ASSAYS CONFIRM HIGH GRADE COBALT MINERALISATION AND NICKEL SULPHIDE POTENTIAL AT THE PINNACLES PROJECT

Listed in 2006, Montezuma Mining Company Ltd (ASX: MZM) is a diversified explorer primarily focused on gold and manganese. The Company’s primary objective is to achieve returns for shareholders through selected strategic acquisitions and targeted exploration.

Montezuma has 100% interests in the Yamarna Gold Project in the Yamarna Greenstone Belt, the Holleton Gold Project in the Wheat Belt region and the Butcherbird Manganese/Copper Project in the Murchison region, all located in Western Australia.

HIGHLIGHTS

MARKET DATA

• ➢ High grade cobalt mineralistion up to 0.45% Co within a broad downhole intercept of 14m @ 0.15% Co .

• ➢ Drilling to provide sample material for preliminary metallurgical test work.

• ➢ Nickel sulphide potential confirmed based on Ni/Cu/PGE assay results and visible cloud sulphide.

• ➢ Bedrock conductor remains untested down plunge from existing drilling.

Montezuma Mining Company Ltd (“Montezuma” or “Company”) is pleased to advise that assays have been received from a reconnaissance drilling programme completed at the Company’s 100% owned Pinnacles Cobalt-Nickel Project to investigate a number of multi-commodity targets.

As previously announced, eight reverse circulation drill holes were completed for 1,335m to test multiple target types as follows:

Cobalt : Drillhole PNRC0003. Confirmation drilling of high grade cobalt identified in historic drilling[1] and supply of sample material for metallurgical test work.

Nickel sulphide : Drillholes PNRC0001, 2 and 8. Two late time bedrock conductors identified in a recent EM survey, one of which is located beneath a historic sulphide intercept of 2m @2.3% Ni[2] .

Gold : Drillholes PNRC0004-7. Historic work failed to analyse for gold in almost all drillholes however strong arsenic anomalism is clearly defined over significant strike lengths. Current programme tests for gold association within the arsenic enriched rocks.

ASSAY RESULTS

Cobalt

Drillhole PNRC0003, which was designed to validate the historical cobalt values intersected within the main laterite zone, has confirmed high grades over broad widths with a best intercept of 14m @ 0.15% Co , and a maximum cobalt value of 0.45% Co recorded over 1m from 35m downhole. This intersection closely matches the thickness and grade of intersections in nearby historical drill holes.

In addition to confirming historic work, the samples obtained from this drillhole will be the focus of first pass metallurgical testing to establish whether the laterite ores at the Pinnacles Project are amendable to low capital cost processing pathways. If the early test work is successful, the Company will commence investigations into the best way to commercialise the large areas of near surface cobalt rich laterite material within the project area.

Nickel

thickness. Visual observations and portable XRF readings indicated the potential presence of weakly disseminated (cloud) nickel sulphide within the ultramafic. Laboratory assays support these observations, and show that the likely magmatic sulphides are confined to discrete zones proximal to the margins of the ultramafic, with nickel/copper values up to 0.35% Ni/0.03% Cu (The non-mineralised ultramafic

averages ~0.10-0.22% nickel ). The location of sulphides and geochemical profile of the stratigraphy is typical of a differentiated ultramafic that is intrusive in origin. Petrology will now be completed to confirm these observations. The EM target remains untested and ranks highly given the presence of potential magmatic nickel sulphides within the host ultramafic and lack of other conductive lithologies encountered within PNRC0001.

Gold

The drill testing of historical geochemical anomalies and stratigraphic targets has revealed a number of strong coincident gold / pathfinder anomalies (Au-As-Bi-Te-Cu+/-Mo), and is indicative of the presence of a widespread hydro-thermal event. The recent results (supported by historical geochemistry) upgrade the potential for the discovery for gold mineralisation within the project tenure. Drill hole PNRC0007 was drilled to the west of the planned target due to restricted access, but still encountered strong alteration and shearing associated with the ultramafic/mafic contact.

The results also indicate that the ultramafic/mafic contact is a valid gold exploration target with anomalous gold (up to 116ppb Au) and other pathfinder elements (As-Bi-Te-Cu-Mo).

The information in this report that relates to Exploration Results, Exploration Targets, Mineral Resources and Mineral Reserves is based on information compiled by Mr David O’Neill who is a member of the Australasian Institute of Mining and Metallurgy. At the time that the Exploration Results, Exploration Targets, Mineral Resources and Mineral Reserves were compiled, Mr O’Neill was an employee of Montezuma Mining Company Ltd. Mr O’Neill is a geologist and has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’. Mr O’Neill consents to the inclusion of this information in the form and context in which it appears in this report

Please note with regard to exploration targets, the potential quantity and grade is conceptual in nature, that there has been insufficient exploration to define a Mineral Resource and that it is uncertain if further exploration will result in the determination of a Mineral Resource.
