Hammer prospecting

Hammer prospecting consists of finding “indications” of mineralization by means of observing outcrop, landslides and debris from slopes or boulders. This is done throughout the itinerary prepared based on available documents: photo geological maps, outcrop, findings, geological, geophysical geochemical maps, etc.,  including information got from local dwellers. Not very much equipment needed and only in following phases will there be the need for floor samplers, light probing, etc., for the study of traces & possible found anomalies. Geologist is a wonderful Mining Job for any one

Description and use of instruments

A) Compass

There are different types of compasses and they can be used both for topographic removal and for geological purposes. Its expected that everyone know how to use one.

B) Reactors (dispersion)

Beforehand prepare some chemical blends and chemical products that make it easier to carry out observations of the soil. For example:

• Lime calibration with chloride acid diluted to 10%
• Qualitative analysis of the Pb: preparing a 50% blend of acetic acid at 5% (or HC1 at 10%) and 50% of iodine potassium at 5%. This reactor, poured on a sample containing lead will turn characteristically yellow
• Qualitative analysis of tin (cassiterite): place some grams of the mineral on a metallic zinc plate with an HCI concentrate. After a few minutes if its SnO2 it will form a small film layer of metallic tin, which can be seen by the naked eye, or using a magnifying glass or microscope.    

• For other analysis, go to the notes in the “Geochemical” course.
