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

Align your credentials to specialty occupation standards
USCIS requires a geologist role to demand a specific bachelor's degree or higher. Pull the O*NET profile for Geoscientists to confirm the education and skill benchmarks your employer must document in the petition.
Target employers with active LCA filing history
Search Migrate Mate to filter for employers who have filed Labor Condition Applications for geologist roles. Prior DOL filings signal an employer already understands the H-1B1 Chile sponsorship process and won't stall at the paperwork stage.
Benchmark your offer against the DOL prevailing wage
Before accepting an offer, run the job title and location through the OFLC Wage Search. Your offered wage must meet or exceed the DOL prevailing wage for Level I through Level IV, depending on your experience.
Confirm your employer files the LCA before your interview
The consulate won't process your H-1B1 Chile application without a certified LCA. Verify the employer has submitted to DOL and received certification, typically within seven business days, before you schedule your consular appointment.
Negotiate visa fee responsibility into your offer
Unlike H-1B visa, USCIS does not adjudicate H-1B1 Chile petitions, so some employer-side filing costs differ. Clarify in writing which fees the employer covers and which fall to you before signing an offer letter.
Prepare fieldwork documentation if your role involves remote sites
Consular officers may probe whether a geologist role is office-based or field-based when assessing specialty occupation. Bring the job description, professional license if applicable, and a letter from the employer detailing site-specific technical duties.
Frequently Asked Questions
Does a geologist role qualify as a specialty occupation for the H-1B1 Chile visa?
Yes, geologist positions typically qualify because they require at least a bachelor's degree in geoscience, geology, or a closely related field. The employer must document this degree requirement in the Labor Condition Application and supporting job description. Roles that accept any bachelor's degree regardless of field may face scrutiny, so the job posting should specify the relevant discipline.
How does the H-1B1 Chile visa differ from H-1B for geologists?
The H-1B1 Chile visa has no lottery and no USCIS petition filing, which means geologists can apply directly at a U.S. consulate in Chile after the employer's LCA is certified by DOL. The annual cap sits at 1,400 visas and has not historically been exhausted. H-1B requires employer-sponsored USCIS filing, subjects you to the lottery, and carries significantly higher employer-side costs.
How do I find employers willing to sponsor the H-1B1 Chile visa for geologist positions?
Migrate Mate lists geologist roles from employers with documented LCA filing history, so you can identify companies already familiar with the H-1B1 Chile sponsorship process rather than cold-pitching employers who've never filed. Filtering by occupation code and visa type narrows results to realistic sponsorship opportunities rather than open listings with no sponsorship history.
Can I switch employers while on the H-1B1 Chile visa if I'm working as a geologist?
Yes, but the new employer must file a certified LCA with DOL before you can begin work for them. There is no USCIS portability provision for the H-1B1 Chile visa the way AC21 applies to H-1B holders. You'll also need to return to a U.S. consulate for a new visa stamp in the new employer's name, which typically requires scheduling an appointment in Chile.
Does fieldwork or remote site work affect my H-1B1 Chile visa sponsorship as a geologist?
Fieldwork doesn't disqualify a geologist from H-1B1 Chile sponsorship, but the employer must show that the position requires specialized theoretical and practical application of geoscience. If work occurs at multiple sites, the LCA must reflect the appropriate prevailing wage for each location where you'll regularly work, per DOL requirements.
