| Deposit | DEPOSIT IS A HEMATITE-MAGNETITE CONTACT METAMORPHIC DEPOSIT IN A SERIES OF METAMORPHOSED AND FOLDED SEDIMENTARY ROCKS NEAR CONTACTS WITH GRANITIC ROCKS. MAGNETITE AND MINOR PYRITE HAVE SELECTIVELY REPLACED THE LIMESTONE BEDS (THAT WERE MORE AMENABLE TO REPLACEMENT THAN ADJACENT SCHISTS AND HORNFELS) IN THE METASEDIMENTARY SEQUENCE. SURFACE OXIDATION REACHES TO A DEPTH OF MORE THAN 100 FEET; MUCH OF THE PYRITE IN THIS OXIDIZED ZONE HAS BEEN LEACHED. |
| Deposit | THE DEPOSIT WAS EXTENSIVELY DRILLED AND TESTED; PLANS WERE MADE TO PLACE THE PROPERTY INTO PRODUCTION BUT IRON PRICES FELL AND NO ORE WAS PRODUCED. ; INFO.SRC : 1 PUB LIT |
