The project lies in the trend known as the Mojave-Sonora Megashear, which hosts several significant gold deposits of the orogenic type. The El Mundo project has seen limited development, including minor production during the 1930s, and excavation of small pits and a 25-metre inclined shaft in the 1990s. The project was visited by Fresnillo PLCs exploration team, which took 72 chip samples on the project. Fresnillos samples reported an average of 2.93 g/t Au. No drilling has been conducted on the property. Following the above considerations, a core-drilling program consisting of six 200-metre holes (total 1,200 m) test the El Mundo and Jany veins. The program should cost an estimated US$378,000. A Phase II drilling program would follow contingent on the results of the Phase I drilling. 2.0INTRODUCTION **** This report provides an independent evaluation of the exploration potential of the El Mundo project, which is comprised of two mining concessions covering 100 hectares.

Toms Ramrez reports good relations with the surface owner and expects to execute formal surface-use and access agreements in the near future. ` 4.1.3 Environmental Liabilities The project has no known environmental liabilities. 4.1.4 Environmental Permitting The applicable regulation, Norma 120-SEMARNAT-2011*, requires a report, *Informe Preventivo en Materia de Impacto Ambiental*, that includes descriptions of the ground surface, mining/exploration history, surface ownership, mineral tenure, and the proposed exploration program. Certified written permission from surface owners must accompany the report when tendered to the Secretariat of Environment and Natural Resources (SEMARNAT) delegation in Hermosillo. There is no known or anticipated obstacle to obtaining the SEMARNAT authorization for the El Mundo project. 4.1.5 Mining taxes Mexican law requires that owners of mining concessions pay taxes semi-annually, in January and July of each year that a mining concession is valid. Taxes are calculated on a perhectare basis; the per-hectare tax amount goes up with the age of the concession as shown in Table 4.2. The basic per-hectare tax is adjusted for inflation annually. Semi-annual taxes for the El Mundo project are presented in Table 4.3. Failure to pay taxes will lead to revocation of a mining claim following a 30-day grace period/warning from the Mexican Mines Department. Table 4.2. Semi-annual Mexican mining tax rates, commencing in 2022. Base per-hectare rates are adjusted annually for inflation. | Years of concessions existence | Per hectare tax rate 2022 | | | from issue of concession title | MXN$ | | | During years 1 and 2 | $8.63 | | | During years 3 and 4 | $12.91 | | | During years 5 and 6 | $26.68 | | | During years 7 and 8 | $53.66 | | | During years 9 and 10 | $107.31 | | | After 10th year | $188.86 | | Table 4.3.

Assessment work filings are due in May based on work executed during the prior calendar year. Minimum amounts to be spent on a concession are determined on a per-hectare basis, in addition to a fixed amount per concession. The fixed amounts and the per-hectare amounts go up with the size of the concession, and with the age of the concession as illustrated in Table 4.4. A concession owner may apply past excess expenditures to a subsequent years filings. Table 4.4. Mexican assessment work minimum amounts for 2022.

