Mineralization · Layer 03 of 11
Ribbon-like quartz–carbonate bodies occupy faults near the Silver Cup Anticline and host Thor’s polymetallic mineralization.
01 · Vein anatomy
Quartz and siderite or ankerite form the vein framework. Sulphide minerals occur within it, recording the polymetallic character of the Thor system.
02 · Field evidence
At surface, resistant quartz-rich zones can form topographic highs. In core, quartz and massive sulphide reveal the mineralized vein interval directly.
Surface expression
Quartz and iron-oxide alteration exposed in the open-pit high wall.
Subsurface evidence
Quartz and massive sulphide characteristic of Thor’s epithermal deposit.
03 · System context
The epithermal veins form the upper, structurally focused expression of the system on the anticline’s southwest flank. Three-dimensional modelling brings mapped veins and drilling into one spatial framework.
Use mapping, structures and past drilling to choose the intersection angle.
Recover depth-controlled core and orient it when practical.
Record host rock, vein style, sulphides, alteration and structures.
Cut intervals across the vein and adjoining altered wall rock.
Insert standards, blanks and duplicates with the samples.
Analyze precious and base metals using appropriate laboratory methods.
Composite results, consider true thickness and update the 3D interpretation.
