Accommodations
−Removed: mine site area camp maintains facilities which can accommodate 50 persons.
−Removed: The village of San José
−Removed: de Gracia maintains
−Removed: few stores, which offer only minimal goods.
−Removed: Camp Facilities
−Removed: DynaMéxico
−Removed: maintains an administrative and logistics office in Guamuchil, located 100 kilometers southwest of the SJG property.
−Removed: The SJG Project
−Removed: sources many of its supplies from Guamuchil, and from Los Mochis and Culiacan.
−Removed: A satellite dish installed at the SJG Property
−Removed: provides communications from the SJG Property to Guamuchil.
−Removed: field laboratory is maintained within the camp facility.
−Removed: The Company utilized the lab for assaying services during its production
−Removed: activities in 2003-2006.
−Removed: In the second half of 2016, the laboratory has been refurbished by DynaMineras and is currently utilized

−Removed: anticipates utilizing the lab facility in the future for providing internal assays to support the exploration, test mining, and
−Removed: pilot milling activities.
−Removed: Geology & Mineral Deposits
−Removed: de Gracia lies within the Sierra Madre Occidental (“SMO”) Gold-Silver Belt, in a second-order graben directly
−Removed: east of the regional-scale Grete Graben.
−Removed: The SMO is recognized as a highly prospective mineral belt for gold, silver and
−Removed: poly-metallic deposits.
−Removed: The basement to the Sierra Madre Occidental consists of deformed Paleozoic sedimentary strata, which are
−Removed: non-conformably overlain by Tertiary mafic to felsic volcanic and volcanoclastic strata known as the Lower Volcanic Series (“LVS”).
−Removed: Strata of the LVS are recognized as being spatially related to gold and silver mineralization in the region.
−Removed: sedimentary strata are capped by a thick sequence of non-deformed Late Tertiary ignimbrites, known as the Upper Volcanic Series
−Removed: (“UVS”).
−Removed: oldest rocks exposed at San José
−Removed: de Gracia are deformed Paleozoic shale, sandstone, conglomerate and minor limestone, which
−Removed: are non-conformably overlain by andesite and rhyodacite flows and tuffs of the LVS.
−Removed: Volcanic and sedimentary strata are
−Removed: cut by quartz-feldspar porphyry, porphyritic diorite bodies and fine-grained mafic dykes, which may be co-temporal with the LVS.
−Removed: Ignimbrites of the UVS are exposed at higher elevations on the property and are thought to act as a post mineralization
−Removed: cap rock, thereby indicating an Early to Mid-Tertiary (Paleocene to Eocene) age for gold mineralization at San José
−Removed: mapping within the project area has defined several stages of deformation, beginning with compression during the Laramide Orogeny
−Removed: which affected the Paleozoic basement and formed flat-lying reverse faults, which have been reactivated as conduits for gold-bearing
−Removed: fluids in the La Prieta trend.
−Removed: Extension in Tertiary time led to the development of second order structures, trending south,
−Removed: southwest and southeast;
−Removed: which formed the major structural orientations for mineralization at San José
−Removed: latest phase of deformation is characterized by late-stage extension and southwest tilting.
−Removed: Mineralization
−Removed: grade gold mineralization at San José
−Removed: de Gracia is found in vein structures hosted within andesite and rhyodacite of the
−Removed: Lower Volcanic Series (“LVS”) and underlying Paleozoic sediments as fault breccia veins and crackle breccias that
−Removed: exhibit multiple stages of reactivation and fluid flow, as evidenced by crustiform/colloform textures and cross cutting veins.
−Removed: Locally, veins exhibit sharp, clay gouge hanging wall and footwall contacts with slickensides, indicating reactivation of
−Removed: structurally-hosted veins subsequent to mineralization.
−Removed: Gold grades can also be carried within the mineralized halo adjacent
−Removed: to the principal veins as quartz-chlorite stockwork.
−Removed: In addition to vein-hosted mineralization, broad zones of un-mineralized
−Removed: clay alteration, developed southwest of the main mineralized trends, may overlie lower-grade, disseminated gold mineralization
−Removed: at San José
−Removed: de Gracia is laterally and vertically zoned from discrete zones of silicification to broad zones of illite
−Removed: to clay alteration with increasing elevation and/or distance from the main feeder structures.
−Removed: Faulting and tilting of the
−Removed: mineralization system have affected the surface distribution of alteration and in general has exposed deeper portions of the system
−Removed: in the northeast and exposed shallower, more distal portions of the hydrothermal system in the southwest part of the property.