The project lies 78 km southeast of Sonoyta, Sonora and Lukeville, Arizona (the nearest US port of entry) (Figures 4.1-4.2). The El Mundo project lies in the Sonora-Mojave Megashear portion of the Basin and Range geological province, which is host to several significant gold-mining districts, including Mezquite, American Girl, and Cargo Muchacho in California, USA; and La Cholla, La Herradura, El Chanate, and San Francisco, in Sonora, Mexico. 4.3 El Mundo project ownership The Amalia concession is owned 100% by Toms Ramrez Lpez and the El Mundo concession is owned 100% by Ral Fernando Lemus Pompa, with full power of attorney granted to Toms Ramrez Lpez. The author of this report has not verified the legal status of the El Mundo mining concessions, nor the ownership of the surface, but relies on the verbal description of ownership, supplied by Toms Ramrez L. 5.0 ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE, AND PHYSIOGRAPHY **** The El Mundo project lies in northwestern Sonora, on the boundary of Caborca and Altar Municipalities, 75 km northwest of Caborca, Sonora, and 80 km southeast of the border communities of Sonoyta, Sonora and Lukeville, Arizona (Figures 4.1 and 4.2). Elevations within the El Mundo claim block range from 730 to 780 m. Vegetation is typical of the Sonoran Desert. The annual average temperature is 22C. Average low temperatures range from 5C in December January to 23C in June-July. High temperatures average 21C in December-January and 41C in June-July. The record high temperature for Caborca is 48C. The Caborca area is very dry, with precipitation averaging about 31 mm annually. The route taken to the project for the authors visit in February 2021 was on Mexican Highway 2 from northwest from Caborca to a dirt road turnoff about 78 km from Caborca. From Highway 2, follow a dirt road to the northeast for about 20 km to Rancho La Manteca, then turn southeast to the project. Caborca, with a population of approximately 12,000, is the nearest town to the El Mundo project. Caborca has airport, rail, and road access, as well as labor, equipment, and service requirements for conducting exploration or mining-related activities. ******** 6.0 HISTORY 6.1 Early work The first workings at El Mundo were carried out in the 1930s by an American prospector who extracted approximately 20,000 tonnes of ore. The project saw no significant work from that period until Ral Lemus P. began his investigations in the 1980s. Lemus is said to have conducted geological, mining, and metallurgical work during that time, but no records are available. 6.2 Ramrez In the mid-1990s, Ing Toms Ramrez L. acquired the project and excavated shallow pits over 750 m along the El Mundo vein, including a 25 m-deep shaft (Figure 6.1). The mineralized structure was cut by the shaft at a depth of 6 meters. * Figure 6.1. Hoist structure of inclined shaft on El Mundo vein. Ing. Toms Ramrez, property owner, poses. 6.3 Mexican Geological Survey, 1990s-2000s geological mapping The Mexican Geological Survey published a geological map of the project region at 1:250,000. The Survey identified the El Mundo mineralized zone as one of several northeasttrending shear/vein zones (Servicio Geolgico Mexicano, 2002) (Figure 7.3). 6.4 Fresnillo 6.4.1 Mapping and sampling Fresnillo traced the El Mundo vein for 750 m and the Jany vein for 250 m. Both veins strike NE/SW and dip 50 degrees to the SE. Fresnillos rock-chip samples on the veins assayed an average of 2.93 g/t Au. Fresnillo describes discontinuous boudinaged veins with silica and boxwork alteration halos less than 1 m wide, emplaced in upper Cretaceous granite and granodiorite. Fresnillo geologists collected 72 chip samples on the veins. Gold assays are presented in Table 6.1; their locations are shown in Figure 6.1). 