCAN MARSH. THE LONG AXIS OF THE HILL IS > 3.2 KM IN LENGTH AND THE WIDTH RANGES FROM 0.8 KM TO 1.6 KM; THE TOTAL AREA OF THE DOME EXCEDES 5 SQ. KM. THE DEPOSIT IS IN THE NORTHEASTERN PART OF THE DEVILS GARDEN LAVA FIELD ON THE CHILL MARGIN OF A LATE MIOCENE COMPOSITE RHYOLITE LAVA DOME WITH DIXTINCT COOLING ZONATION. THE CHILL MARGIN IS COMPOSED OF AN OUTER GLASS ENVELOPE CONTAINING COMMERCIAL-GRADE GRANULAR AND VESICULAR PERLITE AND AN INNER ENVELOPE WITH ONIONSKIN PERLITE. GLASSY RHYOLITE AND AND RHYOLITE COMPOSE THE DOME'S CORE. EROSION HAS REMOVED SIGNIFICANT PORTIONS OF THE CHILL MARGIN OF THE DOME. THE GRANULAR PERLITE IS INTERMEDIATE TO THE VESICULAR AND ONIONSKIN PERLITE.
