Promesa Ltd (“Promesa”, “the Company”) is a Perth based ASX listed Company, with a substantial portfolio of exploration concessions in Peru. The Company has six projects in Peru, three projects in La Libertad, two projects in Ancash and one project in Huancavelica Departments. The Alumbre project is advanced to drill-ready stage.

ALUMBRE PROJECT

Background

The Alumbre Project is a potential Au-Cu-Mo porphyry system located 70km southeast of Trujillo in northern Peru (refer to Figure 1). The project is serviced by the nearby Pan Americana Highway and includes good infrastructure to the project area. The Alumbre Project area consists of approximately 2,200ha which adjoins a larger regional concession holding area of approximately 24,600ha. Promesa is has control of the concessions either through outright ownership of through option to purchase agreements.

The Company has completed extensive exploration work on the Alumbre Project. This includes detailed geological mapping, rock geochemistry, ground magnetics, induced polarisation (IP) geophysics and alteration mineral mapping. Alteration

view.

Various intrusive rocks, subvolcanic rocks and porphyry related hydrothermal alteration exist. The petrographic study has confirmed the centers of phyllic alteration. This alteration type, containing quartz, sericite and pyrite, generally carries copper mineralization in economic porphyry systems. The area exhibits the zoned alteration styles expected in porphyry systems grading from propylitic in the outer parts of the system to phyllic alteration in the central “hotter” parts of the porphyry system where the bulk of mineralization would be expected. The rocks are variably stockworked and contain disseminated sulphide, mostly pyrite, with traces of sphalerite, chalcopyrite, chrysocolla, digenite, monazite, pyrrhotite and cassiterite.

Figure 2 - Alumbre Project showing the very strong Chargeability response at a depth of 400m and the drill pad location of the 3 stage 5,600m proposed Diamond Drilling Program. The Stage 1 drill program includes 7 platforms with a total 2,200m being drilled.

The Company plans to undertake up to 2,200m of diamond drilling from 7 drill platforms in a first stage program as illustrated in Figure 2. This is the first part of a larger three stage 5,600 m drill program. Hole depths vary between 150m and 500m. Drill targets are associated with high chargeability anomalies at Alumbre with supporting surface geochemistry and alteration mineralogy.

Exploration Update

Recently our Country and Exploration Manager Mr. Dean De Largie has just returned back from Peru. As part of his visit Dean completed a site visit of the Alumbre Project Area to evaluate the progress of current exploration field work and preparation of drill platforms, field services and access tracks.

Figure 3 – Illustrated deposit model of a porphyry copper deposit (modified* from Lowell and Guilbert, 1970). (A) Schematic cross section of hydrothermal alteration minerals and types, which include propylitic, phyllic, argillic, and potassic alteration. (B) Schematic cross section of ores associated with each alteration type.**

During his site visit some new and important observations where documented and photographed with respect to the project’s porphyry potential that support the company’s geological model at the project area. Field observations compare favorably to the classic porphyry model system as illustrated in Figure 3. In the classic porphyry model a broad pyrite shell has within it thinner band of increased Cu content. The pyritic shell is the key exploration target and from that target, the prospective ore zone can be targeted for drilling.

Figure 4 illustrates a regional overview of the project area looking down the hill over platform 7 towards the camp. Of particular interest is the change in colour of the track towards the platform. The reddish colouration in the track increases between the camp and platform 7. This reflects the increased iron content from the oxidation of pyrite. Quartz-pyrite stockworking is present on the far side of the peak of the hill in the distance and at platform 7 and in the region of platforms 11 and 13 (see figure 3 and 4).

Figure 5 shows moderate to strong quartz stockworking, strong iron oxide development in both the intrusive rock itself and associated with the stockwork veinlets. The stockworking has been exposed during access track and drill pad and sump preparation. The drill platforms were positioned to target highly chargeable areas identified from the induced polarization (IP) geophysics program. The newly observed stockworking at the drill pad locations further validates the Company’s exploration model.

Deep red hematitic vein borders can be clearly seen. Although the rock is moderately oxidized, disseminated pyrite can still be seen in the intrusive at this location. The rock has moderate iron oxide development after pyrite. The location corresponds to the outer western side of the Alumbre chargeability anomaly in Figure 2.

Figure 6 – Stockwork at drill platform 7 site.