6.4.2 Potential resource estimate (NON-43-101 COMPLIANT) Fresnillo listed a **non 43-101-compliant** potential resource of 33,500 troy ounces of gold: 22,000 tr oz Au above a depth of 100 m in the El Mundo vein 4,000 tr oz Au above 100 m in the Jany vein 7,300 tr oz Au above 100 m, disseminated in host rocks Table 6.1. Fresnillo rock-chip samples, El Mundo project. See Figure 6.1 for sample locations. | SAMPLE | UTM east | UTM north | Au g/t | | SAMPLE | UTM east | UTM north | Au g/t | | | 1-A | 379642 | 3470944 | 5.5 | KN-002-18 0062 | 379554 | 3470881 | 8.7 | | | 2-A | 379649 | 3470960 | 5.5 | KN-002-18 0063 | 379555 | 3470881 | 3.8 | | | 3-A | 379660 | 3470974 | 5.75 | KN-002-18 0064 | 379551 | 3470874 | 1.8 | | | 4-A | 379669 | 3470985 | 5 | KN-002-18 0065 | 379517 | 3470874 | 0.4 | | | 5-A | 379692 | 3471006 | 5 | KN-002-18 0066 | 379478 | 3470805 | 1.5 | | | 5-B | 379698 | 3471013 | 3.5 | KN-002-18 0067 | 379417 | 3470713 | 1.3 | | | 6-A | 379710 | 3471024 | 5.5 | KN-002-18 0068 | 379322 | 3470633 | 0.2 | | | 7-A | 379721 | 3471042 | 2.5 | KN-002-18 0069 | 379378 | 3470697 | 0.5 | | | B | 379726 | 3471051 | 1.25 | KN-002-18 0070 | 379835 | 3470919 | 0.9 | | | 8-A | 379731 | 3471062 | 4.25 | KN-002-18 0071 | 379708 | 3471031 | 0.5 | | | 9-A | 379750 | 3471081 | 3.3 | KN-002-18 0072 | 379745 | 3471079 | 2.6 | | | 10-A | 379779 | 3471114 | 9.75 | KN-002-18 0073 | 379826 | 3471189 | 3.4 | | | 11-A | 379557 | 3470884 | 7.25 | CH-019-001 | 379862 | 3470931 | 2.58 | | | B | 379554 | 3470888 | 6.62 | CH-019-002 | 379839 | 3470922 | 3.91 | | | 12-A | 379550 | 3470886 | 2.5 | CH-019-003 | 379836 | 3470920 | 0.63 | | | 13-A | 379550 | 3470882 | 4.75 | CH-019-004 | 379831 | 3470916 | 0.08 | | | B | 379569 | 3470897 | 1.87 | CH-019-005 | 379783 | 3470888 | 4.04 | | | 14-A | 379550 | 3470879 | 3.5 | CH-019-006 | 379736 | 3470855 | 0.53 | | | 15-A | 379548 | 3470877 | 6.75 | CH-019-007 | 379666 | 3470820 | 0.22 | | | 16-A | 379540 | 3470876 | 1 | CH-019-008 | 379659 | 3470813 | 0.48 | | | 17-A | 379535 | 3470868 | 3.75 | CH-019-009 | 379653 | 3470807 | 0.06 | | | 18-A | 379501 | 3470833 | 0.5 | CH-019-010 | 379638 | 3470799 | 0.44 | | | 19-A | 379482 | 3470810 | 0.5 | CH-019-011 | 379623 | 3470791 | 2.21 | | | 30-A | 379619 | 3470926 | 12.5 | CH-019-012 | 379603 | 3470777 | 2.54 | | | 31-A | 379620 | 3470928 | 17.75 | CH-019-013 | 379591 | 3470767 | 1.18 | | | KN-002-18 0051 | 379667 | 3470983 | 1.1 | CH-019-014 | 379583 | 3470763 | 0.41 | | | KN-002-18 0052 | 379665 | 3470980 | 1.2 | CH-019-015 | 379577 | 3470763 | 0.36 | | | KN-002-18 0053 | 379665 | 3470980 | 0.4 | CH-019-016 | 379554 | 3470749 | 1.22 | | | KN-002-18 0054 | 379633 | 3470938 | 7.1 | CH-019-017 | 379522 | 3470725 | 1.29 | | | KN-002-18 0055 | 379595 | 3470914 | 4.1 | CH-019-018 | 379497 | 3470703 | 0.36 | | | KN-002-18 0056 | 379595 | 3470914 | 3 | CH-019-019 | 379503 | 3470703 | 0.01 | | | KN-002-18 0057 | 379609 | 3470982 | 4.9 | CH-019-020 | 379598 | 3470492 | 0.13 | | | KN-002-18 0058 | 379595 | 3470918 | 1.2 | CH-019-021 | 379679 | 3470531 | 1.55 | | | KN-002-18 0059 | 379594 | 3470919 | 0.5 | CH-019-022 | 379644 | 3470530 | 0.16 | | | KN-002-18 0060 | 379595 | 3470918 | 0.8 | CH-019-023 | 379323 | 3470586 | 0.08 | | | | CH-019-024 | 379384 | 3470679 | 1.05 | | Figure 6.1.

