ASARCO Ray Mine is seeking an enthusiastic Mine Geologist to be part of a dedicated team focused on supporting copper production at a world class copper deposit. The Ray Mine Geologist plays a critical role in supporting safe and efficient ore extraction by providing accurate geological interpretation, ore boundary definition, and field validation at an autonomous haulage, high-tonnage open-pit copper mine, which processes both sulfide and oxide ores. Reporting to the Chief Mine Geologist, this position ensures that ore control decisions are informed by field observations and geological data, and that ore routing supports both Mine-to-Mill optimization and LSXEW leach material performance. The Mine Geologist is instrumental in linking and integrating geology with operations, planning, and metallurgy to drive site-wide value generation.
ROLE AND RESPONSIBILITIES
- Conduct detailed pit mapping, geologic logging, and sampling with focus on lithology, structure, alteration, and mineralization, ensuring accurate material classification.
- Define and update ore control polygons and ore/waste boundaries, ensuring sulfide and oxide ore are routed appropriately to mill, leach pad, or stockpiles.
- Support Mine-to-Mill initiatives by identifying rock characteristics that impact fragmentation, handling, and plant throughput, and communicating findings to Drill & Blast and Processing teams.
- Collaborate with the LSXEW and Metallurgy teams to optimize heap leach material selection, ensuring appropriate copper solubility, acid consumption, and mineralogy compatibility.
- Contribute geological insight to shovel placement and short-range production plans to minimize dilution and maximize recovery.
- Assist in the update of 3D operational geology models in Leapfrog Geo, under direction of the Chief Geologist, ensuring current pit conditions are reflected in planning inputs.
- Participate in grade reconciliation processes, comparing predicted vs. actual performance, identifying causes of discrepancies, and refining geological interpretations.
- Perform QA/QC of sampling procedures including blast hole logging, channel sampling, and data integrity reviews.
- Coordinate closely with Survey, Mine Engineering, and Operations to ensure geological guidance is actionable and aligned with the short-range mining schedule.
- Report findings and provide visualizations in daily/weekly production meetings and planning reviews.
- Ensure geological work and documentation adhere to international best practices, including conformity with U.S. SEC SK-1300 technical reporting standards as applicable.
- Ensure compliance with site HSE standards and promote safe fieldwork practices.
BASIC QUALIFICATIONS
- Bachelor's degree in Geology, Geological Engineering, or a related discipline
- 2+ years of open pit mine geology experience, preferably in porphyry copper systems
- Working knowledge of ore control methods and field validation for both mill-grade and leach-grade material
- Familiarity with Mine-to-Mill concepts, including fragmentation analysis and geometallurgical impacts
- Understanding of heap leach behavior, including copper solubility, oxide/sulfide transitions, and acid consumption trends
- Proficiency in geologic software (Leapfrog Geo, MinePlan, Vulcan, or similar)
- Strong observational skills and ability to work closely with cross-functional teams in field and office settings
- Effective communication and technical documentation skills
- Valid driver's license

Which mining and natural resources companies sponsor H-1B1 Chile visas in Arizona?
Arizona's copper-dominant mining industry includes large employers with documented H-1B1 Chile sponsorship activity, among them Freeport-McMoRan, BHP, and Rio Tinto, which operate significant open-pit and underground mines across the state. Smaller exploration and environmental consulting firms in the Tucson and Phoenix metro areas also sponsor H-1B1 Chile workers, though sponsorship practices vary by role, project cycle, and company size.
Which cities in Arizona have the most mining and natural resources H-1B1 Chile sponsorship jobs?
Tucson is the primary hub for mining and natural resources H-1B1 Chile sponsorship jobs in Arizona, given its proximity to major copper operations in the Santa Cruz and Pinal corridors. Phoenix hosts corporate and environmental consulting offices with sponsorship capacity, while smaller towns like Globe, Miami, and Bagdad are close to active mine sites where technical and engineering roles are concentrated.
What types of mining and natural resources roles typically qualify for H-1B1 Chile sponsorship?
Roles that typically qualify require at least a bachelor's degree in a directly related specialty field. In Arizona's mining sector, qualifying positions commonly include mining engineers, geologists, geochemists, metallurgical engineers, environmental scientists, and hydrogeologists. General labor, equipment operation, and trades positions generally do not meet the H-1B1 visa specialty occupation standard, as they do not require a specific theoretical or technical degree for entry.
How do I find mining and natural resources H-1B1 Chile sponsorship jobs in Arizona?
Migrate Mate filters job listings specifically for H-1B1 Chile visa sponsorship in Arizona's mining and natural resources sector, letting you search by occupation, employer, and location without sorting through roles that don't support your visa type. You can also cross-reference employer sponsorship history using DOL Labor Condition Application data, which Migrate Mate surfaces alongside listings so you can see which Arizona mining employers have actively filed for H-1B1 Chile workers.
Are there state-specific or industry-specific considerations for H-1B1 Chile sponsorship in Arizona's mining sector?
Arizona's mining operations are subject to federal and state environmental permitting requirements, which means roles tied to compliance, reclamation, and water rights are particularly active and often require the specialized academic credentials that satisfy H-1B1 visa specialty occupation standards. The state's heavy reliance on copper production also means hiring cycles can track commodity prices, so sponsorship activity from large operators may intensify during expansion phases and slow during periods of reduced output.
What is the prevailing wage for H-1B1 Chile mining & natural resources jobs in Arizona?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
