## Minestarters Atlas summary

SSR Mining announced an updated Technical Report Summary for its Marigold Gold Complex in Nevada, outlining a 20-year life of mine plan based on expanded gold mineral reserves. The new plan increases gold reserves by 43% to 4.6 million ounces and includes a maiden life of mine plan for the Buffalo Valley project. The study projects an after-tax NPV5% of $3.3 billion and average annual gold production of 231,000 ounces from 2027 to 2031, with an All-In Sustaining Cost of $2,005 per ounce sold over the life of mine.

Reasoning: The updated Marigold Technical Report Summary significantly expands gold mineral reserves by 43% to 4.6 million ounces, establishing a 20-year mine life with a robust after-tax NPV5% of $3.3 billion, supported by S-K 1300 and NI 43-101 compliant reporting, despite a decrease in M&amp;I and Inferred resources.

- Positive factor: Significant increase in gold reserves \(43%\)

- Positive factor: Long mine life \(20 years total production\)

- Positive factor: Strong after-tax NPV5% of $3.3 billion

- Positive factor: Maiden life of mine plan for Buffalo Valley included

- Positive factor: High average annual gold production \(231 koz over 5 years\)

- Positive factor: S-K 1300 and NI 43-101 compliant reporting

- Positive factor: QP/CP signed off on the estimates

- Negative factor: Measured &amp; Indicated Mineral Resources decreased by 7.78%

- Negative factor: Inferred Mineral Resources decreased by 42%

- Negative factor: AISC of $2,005/oz is relatively high, though acceptable at current gold prices

Low confidence — this extraction should be reviewed alongside the original source.

## How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
