Off-Market Costa Rica Gold Mine Opportunity | High-Grade Lab Results | Qualified Review Available Confidential Off-Market Gold Mine Opportunity – Costa Rica An exceptional off-market mining opportunity is now available in Costa Rica, supported by recent geological documentation and third-party laboratory testing. The project includes a gold-bearing mine site with significant exploration upside and documented high-grade results. Recent July 2025 lab testing produced multiple strong gold values, including samples reported at 135.38 g/t, 204.63 g/t, 70.22 g/t, and additional samples above 20 g/t gold. Based on general gold ore grade references, ore exceeding 20 g/t is commonly classified as bonanza-grade material. The opportunity is further supported by documentation from a recognized Costa Rican geologist. The certification confirms that Franz Ulloa Chaverri is an active Emeritus member of the College of Geologists of Costa Rica, with professional authority covering mineralogical determinations and the prospecting and evaluation of mineralized areas. This is a rare chance for a qualified buyer, investor group, or mining operator to evaluate a Costa Rica-based gold project with compelling assay results and meaningful development potential. Highlights: Costa Rica gold mine opportunity Off-market and confidential Recent July 2025 gold lab results available Multiple samples tested at high-grade and bonanza-grade levels Geologist certification documentation available Strong upside for experienced mining operators, investors, or strategic partners Full document package available upon execution of NDA and buyer qualification Qualified buyers only. Proof of funds and signed NDA required prior to release of full details, location information, and supporting documentation. Please contact Frederick “Freddy” Antonelli for confidential discussion and next steps.
Southwest / Water Infrastructure & Environmental Services / Platform / ~$0.68MM Adj. EBITDA Company Overview The Company is a Southwest-based provider of water infrastructure maintenance and environmental services, specializing in the rehabilitation, monitoring, and ongoing operation of water wells and treatment systems for mining, municipal, and industrial clients. Operating from a centralized hub in Arizona, the business serves critical infrastructure across regional mining districts and municipalities, supporting essential water supply and regulatory compliance functions.  Founded in the late 1990s, the Company has established a leading regional position through deep technical expertise, long-tenured customer relationships, and a deliberate focus on maintenance and rehabilitation rather than capital-intensive drilling. This asset-light approach enables strong margins, high returns on capital, and consistent free cash flow generation.  The business generates highly predictable revenue through long-term operation and maintenance (O&M) contracts, which account for approximately 80% of total revenue. These contracts are tied to non-discretionary production and regulatory requirements, resulting in strong customer retention, with over half of clients maintained for more than 15 years.  Services are delivered through three integrated divisions: wellfield services, environmental contracting, and instrumentation & controls. The Company’s workforce is fully certified (OSHA, HAZWOPER, MSHA), and it maintains specialized licenses that create significant barriers to entry and limit competition.  The Company operates within a large and growing water infrastructure market, supported by structural tailwinds including aging infrastructure, groundwater depletion, and increased demand from mining and industrial activity, particularly in the Southwest.

Key diligence, valuation, financing, and transition considerations for buyers evaluating mining business acquisitions.
Get an independent reserve estimate before you value anything else. A mining or aggregates business is worth what it can extract and sell, and reserves are a depleting asset. Commission a qualified geologist or engineer to estimate proven and probable reserves and the permitted extraction area; the seller's optimism is not a substitute for measured tonnage.
Verify every mining, environmental, and zoning permit and its transferability. Extraction is governed by mining permits, environmental authorizations, and local zoning that limit how much, how deep, and how long you can operate, and these do not always transfer cleanly. Permitted reserves are valuable; unpermitted reserves may be worth very little.
Quantify the reclamation obligation and any required bonding. Most jurisdictions require operators to restore the site after extraction, and that obligation transfers with the business. Understand the estimated reclamation cost, the bonding in place, and whether it is adequately funded; an underestimated reclamation liability can turn a profitable operation into a long-term cash drain.
Map the haul radius, because aggregates do not travel far profitably. Sand, gravel, and crushed stone are low-value, heavy materials whose economics are dominated by trucking cost. A pit near growing construction demand with limited competing operations within haul distance has a durable advantage; a remote one does not.
Inspect the mobile and processing equipment and the deferred capital it hides. Crushers, screens, loaders, and haul trucks are expensive, wear hard, and signal how the business has been run. Assess condition, remaining life, and the capital expenditure a buyer will need to make; under-maintained equipment inflates current earnings at the cost of near-term capex.
Underwrite the regional construction and infrastructure cycle. Aggregates demand tracks roadbuilding, infrastructure spending, and local development, so a pit's fortunes are tied to its region's construction activity. Understand the demand drivers, any large committed projects, and the cyclicality, and price for a normal cycle rather than a construction boom.
