SUMMARY

The visit from the 28th to the 30th of March, 2016 has the following objectives •Review the area to identify zones favorable to containing free gold and to continue refining with the equipment available at the site (immediately) •Zones favorable to containing mineralization deposits (short term) •Develop an integral exploration program to evaluate the veins and deposits (short to medium term) The El Álamo Mining District is one of the most important gold-bearing mineral deposits in Baja California North, in which prospecting and mining has long been developed, principally for gold but also very important placers, which to date are worked primarily in artisanal form, panning soils and river sediments. The mines only were worked in zones of higher grade and the maximum depth explored in wells, both inclined and vertical, of 20 to 50 meters, but there are mines such as The Princess with developments greater than 100 meters; one of the main reasons for leaving this district was flooding problems due to lack of pumping in mines and the poor conditions of work sites, all work sites, are currently inaccessible. In the areas known as El Álamo and La Biznaga, which include the mining concessions totaling 3000 hectares that is the property of AIVN DE MEXICO SA DE CV, veins of quartz are observed as principal structures, with brownstone anomalies generated by the oxidization of iron mineral that can be associated with broad zones of dispersed mineralization; as well we have mines known as La Princesa and La Aurora where the vein, of irregular thickness between 0.2 and 1.0m, is observed superficially; the gold content, according to reports of CRM 1976 is reported by the majority of the mining works to be on the order of 1 to 200 g/t, in the form of small mineralized inclusions throughout the structure. It is very common to observe the gold in the zones corresponding to the mineralized inclusions that contained a higher concentration of sulfur, those which by way of oxidation and leaching leave cells or box Works in which can be observed free gold. Equipment is currently available at the site (drum and Knelson concentrator with a capacity of 60 tph) to continue gold panning activity that was suspended in 2014 with a production of 500 tpd

El Álamo is located

between the

geographic coordinates

31°36”N latitude and

116°04”W longitude,

with principal access

from the Ensenada -

San Felipe highway,

which intersects a

branch to the SW at 91

Km, which in turn

connects with the town

of El Álamo at 18 Km;

the trip requires an

estimated time of 1.3

hours. The site

includes a landing strip

that is currently

unavailable.

El Álamo

The geologic and structural characteristics of the El Álamo mining district can be considered simple up to a certain point, since the study area is comprised of the granitic batholith of Baja California, by formations whose composition varies from granodiorite to quartz-diorite, from hornblende to biotite, of an age corresponding to the upper Cretaceous; it is common to observe the impact of dikes of different compositions, which are well considered both before and after the veins.

Note Based on operating 12 hour shifts 6 days per week 26 days per month, the metallurgical recovery will depend on the concentration of gold to be confirmed by assay, granulometric analysis, continuity of the operation and the condition of the equipment as well as the economic recovery will be a function of the price and net liquidation including point of entry and cost of delivery.

Conclusions ● Excavations in 25 meter grid to obtain samples and assign gold concentration to the resource

estimated at 272,700 metric tons in the Encampment and Biznaga stream, 130 samples in total.

● Semi-detailed mapping of areas of interest both for gold panning and to explore dispersed

deposits from which gold can be recovered by gravimetric concentration requires obtaining 100

samples distributed in the color anomalies mentioned in the area of encampment and Biznaga

● As well as the chemical analysis of the samples, a rated granulometric analysis is required to

improve the operating parameters of both the drum and the Knelson.

● The execution of the sampling and semi-detailed mapping for the areas mentioned requires 12

days. The topographic map of the mining concessions to be elaborated with contours at

minimum every 10 meters. The startup cost of the equipment currently unavailable as well as the

best distribution and location of the equipment to be carried out by a specialist who will be

recommended.

● The maps of mineral concessions assigned to AIVN DE MEXICO are required immediately, and to

know who surrounds these concessions or if they are free and we determine which are of interest

to immediately claim.

● To obtain the permission of the owners of lands where we are going to work in the areas of

interest mentioned, both for gold panning and for exploration of dispersed deposits.

● To investigate the permits before SEMARNAT (Secretary of the Environment and Natural

Resources) to obtain information on the streams, if you think it necessary.

● It is important to put the Knelson concentrator in operation since the coarse gold in the feed is

that which produces a good recovery

● A lower counterpressure of water generates a better recovery; its reduction permits the

concentration of finer gold particles given the lower force of the water current

● The water provided by the San David shaft section 2x2.5 meters and 90 meters deep is located at

650 meters from the encampment and requires gauging to determine if it is sufficient for the

process which requires a minimum of 17 m3/hour of clean water, 204 m3 in the 12 hours of daily

operation.

● The granulometry of the material and/or mineral feed is the most important variable (rated

granulometric analysis)

Page 14: The Álamo Project - nebula.wsimg.com

Conclusions ● The economic sensitivity analysis of gold panning - the best results are with the Knelson controlling

the variables such as granulometry, constant feed and counterpressure of water; the concentration

of 0.30 gr/ton in this analysis is information estimated by Eduardo Baoullosa and would require

determination of the sale price per ounce.

● The increment in the margin of the Knelson vs. the drum is the recovery; 65% vs 45% respectively

The estimated total cost of the work described for a second visit of the project is US$ 11,760,

59% of which are the analysis of the 230 samples shown in table 1.