Geologic provinces of Mexico, showing location of La Reyna project. Northwestern Sonora records the early development of the southwestern edge of the North American craton, with a possible accreted Jurassic volcanic arc terrane. Regional metamorphism is associated with several intrusive and orogenic episodes, followed by Basin and Range-style rifting (Figure 7.1). The Mohave-Sonora Megashear strikes northwest through the region; it has played an important role in the formation of mineral deposits in the region (Campbell, et al., 1998; Jacques and Clark, 1998) (Figure 7.2). Figure 7.1. Location of the El Mundo project in relation to the Mojave-Sonora Megashear and existing gold mines of the Sonora gold belt. The oldest rocks in the region, Precambrian schist, gneiss, amphibolite, and quartzite of the Caborca terrane, are commonly cut by slightly younger latite and diorite intrusions (Anderson and Silver, 1979). Caborca terrane rocks may be correlated with slate and greenschistgrade metamorphic rocks found in portions of northeast Sonora and the Pinal schist of Arizona (Jacques and Clark, 1998). Rocks unconformably overlying Upper Proterozoic sedimentary rocks consist of shallow marine clastic and carbonate units deposited along the margins of the North American craton. Sedimentation continued through much of the Paleozoic across northwestern and eastern Sonora, with several recognizable breaks and units that have been correlated with the Paleozoic sediments of the Colorado Plateau (Jacques and Clark, 1998). Crustal shortening in Late Mississippian and Late Permian-Early Triassic along the craton margin juxtapose deeper water sediments with shallow water and clastic sediments. In eastern Sonora, continental sediments were deposited during the Triassic in contrast to the marine deposits that accumulated in northwestern Sonora (Jacques and Clark, 1998). Volcanism began during the Jurassic; these volcanic rocks occur along the northern segment of the Sonora gold belt as well as in the Caborca terrane (Merriam and Eells, 1979; Molina, et al., 1998). Upper Jurassic-Lower Cretaceous sedimentary rocks include the Bisbee Group, which is widespread throughout southern Arizona and northern Sonora. The Bisbee Group rocks consist of the Glance Conglomerate, Morita Formation, the Mural Limestone and the Cintura Formation (Jacques, 1995). These units were deposited in a coastal to shallow marine environment with some deeper-water facies identified in eastern Sonora. The Upper Cretaceous El Chanate Group unconformably overlies the Bisbee Group and consists of continental sediments with some intercalated volcanic rocks (Jacques, et al., 1990). The type section for the El Chanate Group is in the Sierra El Chanate, approximately 10 km northeast of the La Gloria project, where it ranges from 750 m to more than 2,800 m thick (Jacques, 1993). At its type section, the El Chanate Group has been subdivided into the Pozo Duro, Anita, and Escalante formations, from oldest to youngest. The Pozo Duro Formation consists of red mudstone and shale with intercalated tan sandstone and conglomerates. The Anita Formation consists of andesite breccias, fluvial conglomerates, sandstones and mudstones, and an upper unit that contains tan shales and gray limestone. Nourse (2001) suggested that the El Chanate Group may in fact underlie the Bisbee Group and therefore be Jurassic. The Upper Cretaceous Tarahumara Formation consists of andesite breccias, flows and tuffs that are equivalent to the El Charro volcanic complex (Jacques, 1993) and unconformably overlie the older rock units. Tertiary volcanic units consisting of rhyodacite to rhyolite flows, tuffs, and breccias intercalated with basalts and andesites are relatively uncommon in northwestern Sonora, and are more common in eastern and southern Sonora where they are the equivalent of the plateauforming sequences in the Sierra Madre Occidental (Roldan and Clark, 1992). Upper Tertiary sediments accumulated in some of the extensional basins that developed in the Parallel Ranges and the Buried Ranges west of Caborca. Some of these contain borate deposits and are intercalated with upper Tertiary volcanic flows and breccias (Miranda et al., 1998). Upper Tertiary volcanic rocks consist of thin basalt flows, cinder cones and tuffs, particularly in the Pinacate volcanic field (Gutman and Sheridan, 1978). Quaternary alluvial, eolian and talus deposits cover much of the region and commonly form a pediment