Previous Technical Work at the Cinco de Mayo Project

The Upper Manto Pb-Zn-Ag (Au) deposit consists of two parallel and overlapping manto deposits referred to as the Jose Manto deposit and the Bridge Zone. The Project also hosts the Pozo Seco Mo-Au deposit. The two deposits host distinctly different mineralization with different commodities, are separated by four kilometres, and are divided by a small mountain range. At the Project, extensive amount of historical technical work has been completed by MAG between mid-2004 and 2012. The work included geological mapping, geochemical sampling, geophysical surveys, surface drilling (approximately 213,591 m in 445 drill holes), and metallurgical testing.

An independent technical report and Mineral Resource estimate (“MRE”) on the Upper Manto deposit was prepared in 2012 (the “2012 Historical MRE”), by Roscoe Postle and Associates (“RPA”), which is now part of SLR. RPA estimated the Mineral Resources for the Upper Manto deposit using drill hole data available as of September 1, 2012. At an NSR cut-off of US$100/t, Inferred Mineral Resources were estimated to total 12.45 million tonnes (“Mt”) at 132 g/t silver (“Ag”), 0.24 g/t gold (“Au”), 2.86% lead (“Pb”), and 6.47% zinc (“Zn”). The total contained metals in the resource were 52.7 million ounces (“Moz”) of Ag, 785 million pounds (“Mlb”) of Pb, 1,777 Mlb of Zn, and 96,000 ounces (“oz”) of Au. This 2012 Historical MRE for the Upper Manto deposit is summarized in Table 1.

Table 1: 2012 Historical Mineral Resource Estimate for the Upper Manto Deposit

Class	Tonnage	Gold	Silver	Zinc	Lead	AgEq	Gold	Silver	Zinc	Lead
	(Mt)	(g/t)	(g/t)	(%)	(%)	(g/t)	(oz)	(Moz)	(Mlb)	(Mlb)
Inferred	12.45	0.24	132	6.47	2.86	385	96,000	52.7	1,777	785
Note: Estimates by David Ross, P. Geo., of RPA (Ross 2012). Mineral Resources were estimated at an NSR cut-off value of US$100 per tonne. NSR values are calculated in US$ using factors of $0.60 per g/t Ag, $12.32 per g/t Au, $18.63 per % Pb and $14.83 per % Zn. These factors were based on metal prices of US$27.00/oz Ag, US$1,500/oz Au, $1.15/lb Pb, and $1.20/lb Zn and estimated recoveries and smelter terms. The Mineral Resource estimate used drill hole data available as of September 1, 2012. CIM Definition Standards have been followed for classification of Mineral Resources.

In 2010, RPA prepared an independent technical report and Mineral Resource estimate for the Pozo Seco deposit based on drill results available as of July 12, 2010 (the “2010 Historical MRE”). At a cut-off grade of 0.022% Molybdenum (“Mo”), the Indicated Mineral Resources were estimated at 29.1 Mt grading 0.147% Mo and 0.25 g/t Au, containing 94.0 Mlb of Mo and 230,000 oz of Au. Inferred Mineral Resources were estimated at 23.4 Mt grading 0.103% Mo and 0.17 g/t Au, containing 53.2 Mlb of Mo and 129,000 oz of Au. The estimate was constrained within a preliminary pit shell using assumed costs, recoveries, and metal prices. This 2010 Historical MRE for the Pozo Seco deposit is summarized in Table 2.

Table 2: 2010 Historical Mineral Resource Estimate for the Pozo Seco Deposit

Class	Tonnage	Molybdenum	Molybdenum	Gold	Gold
	(000 t)	(%)	(lb)	(g/t)	(oz)
Indicated	29,066	0.147	94,012,000	0.25	230,000
Inferred	23,376	0.103	53,250,000	0.17	129,000
Note: Estimate by David Ross, P.Geo., of Scott Wilson RPA (Ross, 2010). The cut-off grade of 0.022% Mo was estimated using a Mo price of US$17/lb and assumed operating costs and recoveries. CIM Definition Standards have been followed for classification of Mineral Resources.

The reader is cautioned not to treat these historical Mineral Resource estimates disclosed in Table 1 and Table 2 above, or any part thereof, as current Mineral Resources or Reserves, nor should they be relied upon. However, they are included here as an indication of mineralization on the Project. The QP has not completed sufficient work to classify both Upper Manto and Pozo Seco as current Mineral Resources and Apollo is not treating them, or any part of them, as current Mineral Resources.

Apollo does not intend to complete additional work at Pozo Seco to update the historical Mineral Resource estimate in the foreseeable future and all future field work activities and proposed work would only occur once Apollo has obtained social license, and necessary permits for the Project. The Technical Report recommends that a significant exploration budget is warranted at the Upper Manto deposit. Recommended work includes additional drilling to expand the mineralized domains along strike and down dip, collect density data, and construct a geological model to improve confidence in the mineralization controls. The 61.6 m intersection of massive sulphide known as the Pegaso Zone, was not included in the historical estimate at the Upper Manto deposit and additional drilling is also recommended to establish the geometry of this zone during the first phase. The Technical Report recommends that as part of a Phase 2 program, Apollo prepares a current Mineral Resource estimate on the Upper Manto deposit.

Cinco de Mayo Transaction Terms

On September 20, 2024, Apollo entered into an earn-in and option agreement with MAG and its subsidiary MPS, pursuant to which Apollo was granted the option (the “Option”) to acquire all of the issued and outstanding shares of 0890887 B.C. Limited (“089 Limited”), a wholly owned subsidiary of MAG. MPS is (except for one share that is owned Los Lagartos S.A. de C.V., who holds such share for the benefit of MAG, in order to comply with the minimum legal requirement of having two shareholders in a Mexican corporation) an indirect, wholly-owned subsidiary of 089 Limited and the sole registered and beneficial owner of the Project. In order to render the Option exercisable, and to acquire a 100% indirect interest in and to the Project, Apollo must first obtain the necessary licensing and permits to access and conduct mining activities on the Project, followed by completing no less than 20,000 m of exploration drilling within five years. Upon completion of these terms and subject to the final approval of the TSX Venture Exchange, Apollo must then issue to MAG such number of common shares in the capital of Apollo equivalent to 19.9% of the then issued and outstanding common shares of the Company on a non-diluted basis following such issuance. In addition, Apollo will grant MAG the right to maintain its 19.9% stake by participating in any subsequent financing for an additional four-year period from the date of exercise of the Option.

During the Option term, the Company will control all exploration and development activities on the Project and will be responsible for all expenses associated with maintaining the Project in good standing.

About Cinco de Mayo Project

The Project is located in the north central part of Chihuahua State, Mexico approximately 190 kilometres northwest of the state capital of Chihuahua City in the Municipio de Buenaventura. The Project area is located immediately west of the village of Benito Juárez and benefits from excellent access via local gravel roads.

The Project is prospective for and hosts carbonate replacement type deposits including the Upper Manto Pb-Zn-Ag (Au) deposit, which consists of two parallel and overlapping manto deposits referred to as the Jose Manto and the Bridge Zone.

A potential new discovery, called the Pegaso Zone was not included in the 2012 Historical MRE. Apollo’s technical team considers this intersection as a high priority target that has potential to be a significant new discovery. The Company’s initial review of historical data suggests that the Pegaso Zone could indicate a larger and higher-grade resource at depth.