−Removed: characterization of the mineralization at San Jose de Gracia can be described as low sulphidation polymetallic epithermal gold
−Removed: Six principal mineralized trends have been identified at San José
−Removed: de Gracia, from south to north.
−Removed: These consist of
−Removed: Purisima Ridge trend;
−Removed: Chinos trend;
−Removed: Parilla to Veta Tierra trend (Including San Pablo East);
−Removed: Prieta trend, and
−Removed: Hilos to Tres Amigos trend .

−Removed: (“Minop”),
−Removed: a subsidiary (or affiliate) of Goldgroup Mining Inc., built three dimensional solids to constrain estimation to the interpreted
−Removed: veins in each swarm.
−Removed: The 172 holes most recently drilled (2009-2011), were allocated as follows:
−Removed: Tres Amigos (64 holes), San Pablo
−Removed: (49 holes), La Union (24 holes), La Purisima (32 holes) and Argillic Zone (3 holes).
−Removed: The data base also includes rock and chip
−Removed: sampling, regional stream sediment sampling, and IP Surveys.
−Removed: total of 5,540 pieces of core were measured for specific gravity using the weight in air vs.
−Removed: weight in water method.
−Removed: This represents
−Removed: an additional 3,897 measurements taken in the 2009-11 drill seasons with density measurements taken from all mineral zones.
−Removed: samples were coated with paraffin wax before being measured.
−Removed: The results tabulated have been sorted by lithology and mineralized
−Removed: The average specific gravity of 5,051 wall rock samples was 2.59 while the average specific gravity for 489 samples of
−Removed: vein material is 2.68.
−Removed: CAM and Servicios y Proyectos Mineros have reviewed the procedures and results and opine that the results
−Removed: are suitable for use in mineral resource estimation.
−Removed: Resource Estimate - Construction of Wireframes-- Mineral Resources were estimated by Mr.
−Removed: Sandefur within wireframes constructed
−Removed: by technical personnel of Minop.
−Removed: Minop was contracted by Mineras de DynaResource S.A.
−Removed: (“DynaMineras”).
−Removed: Resource Estimate - Explanation of Resource Estimation-- Resource estimation was done in MineSight and MicroModel computer
−Removed: systems with only those composites that were inside the wireframe used in the estimate.
−Removed: Estimation was done using kriging with
−Removed: the omni-directional variogram derived from all the data in each area for gold using the relative variogram derived from the log
−Removed: High grades were restricted by capping the assays at a breakpoint based on the cumulative frequency curves.
−Removed: was done using search radii of 100 x 100 x 50 m “blocks”
−Removed: oriented subparallel to the general strike and dip of the
−Removed: vein system in each area.
−Removed: A sector search, corresponding to the faces of the search box with a maximum of two points per sector
−Removed: was used in estimation.
−Removed: A density of 2.68 based on within ‘vein density’
−Removed: samples was used in the resource estimate.
−Removed: Within each of the four areas there are approximately 20 to 40 veins in the vein swarm.
−Removed: Resources were estimated by kriging using
−Removed: data from all veins in the swarm.
−Removed: In general, gold accounts for at least 80% of the value of contained metal at the project, so
−Removed: the variograms for gold were used in estimation of the four other metals.
−Removed: veins at San Jose de Gracia have been historically mined for many years and historic mined volumes are not available.
−Removed: exception is the approximate 42,000 tonnes of ore processed by DynaMéxico during its pilot production activities in 2003-2006.
−Removed: The resource table is not adjusted for any historic mining.
−Removed: To validate that historic mining had not significantly reduced the
−Removed: resource, CAM reviewed the database for all assays greater than 1 gram per ton gold that were next to missing values at the bottom
−Removed: of drill holes.
−Removed: Only four assays satisfying this criterion were found, and on the basis of this review, Mr.
−Removed: Sandefur does not
−Removed: believe that significant mining has occurred within the volumes defined by the wireframes.
−Removed: y Proyectos Mineros performed a database review
−Removed: and considers that a reasonable level of verification has been completed, and that no material issues have been left unidentified
−Removed: from the drilling programs undertaken.

+Added: ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE AND PHYSIOGRAPHY
+Added: Topography, Physiography, and Vegetation
+Added: The topography of the San José de Gracia district is generally rugged with elevations varying from 400 meters in the valley bottoms to over 1600 meters in the higher Sierra.