cover that obscures bedrock. The depth to bedrock is not well known and ranges from a few metres to more than 200 m near Caborca and up to 1,100 m thick along the coastal plain west of Hermosillo (Verdugo, 1983). Pleistocene and Quaternary erosion and alluvial sedimentation have formed vast pediment cover and veneers throughout the region, including extensive fill among the Buried Ranges. Intrusive rocks include anorogenic granites of 1,460-1,410 Ma within the Precambrian terranes and the Abio granite found in the Caborca terrane (Jacques and Clark, 1998). Several plutons and hypabyssal intrusive phases occur within the Jurassic volcanic arc sequence and include calc-alkaline batholithic phases emplaced during the 90-40 Ma interval (Damon, et al., 1983). Two-mica granites were emplaced in 40-36 Ma; these are spatially associated with part of the Ancochi Batholith, and are present at the La Colorada mine (Zawada, 1998). The tectonic development of northern Sonora includes late Mississippian and Late Permian to Early Triassic thrusting of Paleozoic sedimentary rocks, middle to Late Jurassic leftlateral displacement along the Mohave-Sonora Megashear, Cretaceous Sevier-style thrusting, and Late Cretaceous Laramide-style thrusting with northeast vergence (Jacques and Clark, 1998). The Cenozoic tectonic events are characterized by the development of core complexes and low-angle detachment faults in the mid-Tertiary (Nourse, et al., 1994; Nourse, 1995), younger Basin and Range normal faulting and the formation of the Gulf of California in the Late Miocene to Pliocene (Sedlock, et al., 1993). 7.2 District geology Mexican Geological Survey mapping suggests that the El Mundo mineralized area is characterized by NE-trending shear/vein zones cutting upper Cretaceous batholithic(?) granite and granodiorite (Figure 7.3). Tertiary volcanic rocks, mainly rhyolite and rhyolite tuff, locally overlie the batholithic rocks. Lower elevations have varying thicknesses of late Cenozoic unconsolidated conglomerate and alluvium. **** **** Figure 7.3. El Mundo district geology (Servicio Geolgico Mexicano, 2002). 7.3 El Mundo project geology **** 7.3.1 Host rocks **** Granite and granodiorite, probably of batholithic extent, host the NE-SW-striking, SEdipping veins at El Mundo.

Red lines are concession boundaries. 7.3.3 Alteration Boxwork and quartz veinlets and strong silicification, carbonate veining, and sericitization form halos up to 1 m around wider portions (quartz boudins) of the veins. **** **** ` 7.3.3 Mineralization Gold mineralization at El Mundo occurs principally in two quartz-carbonate veins, the 750 m-long El Mundo vein and the 250 m-long Jany vein. Veins range in thickness from 0.5 to 1.5 m. Both veins strike NE-SW and dip 50 degrees to the southeast (Figures 7.5 and 7.6). A third vein, the Luna vein, was traced for 40 m by Fresnillos geologists in the southern part of the project area (Fresnillo, 2020). As noted in section 6.4.1, the average grade of chip samples taken by Fresnillo was 2.93 g/t Au. **** Figure 7.5. El Mundo vein in shallow cut, looking NE. Note ~50-degree dip to SE. Figure 7.6. Close-up of El Mundo vein shown in Figure 7.5. Note Fe oxide after pyrite. 9.0 DEPOSIT TYPES **** 8.1 Orogenic gold The Mojave-Sonora Megashear, a broad NW-striking structural zone, and northeastverging regional thrusts and associated tear faults in the northwestern portion of the zone are hosts to numerous gold mines characterized by low-grade (1-2 gpt gold), micron size, disseminated mineralization (Silver and Anderson, 1974; Jacques and Clark, 1998). Deposit types include veins and breccias, discontinuous quartz veins, a carbonate sedimentary-hosted deposit and several structurally controlled deposits. Mineralization is hosted by a wide range of rock units, including Proterozoic gneiss, Paleozoic sedimentary rocks, Late Jurassic granitic rocks, and Cretaceous clastic and carbonate units (Jacques and Clark, 1998). Recent erosion of pre-existing terrains and alluvial deposits have resulted in locally extensive Late Tertiary placer gold deposits near Caborca (Jacques and Clark, 1998; Southworth, J.R., 1905. The gold deposits in northwestern Sonora are found along or adjacent to the MohaveSonora Megashear, as shown in Figure 7.1, including several mines that are located along projections of this trend in the United States, including Picachos, Mesquite, and American Girl. At Picachos, the gold deposit is related to Mid-Tertiary