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

Search Mining & Natural Resources Jobs in ArizonaMining & Natural Resources E-3 Sponsorship Jobs in Arizona: Frequently Asked Questions
Which mining and natural resources companies sponsor E-3 visas in Arizona?
Arizona's largest mining employers, including Freeport-McMoRan, BHP, Rio Tinto, and Asarco, have histories of hiring international professionals for technical roles. These companies operate large copper and molybdenum projects across the state and regularly need geologists, mining engineers, and environmental specialists. E-3 visa sponsorship eligibility depends on the specific role, the employer's willingness to file a Labor Condition Application, and whether the position qualifies as a specialty occupation.
Which cities in Arizona have the most mining and natural resources E-3 sponsorship jobs?
Phoenix hosts corporate and administrative functions for many of Arizona's major mining companies, making it a strong market for engineering management and environmental consulting roles. Tucson is close to active copper mining operations in southern Arizona and supports geology and operations positions. Globe and Miami, situated in the copper-rich Tonto Basin region, are where many site-level technical and engineering jobs are located.
What types of mining and natural resources roles typically qualify for E-3 sponsorship?
Roles that typically qualify as specialty occupations under the E-3 include mining engineers, geological engineers, environmental engineers, hydrogeologists, metallurgists, and mine planning engineers. The position must normally require at least a bachelor's degree in a specific technical field. General labor, equipment operation, and roles without a defined degree requirement generally do not qualify. Your degree field must also align directly with the responsibilities of the offered position.
How do I find mining & natural resources E-3 sponsorship jobs in Arizona?
Migrate Mate is built specifically for Australian professionals seeking E-3 sponsorship in the United States and filters jobs by visa type, state, and industry. For mining and natural resources roles in Arizona, you can browse current openings from employers who have indicated E-3 sponsorship willingness. Searching by industry and location on Migrate Mate removes the guesswork of identifying which companies are open to sponsoring Australian candidates.
Are there any Arizona-specific considerations for E-3 sponsorship in mining and natural resources?
Arizona is one of the top copper-producing states in the country, which means mining operations here tend to be large-scale and capital-intensive, often backed by multinational companies familiar with international hiring and visa sponsorship processes. Many operations are in remote areas, so employers sometimes offer relocation support. State environmental regulations and EPA compliance requirements also drive consistent demand for environmental engineers and scientists, roles that align well with E-3 specialty occupation criteria.
What is the prevailing wage for E-3 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.