Figure 6 is from the site of drill platform 7 which is our first drill hole site. The area observed shows strong stockwork development in the intrusive rock, which has undergone multiple vein formation episodes, fracturing and faulting. Moderate jarosite (a potassium iron oxide) is observed probably from the oxidation of pyrite. In the bottom right of the figure dark reddish brown goethite and hematite have developed from the oxidation of pyrite.

Figure 7 illustrates strong stockworking and the violent emplacement process and gas/fluid emanation resulting in very a strongly altered intrusive. This area corresponds to the western side of the chargeability anomaly. The veins exhibit moderate to strong hematite development probably after pyrite though original sulphides have been destroyed at this location.

Appendix A - JORC Code, 2012 Edition – Table 1

Section 1 Sampling Techniques and Data – Alumbre Project

Criteria	JORC Code explanation	Commentary
Sampling techniques	 Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.	Promesa Limited (“Promesa” or “Company”) has completed mapping, geophysics a field rock sampling program of approximately 1,100 samples in the project area. The company has not undertaken any drilling to date in the Alumbre Project area.
	 Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.	Sampling program is undertaken on a 100m by 100m grid reducing to a 50m by 50m grid where further definition has been warranted. Rock sampling is achieved by the collection 2 metre continuous channel samples or continuous chips in the shape of a cross over a circular area with diameters between 0.5 and 2 metres as appropriate for the sample location using a geological sampling hand tools. The sample locations are picked up by handheld GPS at the time of sampling. Sampling was carried out under Company’s protocols, management and QAQC procedures as per industry best practice.
	 Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.	Field samples are generally between 2 and 3kg per sample. Samples are sent to a certified assay laboratory and are crushed, dried, pulverised using Acme Prep code R200-250. The sample is crushed until 80% passes under a 10 mesh size fraction. This 80% is then split to subsample 250gm which is then pulverised until 85% passes under 200 mesh size fraction. Analysis is by Acme Analysis codes G601 and 1F04. G601 is a fire assay for Au using a 30g subsample followed by ICP for a detection limit of 2ppb. 1F04 is an ultra-trace level analytical method using a hot modified aqua regia digestion with equal parts of nitric acid, hydrochloric acid and water of a 0.5g subsample analysing 53 elements by ICPMS and ICPES as appropriate. Elements and their respective lower and upper detection limits for the primary commodities are Ag 2 ppb-100 ppm;; Au 0.2 ppb-100 ppm;;Cu 0.01 ppm-10000 ppm;; Mo 0.01

			massive in texture, ensures an appropriate degree of representativeness whilst minimizing the possibility of sample bias. The sample preparation surface samples follows industry best practice in sample preparation All samples are pulverised utilising appropriate industry standard grinding mills determined by the size of the sample. Samples are dried, crushed as required and pulverized to produce a homogenous representative sub-sample for analysis. A grind quality of 85% of a 250g, sub 2mm subsample passing through 75μm is achieved.
		 Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.	Promesa quality control and assurance has been achieved by the use of blanks and certified reference material (CRM’s) standards of known mineral content into each batch of samples. Additionally duplicate samples are taken approximately every 20th sample. Acme and ALS-Chemex laboratory also insert blanks and standards into each batch. Certified Reference Materials (CRM’s) and/or in house controls, blanks, splits and replicates are analysed with each batch of samples. These quality control results are reported along with the sample values in the final report. Selected samples are also re-analysed to confirm anomalous results.
		 Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling.	Field duplicates have been taken approximately each 20thsample. Total sample preparation is conducted irrespective of sample weight.
		 Whether sample sizes are appropriate to the grain size of the material being sampled.	Sample sizes are considered appropriate to give an accurate indication of mineralisation given the qualitative nature of the technique.
Quality of assay data and laboratory tests		 The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.	Initially samples were sent to ALS – Chemex Laboratory services which undertook Fire Assay using a 30 gm charge and a multi-element ICP analysis was utilized. Both ALS - Chemex and are ISO 9001 certified. Acme Analytical Laboratories are currently used by the ~~company and are ISO~~9001-2008 certified Lab with Cert