age mineralization in a detachment fault setting, with mineralization hosted by brecciated upper-plate rocks and faults associated with a low-angle normal fault. Red-coloured Tertiary conglomerate and volcanics formed the upperplate host rocks, and chloritic breccias and gneissic or crystalline rocks constitute the lower plate lithologies. Mineralization at Mesquite has been interpreted to be a detachment type with a possible genetic affiliation with a two-mica granite. Gold mineralization occurs in quartz veins that are spatially associated with granitic dikes and lenses emplaced within a complex metamorphic host of high-grade gneissic rocks. Mineralization at La Herradura occurs in mylonitic and sheared gneiss and schist along high-angle structures, similar to those described at Mesquite (de la Garza, et al., 1998). Shear zones and intersections with shallow-dipping faults and mylonitic zones associated with regional deformation are the primary controls of gold mineralization at La Choya and El Chanate. At La Choya, the mineralization occurs in K-altered biotite granite and sediments adjacent to a thrust fault (Summers and Hufford, 1998), in low-angle anastomosing and stacked shears and sub-conformable quartz-carbonate veins and lenses. Ductile to semi-brittle deformation occurs along the principal thrust faults. Sulfide content in the ore zone is low (Thoms, 1998). At El Chanate, mineralization is reported to be controlled by a regional high-angle strikeslip fault striking N65W (San Jose fault) where it intersects one or more gently dipping thrust zones. Both structures are mineralized; but nearby low-angle Mid-Tertiary detachment faults and related breccias are commonly not mineralized. Subsidiary or higher-level thrust-fault zones of varying thicknesses crop out. They confirm that sheared and semi-brecciated structures were important for ground preparation prior to gold deposition (Clarke, 2005). The WNW-striking San Jose fault at El Chanate appears to be the primary vertical conduit for mineralization. It is characterized by abundant quartz veining parallel to its strike and in tensional quartz veins that strike northwest. In addition, there are erratically distributed arrays of high-angle quartz veins and sulfide hydrofractures that strike ENE to EW within this zone. The direction of these features and compressional character to mineralized structures suggest a late Mesozoic or Laramide age of mineralization. The presence of light-coloured dikes intruding the San Jose fault zone, several kilometres to the southeast, suggest a possible genetic relationship between these intrusives and mineralization. The dikes are cut by gold-bearing quartz veins and appear to be auto-altered, resulting in a crumbly, sugary textured mass of granulated quartz. Where fresh, the dikes are distinguishable as a feldspar porphyry with rare visible white quartz grains (Clarke, 2005). Many of the prospects and gold mines in the Mojave-Sonora Megashear region are associated with low-angle faults and mylonitic zones and high-angle sheared fault zones. Felsic dikes appear to be genetically associated with mineralization. The vein mineral assemblage and fluid inclusion data from some of these deposits suggest that they are mesothermal systems (Albinson, 1989; Zawada, 1998). Deposits such as La Herradura, Mesquite, San Francisco and El Chanate and the Canasta Dorada property are characterized as gold only deposits or orogenic gold deposits and lack any strong trace element signatures as is commonly associated with base metal or epithermal systems (de l Garza, et al., 1998). The age of mineralization appears to be late Mesozoic or Laramide (Jacques and Clark, 1998). Table 8.1.

Post-mineral rhyolite and rhyolite tuff overlie the intrusive rocks. Three veins have been identified at El Mundo, the El Mundo, Jany, and Luna veins, that have been traced for 750 m, 250 m, and 40 m, respectively. Historic sampling by Fresnillo averaged 2.93 g/t Au. Sampling by the qualified person confirmed gold and silver mineralization associated with the veins. ******** 26.0RECOMMENDATIONS A 1,200-metre diamond drilling campaign is recommended for the El Mundo project, based on the Fresnillo proposal described in section 6.4.3 of this report (holes EM-01-06). The drilling would test the El Mundo and Jany veins at depths 100-200 m down dip from surface exposures. Depending on the results of the program, a second phase of drilling may be recommended.
