The Project
CZL owns 51% of the high grade Plomosas Zn-Pb-Ag mine in MexicoWith the rights to acquire up to 80% interest (and ultimately 100%) for additional $750,000 cash and $1,700,000 shares.
Plomosas - Key Project AttractionsMultiple, very high grade Zn-Pb-Ag deposits grading 18-25% Zn+Pb with 60g/t Ag;
Granted Mining Leases (to 2042) - partly permitted - 4-6 month process
Significant additional exploration upside with immediate drill targets and 7Km strike;
A near term production asset with UG access to mineralisation already established;
Excellent infrastructure;
Historically clean mineralogy and high metallurgical recoveries;
Low cost and low capex mining and processing options (TBC).
4
Location
Plomosas Location2 hour flight from Dallas/Houston;
110 Km from Chihuahua City (95Km on state highway);
7 Km from established grid power
Chihuahua ProvinceWorld class mining province;
Experienced work force;
The country's largest zinc producing state.
MexicoFavourable regulatory environment allows 100% ownership for foreign companies;
Ranked #5 in world for mining investment (2015);
Ranked #6 for zinc production (2014).

Simple Geology
Shale-limestone units deposited at the margins of the major
Chihuahua sedimentary basin.
Deposits formed by mineralised fluids migrating through district scale structures and replacing carbonate units in the shale-limestone sequence, affinities to MVT-style.
Mineralisation is confined to identifiable stratigraphic horizons
as:
Low angle, stratiform sheets of mineralisation at several limestone-rich horizons in the sequence (mantos), or
High angle, crosscutting mineralised bodies in linking
structures (chimneys).
Replacive-style endo-skarns related to shearing within carbonate hosts.
Massive orebodies are found in groups with individual dimensions comprising:Strike lengths from tens to several hundred metres, and
Thicknesses from 0.5m to 15m (average ~3 - 4m)

Mining history 1945-1974
ASARCO Grupo Mexico operated until 1974.
Mined 2.5Mt ore at 24% Zn+Pb and 80 g/t Ag;
- Up to 20,000t ore per vertical metre;
Martinez family owned since 1978
Intermittent remnant mining since 1978 focused only on mineralisation above level 5 (131 mbs). Never dewatered;
3 shafts and multiple declines established and capable of extracting up to 1,000tpd (SRK report)
-
Historical concentrate information indicates very clean product and good recovery
No deleterious elements (cadmium, mercury, arsenic etc)
Highly sought after as a blending concentrate.
Established off-take agreement expires June.

CZL Work to Date
- Completion of whole of mine dewatering;
Ongoing geological mapping, sampling and surveying - Building on 3D model;
Identified new mineralisation in footwall - Tres Amigos (TA);
Drilling TA from underground phase 1 complete - high grades, variable thickness;
Surface drilling ongoing to determine dip and strike extensions;
Rehab complete in Level 7, developing additional drives for drilling positions;
- Confirmed mineralisation below Level 7 - significant de-risking step;
Initial metallurgical sampling complete;
Drilling on-going.

Exploration Areas
Underground Sampling areas showing the widespread nature of the high grade mineralisation;
Importantly no exploration drilling has been carried out below Level 7 and sub-levels;
Drilling at depth from Level 7 underway.

Exploration Targets
Zinc-Lead-Silver targetsProspective mineralised horizon upto 40mthickdipsatlowto moderate angles(Main Manto Horizon).

Level 7 Drilling
Semi-Oxide and Sulphide ZoneMapping and exploration work shows that mineralisation extends down dip from the upper levels down to Level 7 and sub-level Level 9 with no termination visible
Some semi-oxide mineralisation exists due to late-stage
brittle fracturing confined to a zone. Majority sulphides;
New geological model suggests orezone is boudinaged within a larger persistent shear zone, hosted within the manto;
Current mineralised zone is +400m in length, plunging to the south-east;
Historic assay values returned ave grades of 14 % Zn. Recent sampling returned ave of 32.8% Zn.
Completed drilling orezone from hangingwall access drive 1
Access drive 2 is complete and drilling will start May 3
3rd access drive planned and clean-up/rehab underway
