History
A Texas rare earths explorer funded Round Top through small raisings, handed control to partner USA Rare Earth, and was absorbed by it in August 2026.
2011-2013: Funding Round Top
The company, then called Texas Rare Earth Resources, set out to advance its Round Top project in Hudspeth County, Texas. In February 2011 it closed a $2.0 million private placement, bringing that round to $4 million, and gave an investor a four-month option to buy up to 3,200,000 more shares at $2.50. Investors exercised options for 3,040,000 shares on May 31, raising $7,600,000, and for a further 3,200,000 shares on June 9, raising $8,000,000. Together the exercises brought in $15,600,000 and left 33,836,259 shares outstanding. The company said this covered its expected $16-18 million of needs through 2012 and let it speed up drilling and metallurgical testing (lab work on extracting the metals). Each exercise also came with new five-year warrants, which meant more potential dilution.
In June 2012 it furnished a Preliminary Economic Assessment for Round Top, an early study of the project's potential. The excerpt gave no figures. In March 2013 it took over a state surface lease covering 54,990.11 acres in Hudspeth County from Southwest Range & Wildlife Foundation. The price was $500,000 cash, 1,063,830 shares and ten annual $45,000 payments for Rio Grande Basin conservation. An updated assessment followed in December 2013, again with no figures stated in the filing.
2014-2015: Small raisings and a technology bet
The record for 2014 is quiet. In January 2015 the company closed a rights offering, selling 4,272,270 units at $0.22 for about $940,000. Each unit carried one share and two warrants, intended for the Round Top hydrometallurgy plan (extracting metals using liquids) and general costs.
In July 2015 it formed a joint venture, ReeTech, LLC, with K-Technologies to develop an ion exchange method of extracting rare earths. The company held 2.79% after paying $391,000 and could earn up to 49.9% by contributing up to $7.0 million. In December 2015 it raised about $659,500 from 3,297,500 units at $0.20, and settled two $40,000 notes and $10,000 of lease payments by issuing units. The filing said the June 2015 $45,000 payment to Southwest had not been paid.
2016-2021: Handing over Round Top
The record is quiet for most of these years, and the beats do not explain the later share growth. The ReeTech venture's fate is not stated after 2015. In May 2021 the Round Top assets were placed into Round Top Mountain Development, LLC, owned 80% by USA Rare Earth (successor to Morzev, which held the 2018 option) and 20% by the company. USA Rare Earth was to contribute about $3,761,750 in cash and the Pilot Plant, and owed the company $3 million if it exercised its option for a further 10%. The company would be diluted if it failed to fund cash calls.
In November 2021 its subsidiary Standard Silver Corp. signed an agreement with Santa Fe Gold to explore a silver property of about 1,300 acres in Grant County, New Mexico. Greentech Minerals Holdings agreed to fund an exploration and feasibility study estimated at about $6.5 million in return for a share of the joint venture.
2022-2026: Final years and the merger
In June 2023 the Round Top agreement was amended so that if the company missed its cash calls, USA Rare Earth could cover the gap and the company's stake would shrink, though not below 3%. In May 2024 the silver agreement was widened to about 1,600 acres, and a drilling permit application was reported with about 55 holes planned. The filing did not mention Greentech.
In February 2025 the company borrowed $1,098,000 through interest-free convertible notes, partly from directors and their relatives, with warrants attached. By early August 2025 all the notes had converted into 3,660,000 shares at $0.30. In February 2026 the remaining 8,880,000 warrants were exercised without cash payment, producing 6,187,472 shares.
On March 4, 2026 the company agreed to be acquired by USA Rare Earth, Inc., its Round Top partner. Shareholders were called to vote on July 28, 2026. The merger closed on August 7, 2026: each share became 0.043279843 of a USA Rare Earth share, based on 88,339,693 fully diluted shares and 3,823,328 USAR shares in total. The company was merged into DyTb, LLC, a USA Rare Earth subsidiary, and its directors and officers stepped down. The Santa Fe silver agreement was terminated, and the shares left the OTCQB. By August 20, 2026 the company had deregistered its securities, ending its duty to report to the SEC. It no longer exists as an independent company.
