1 Silver Exploration in Mexico Status Report o Seminario Internacional de Minería Sonora 2014, AIMMGM A.C. by Matthew D. Gray 22 October 2014
2 Conclusions Mexico is desirable location for silver exploration Exploration success and production from: 1. LSE - low sulfidation epithermal deposits 2. CRD - carbonate replacement deposits 3. IRP - intrusive related polymetallic deposits
3 Conclusions Success coming from new districts Success coming from non-traditional sources Successful companies commit to drilling Exploration opportunities exist for aggressive explorationists willing to test concealed or conceptual targets

31 10 largest 2013 Ag producers Only 3 of the most productive silver mines are in the historic silver districts
32 The future Where will the silver be coming from in 2024? From new districts and from deposit types that historically have not been major silver producers.
33 New districts
34 Ag resources, 2013
35 Ag resources, 2013
36 Ag resources, 2013 New silver resources being developed outside of historic districts
37 Ag resources, 2013 New silver resources being developed outside of historic districts and away from active mines
38 Non-traditional deposit types
39 Ag Exploration in Mexico Directed at Three Important Ag Deposit Types* 1. LSE - Low sulfidation epithermal **(vein and stockwork/disseminated) Example: Fresnillo 2. CRD Carbonate replacement deposit, polymetallic Example: Santa Eulalia 3. IRP - Intrusive related polymetallic, direct spatial and/or genetic link to intrusives Example: Peñasquito Note: LSE and CRD also related to intrusives, but IRP s distinguished by direct association * Not genetic classifications! Based on basic economic characteristics! ** Includes intermediate sulfidation systems as per Hedenquist classificactions.
40 Non-traditional deposit types IRP deposits will become increasingly important producers of silver
41 Major Ag mines, 2013 Current silver production from a variety of deposit types
42 Major Ag mines, 2013 Current silver production from a variety of deposit types
43 Major Ag resources, 2013 Future silver production from IRP and LSE deposit types
44 Major Ag resources, 2013 Future silver production from IRP and LSE deposit types
45 What are companies looking for? 1. LSE - Low sulfidation epithermal (vein and stockwork/disseminated) Most productive deposit type historically Ag/Au and Ag/Pb/Zn systems, but high grade systems can stand alone economically on Ag content Best bet for a high grade primary Ag producer Juanicipio/Valdecañas 601 gpt Ag Saucito 384 gpt Ag Fresnillo 271 gpt Ag
46 What are companies looking for? 2. CRD carbonate replacement deposit Ag-Pb-Zn Can be high grade Ag, but typically co-product metals essential for positive economics La Platosa La Encantada 553 gpt Ag 227 gpt Ag
47 What are companies looking for? 3. IRP - Intrusive related polymetallic Polymetallic systems, Ag-Au-Pb-Zn Large scale, >100 M tonnes Low grade Enormous Ag resources due to their large size, but Ag is normally a co-product Peñasquito 605 M oz 30 gpt Metates 526 M oz 14 gpt Cordero 489 M oz 21 gpt Pitarilla 479 M oz 95 gpt

54 Silver deposits and geology
55 Silver deposits and geology
56 Observation 1. Direct discovery in outcrop still possible in underexplored areas Ixtaca, Puebla (Almaden) Promontorio/La Negra, Sonora (Kootenay)
57 Observation 2. If system is exposed in outcrop, significance might not be easily recognized. Ore bearing portion possibly concealed uninteresting narrow structures may reflect significant Ag deposits at depth
58 Observation 3. Concealed systems provide no direct surface evidence San Sebastian, Durango demonstrates potential for discoveries in areas without any historical precedent of mining/exploration about 3m away from being completely blind
59 Observation 4. Large productive systems may have small and subtle footprints Some systems have extensive high level alteration zones, but many exposed productive LSE and CRD systems lack extensive surface hydrothermal alteration, thus no color anomaly or widespread alteration
60 I m standing in the midst of 1 billion ounces of silver. Where is the color anomaly? Pinguicos Shaft, Guanajuato
61 He is standing on the vein. Where is the alteration halo? Peñon Blanco, Zacatecas
62 Observation 5. Surface geochem cannot directly identify blind or deep targets Blind CRD orebodies notoriously difficult to find using geochem LSE barren zones are truly barren of metals of interest Surface expression of productive LSE system may yield only a weak pathfinder Hg anomaly
63 Exploration Considerations in Mexican Deep Boiling Systems argillic / advanced argillic HT breccias amorphous silica (silica cap) hypogene argillic propylitic halo Information from Albinson et al. 2001, Buchanon, 1981
64 Exploration Considerations in Mexican Deep Boiling Systems alteration tightly restricted to structure no Au or Ag anomaly, possible Hg anomaly Ag-Au-Pb-Zn barren m m Information from Albinson et al. 2001, Buchanon, 1981
65 Exploration Implications Evaluation of Prospect Grade at surface not a make-or-break factor Seek indications of level of exposure Extent of mineralizing system Showings dispersed over wide zone or localized on a single structure? Evidence of dynamic HT system? HT breccias, cross cutting veins, etc.
66 Exploration Implications Must drill! In mature districts, outcropping ore will not be found today, therefore must drill within favorable system
67 Exploration Implications Must drill! This is common sense, but many exploration companies forget this rule, (or can t afford to respect it!) leaving opportunities for others
68 Exploration Implications Must drill! LSE and CRD systems are not tested with small drill programs Drilling a discovery hole at the outset is extremely unlikely The first drill campaign provides the information needed to understand zoning and vectors in the system
69 The good news New discoveries are waiting to be made!
70 The bad news Won t happen anytime soon!
71 The bad news Requires large drill budgets hard to obtain for most explorers in today s financial environment. A few drillholes in a complex target will almost certainly fail, so must commit to an adequate drill test, or money spent drilling is a mis-use of exploration budget. Successful companies understand this is it a coincidence that Fresnillo PLC, the world s largest silver producer, commits $100M US annually to drilling?
72 Conclusions Mexico is geologically, politically, and logistically desirable location for silver exploration investment Exploration successes with LSE, CRD, and IRP deposits Successful exploration requires commitment to drill Opportunities exist for aggressive (well funded) explorationists
