Detailed, geological and mineralogical notes compiled on posting sheets (“fact maps”), whose color and textural distinctions allow quick visual correlation of common features between outcrops, mine benches, or drill holes

The field-based methods presented in this article have proven useful in porphyry exploration for decades. The application of the Anaconda method of geologic mapping and core logging by geologists can assist in the targeting of high-grade cores of deposits and improved estimation of metal resources.

The attached zip file contains an excel spreadsheet with assays from a drill hole cross section through a major porphyry Cu-Au deposit, merged with the logged rock types from the site geologists.

This review examines the geochemical and mineralogical indicators of deep porphyry systems and evaluates the effectiveness of ASTER in their exploration.

The attached sheet has proven to be very suitable. It separates the key elements of the log: drilling, strength, weathering and structures while keeping them all on the same sheet and thereby minimises repetition of data entry.

The habits most relevant to porphyry deposits are reviewed in the book Porphyry and Epithermal Deposits: Mineralization, Alteration and Logging (Godwin, 2020). Descriptions are repeated here but often in more detail.

This document provides standard geological codes and abbreviations to be used for logging and mapping rock samples. It includes lithology descriptions and codes, sample class descriptions and codes, mineral descriptions and codes, descriptive terms for structures, textures, colors and alterations.

His course is a concise yet highly informative summary of the latest research on the exploration of porphyry and epithermal systems, as well as the interpretation of analytical data, where Federico shares numerous practical tips.

A guide for field methods, descriptions, data collection and logging to improve your understanding of geology, mineralization and alteration in the search for porphyry and epithermal deposits.
