Where you will be working
Resolution Copper has the potential to supply nearly 25% of the US copper demand and create several thousand direct and indirect jobs in the Pioneer Mining District of Arizona, with an economic value of several billion dollars over the estimated mine life.
The project will rely on a technique called block caving to extract the deposit that lies more than 2,000 meters deep. This technique uses gravity to help remove the ore and is the most viable way to recover the resource.
Resolution Copper will continue underground development, conduct extensive drilling and orebody testing, plus maintain the permitting and public engagement process.
About Rio Tinto
Rio Tinto is a leading global mining and materials company. We operate in 35 countries where we produce iron ore, copper, aluminium, critical minerals, and other materials needed for the global energy transition and for people, communities, and nations to thrive.
We have been mining for 150 years and operate with knowledge built up across generations and continents. Our purpose is finding better ways to provide the materials the world needs – striving for innovation and continuous improvement to produce materials with low emissions and to the right environmental, social and governance standards. But we can’t do it on our own, so we’re focused on creating partnerships to solve problems, create win-win situations and meet opportunities.

How to Get Visa Sponsorship in Geologist
Confirm your degree qualifies for STEM OPT
Geology, geophysics, earth science, and hydrogeology degrees are typically on the STEM OPT designated program list. Verify your specific CIP code with your DSO before applying, since the extension depends on your program classification, not just your job title.
Apply before your OPT start date
Many geology roles require background checks, field safety certifications, or clearance processes that take weeks. Start applications at least two months before your OPT begins so you can start work on time without gaps in your authorization period.
Highlight fieldwork and technical software skills
Employers sponsoring OPT geologists expect proficiency in ArcGIS, Petrel, or RockWorks alongside field mapping experience. Lead with these credentials in your resume and cover letter to differentiate yourself and signal readiness to contribute immediately.

Get Access To All JobsFrequently Asked Questions
Do geology degrees qualify for the 24-month STEM OPT extension?
Yes, most geology and geoscience degrees qualify. The STEM OPT extension applies to degrees on the DHS STEM Designated Degree Program List, which includes geology, geophysics, hydrology, and earth sciences. Your eligibility depends on your program's CIP code, not just the degree title. Confirm with your DSO before applying, since some interdisciplinary programs use CIP codes that fall outside the STEM list.
Can I work for an environmental consulting firm or government contractor on OPT?
Yes, both are common employers for OPT geologists. Government contractors can hire OPT students for most geology roles, though positions requiring security clearances may be restricted to U.S. citizens or permanent residents. Environmental consulting firms frequently hire geologists on OPT and have experience with the STEM extension and subsequent H-1B sponsorship. Review the clearance requirements in any job posting before applying.
Where can I find Geologist jobs from employers open to OPT sponsorship?
Migrate Mate is the recommended platform for OPT students searching for geologist roles. It filters jobs by visa sponsorship willingness, saving you from applying to positions where OPT authorization is a non-starter. This is especially useful for geoscience roles, where sponsorship policies vary widely between large energy companies, smaller environmental firms, and government contractors.
Does working in the field or at remote sites affect my OPT compliance?
Field-based geology work is permitted on OPT as long as the employer who authorized your employment remains the same and the work is related to your degree. If your role requires extended assignments with a third-party client site, confirm that your DSO has the correct employer of record on file. Misreporting your work location or employer can create compliance issues during future visa applications.
What happens to my OPT status if my geology employer reduces my hours or changes my role?
OPT requires that your employment be directly related to your degree and that you work at least 20 hours per week. If your employer reduces you to fewer than 20 hours or reassigns you to work unrelated to your geoscience degree, your OPT compliance is at risk. Report any material changes to your DSO within 10 days. If employment ends, you have a 90-day unemployment allowance across your total OPT period.
