Crowley Adit #1 10/13/2022
At Crowley #1 Looking Back at portal.
Crowley Adit #1 Good ancylite mineralisation on right rib. Could the patches have been single large crystals originally?
Crowley Adit #1 Pegmatitic calcite (white) and biotite (black). At 705'.
Çrowley Adit #1 Augen gneiss near back of tunnel.
Crowley Adit #3 portal View is a quartz-feldspar dike.
Crowley Adit #3 At the "T". The exposed vein is roughly 2 feet across. The ancylite-rich band is > 10% combined La + Ce, based on XRF.
Pink is ancylite rich. White is calcite. Pale yellow is calcite, barite. Black is actinolite, biotite, maybe some allanite, magnetite. Arrows point to monazites (1cm).
Crowley Adit #3 Right (east) stope. Beautiful banded carbonatite exposed near top of right rib. Dippling about 50° to the north.
Same spot, different view. Peter is taking a dip measurement.
Same spot, Sarah for scale. Box on next page.
Same spot. Close up showing black allanite (?) + amphibole, biotite. Honey-colored spots probably monazites.
Ancylite rich zone exposed on back. Here the clean (exposed) part of vein is about 1 foot wide. Note the different shade of pink with the ancylite rich bands.
Beautiful banded carbonatite exposed near top of right rib. Approximately 4 feet of vein here, not counting calcite stringers in footwall and hanging wall.
