An integrated, mineral systems approach to generating & advancing blind Carlin-type gold projects. PRESENTED BY Simon Griffiths Senior Technical Advisor / Nevada Exploration Inc.
Slide 2: Talk Outline
Talk Outline • What is the “Mineral System” approach? – The Carlin Type Deposit Mineral System • Exploration program design & execution – Regional Scale – Camp Scale Program – Prospect Scale Program • Results – South Grass Valley model & 2020 program – Wrap-Up /2
Slide 3: What is the "Mineral System" approach?
What is the “Mineral System” approach?
Slide 4: What is the "Mineral System" approach?
What is the “Mineral System” approach? • Mineral systems are complex & dynamic • Process based exploration concept: – Scale of features depends on scale of relevant geological process to be tested CRITICAL ELEMENTS Fertility Geodynamics Architecture Depositional Process Host structure dilational Pro
Slide 5: The Carlin Type Deposit Mineral System
The Carlin Type Deposit Mineral System • Regional scale footprint: – Narrows search space for mineral districts – Enables us to recognize common controls From Muntean, 2018. /5
Slide 6: The Carlin Type Deposit Mineral System – Camp scale
The Carlin Type Deposit Mineral System Northern Carlin Trend Camp scale features: (Au deposits shown in yellow) – Endowment: many known Au deposits – Tectonic stress Little Boulder switch: inversion of Goldstrike Stock Basin Stock pre-Eocene normal faluts (Muntean, 2018) – Major heterogeneity: Boots
Slide 7: The Carlin Type Deposit Mineral System – Prospect scale
The Carlin Type Deposit Mineral System • Prospect scale characteristics: – Understanding of ore deposition processes allows target area ranking – Challenge is bias - data rich/data poor areas From Muntean, 2018. /7
Slide 8: Exploration program design & execution
Exploration program design & execution
Slide 9: Regional Scale Program
Regional Scale Program • Public domain literature / data review – Geological, geochemical & geochronology – Re-process geophysics (magnetics, gravity) • Extensive hydro- geochemistry program • Ranked list of new camps under cover /9
Slide 10: Camp Scale Program Design
Camp Scale Program Design • Reconnaissance Goodwin Butte mapping / sampling • Geophysics Lower Plate • Soil & water Window Mag. Lineament geochemistry Roberts Mountains Thrust (fault?) • Geochronology • Core drilling Goodwin Butte Source: USGS / 10

Slide 12: Prospect Scale Program
Prospect Scale Program Key features to test at Major Geologic Units this scale include: – Host structure dilational / pipe-like rock volumes (fold axes/hinges). – Favorable host sequence. / 12