		No FM63007. The Lab systematically inserts blanks, standards and runs random duplicate assays and duplicate assays on high grade samples. Gold is assayed using a 30gm fire assay with an Atomic Absorption finish. Multielement ICP-mass spectrometer analysis is used on a suite of 53 elements after an aqua regia digestion. The digestion is considered to be partial. This method is appropriate to detect anomalous gold mineralisation.
	 For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc.	No geophysical tools were used to determine any element concentrations.
	 Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established.	Sample preparation checks for fineness were carried out by the laboratory as part of their internal procedures to ensure the grind size of 85% passing 75 micron was being attained. Laboratory QAQC involves the use of internal lab standards using certified reference material, blanks, splits and replicates as part of the in house procedures.
Verification of sampling and assaying	 The verification of significant intersections by either independent or alternative company personnel.	Logging and assay data undergoes a number of in- house supervisory, authentication and quality control processes. Log data of samples is entered in by geologists field notebooks and entered into a computer nightly and emailed to a dedicated sample and assay database manager. The resultant database is further checked by senior company personnel.
	 The use of twinned holes.	NA – no drilling has been undertaken by Promesa at Alumbre.
	 Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.	Primary data was collected using a set of standard Excel templates using lookup codes. The information was sent to an in-house database manager for validation and compilation into an onsite Access database.
	 Discuss any adjustment to assay data	No adjustments or calibrations were made to any assay data reported.

Criteria	JORC Code explanation	Commentary
Location of data points	 Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.	NA - exploration activity to date will be able to be used to in the determination of Mineral Resource estimation.
	 Specification of the grid system used.	Present data uses a WGS84 grid system zone 17.
	 Quality and adequacy of topographic control.	All samples are located by handheld GPS. Expected accuracy is +/– 5 m for easting, northing and 5 m for elevation coordinates.
Data spacing and distribution	 Data spacing for reporting of Exploration Results.  Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.  Whether sample compositing has been applied.	NA - Alumbre project area is at an early exploration assessment. Work current does not support Mineral Resource and Ore Reserve estimation.
Orientation of data in relation to geological structure	 Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.	The methods used to take chip and channel samples eliminate as much as practicable sample bias due to structure.
	 If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.	NA
Sample security	 The measures taken to ensure sample security.	A chain of custody of samples is used and managed by Promesa. Samples are stored on site and either delivered by Promesa personnel to the assay laboratory in Trujillo or Lima in Peru. Whilst in storage, they are kept on a locked yard. Tracking sheets have been set up to track the progress of batches of samples.
Audits or reviews	 The results of any audits or reviews of sampling techniques and data.	Repeated sampling exercises validate sampling of previous workers. Management reviews sampling techniques regularly in the field. External training in sampling techniques and QAQC is provided.

Section 2 Reporting of Exploration Results – Alumbre Project

Criteria	JORC Code explanation	Commentary
Mineral tenement and land tenure status	 Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.	The Alumbre project area is located at low attitude, in the Department of La Libertad in northern Peru. There are no historical sites, wilderness or national parks or environmental issues. The current project area consist of group of concessions with one concessions which is 100% owned by Promesa Limited, plus four other adjoining concession which are subject to option agreement, these include three concessions owned by Oban S.A.C which allows 70% farm-in and includes an NSR royalty and one concession owned by Compania Minera Fabrico S.A.C. which allow 80% farm-in and includes an NSR royalty.
	 The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.	Concessions and agreements are in good standing and the company has social and government approvals in place to explore.
Exploration done by other parties	 Acknowledgment and appraisal of exploration by other parties.	The region was explored by Santa Cristina de Chorobal from 1993 to 1994 and Newmont, from 1994 to 1996, undertook regional exploration work. Savage Resources (later bought by Pasminco) from 1996 until 1999 had undertaken sampling, mapping, geophysics and drilling within some of the current project area at Alumbre. Savage Resources had undertaken a nine-hole RC and RC/Diamond drill program and 573 rock sampling program along channel of various lengths from 1 to 27m in length within part of the Alumbre area. Historical Savage RC drill samples were composited up to 4m and diamond drill holes were composited up to 2m. This drilling produced anomalous results which were considered worthy of follow up drilling by Savage. Location of these drill holes have be verified as the collars are visible. Samples were assayed by SGS laboratory; however this cannot be verified as the original laboratory certificates are not available and were pre-JORC.Promesa have undertaken confirmation field sampling of Savage historical surface sampling which supports the original work undertaken

	 The assumptions used for any reporting of metal equivalent values should be clearly stated.	NA
Relationship between mineralisation widths and intercept lengths	 These relationships are particularly important in the reporting of Exploration Results.  If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.  If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’).	NA.
Diagrams	 Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.	NA
Balanced reporting	 Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.	Other exploration (mapping, geochemistry and geophysics work) data has been previous reported to the market by Promesa.
Other substantive exploration data	 Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.	Discussion of the Alumbre project geology is included within the release. Other exploration (mapping, geochemistry and geophysics work) data has been previously reported the market by Promesa.