+Added: A network of small roads and tracks winds around areas nearer the old workings at San José de Gracia.
+Added: Access to the remainder of the large property at the current stage of development is difficult without the use of horse or helicopter.
+Added: The SJG Project can be accessed by road, from either the City of Culiacan) or the City of Guamuchil.
+Added: Either route goes through the small town of Sinaloa de Leyva, then from Sinaloa de Leyva by gravel mountainous road to the village of San José de Gracia (population 250), which covers approximately 90 kilometers and is roughly a five hour trip.
+Added: The SJG Project can also be accessed by air.
+Added: A gravel airstrip is located adjacent to the San Jose de Gracia Village.
+Added: The airstrip is suitable for light aircraft and charter flights of 45 minutes duration are available from the cities of Los Mochis or Culiacan.

+Added: MINERAL PROCESSING AND METALLURGICAL TESTING
+Added: Bulk Sample, Hazen Process Development Metallurgical Report
+Added: Ore and existing mill tailings samples were collected under the supervision of Mr.
+Added: Henderson prior to DynaMexico’s acquisition and consolidation of San Jose de Gracia.
+Added: The ore samples consisted of a bulk (about 500 kg) of stockpiled ore from the lower adit of the Tres Amigos mine (intercept of the Tres Amigos and Orange Tree veins).
+Added: In addition, approximately 100 kg of ore as a bulk sample was taken from the surface at the Gossan Cap area.
+Added: Three additional ore samples (approximately 5-15 kg each) were assembled from splits of the cores from several of the 1997 drilling program core holes to develop samples representing different ore types for testing.
+Added: These included:
+Added: 1) composite drill cores from Palos Chinos, 2) massive sulphide from the Tres Amigos vein and 3) disseminated, non-sulphide mineralized zones at the bottom of several Tres Amigos core holes.
+Added: The logic was that major exploratory test work to define a metallurgical process would be done on the bulk sample from the adit at Tres Amigos and the other samples would have limited testing done at the selected metallurgical process conditions to verify the performance of the selected metallurgical process circuit on other types of San José mineralization.
+Added: Finally, several bulk samples (50-100 kg) of existing tailings from the Rosarito mill and the old Rosarito mill were collected and used to conduct flotation, gravity, and limited leachability test work on the tailings.” Samples were shipped to the laboratory of Carbonyx Carbon Technologies in Plano, Texas where in 2000 and 2001 two separate preliminary test programs were conducted, one for the tailings, and the other for a portion of the bulk Tres Amigos ore.
+Added: He developed a concept for the metallurgical processing to produce both gravity and flotation concentrates (rougher and cleaner).
+Added: The tests confirmed a metallurgical flow sheet to be utilized at San José to recover up to 90% of the feed gold into the concentrates.
+Added: The above “in-house” testing established a preliminary flowsheet for a mill circuit for processing either primary ore or for reprocessing the existing tailings.
+Added: Subsequently Hazen Research Laboratories of Golden, Colorado (“Hazen”) was engaged to provide independent verification of the in-house work, and carry out additional optimization test work.
+Added: Lockwood Greene/ Mr.
+Added: Henderson prepared and verified completion of the scope of work.
+Added: In summary, various interim reports and the final metallurgical report, the "Official Hazen Test Report, (“Hazen Report”)” provided results as follows:
+Added: (a) The initial gravity beneficiation/flotation test work on the Tres Amigos and Gossan Cap bulk ore samples were very encouraging with up to 80 % recovery of the feed gold into the gravity concentrates while maintaining a minimum concentrate grade of 100 g Au/t ;
+Added: (b) The existing tailings samples (feed grades of 3 -8 g Au/t) returned similar recovery results, but had to be cleaned to produce a final concentrate with > 100 g Au/t ;
+Added: (c) The overall gold recoveries into the gravity cleaner concentrate still were in excess of 50% of the total feed gold;
+Added: (d) Flotation tests on primary ore samples resulted in recoveries of 85 - 90 % of the feed gold into the rougher concentrates, however, recoveries after cleaning (to get > 100 g Au/t grade) dropped to the 65-75 % range;
+Added: (e) A combination circuit of a gravity pre-concentration stage with flotation on the gravity tailings indicated the potential to recover > 90% of the feed gold into the gravity concentrate, the rougher flotation and the cleaner flotation concentrates while maintaining a 100 g Au/t grade in all of the concentrates.”
