Irving, Texas--(Newsfile Corp. - April 3, 2025) - DYNR-DynaResource, Inc. (OTCQX: DYNR) ("DynaResource" or "the Company") is pleased to announce recent metallurgical test work results undertaken at its San Jose de Gracia mine in Mexico as part of the preparation of an SK 1300 Technical Report. These metallurgical test work results also support the capital improvement programs being undertaken to increase the overall gold recovery (from the low to mid-70 %) at San Jose de Gracia. This work program includes the re-establishment of a primary gravity gold circuit with the installation of three new Falcon gravity concentrators. These Falcon gravity concentrators will be installed after the Ball mills to recover the significant portion of free gold available in the San Pablo, San Pablo Sur and La Mochomera mining zones (see Figure 1).

The metallurgical test work results from three fresh rock composite samples from the active exploration areas of San Pablo, San Pablo Sur, and La Mochomera show excellent recovery >95% in all samples using gravity followed by flotation (using standard industry reagents). Additionally, gravity gold recoveries reached up to 33.8%, confirming that the gold mineralization is amenable to conventional gravity gold processing methods such as Falcon concentrators. The summary of the metallurgical test work results is tabled below.

Table 1: Results from the metallurgical test work (gravity followed flotation) completed from the three active mining areas. Note the grind size for the samples tested was 80%, passing 80 microns using standard industry reagents.

Rohan Hazelton, CEO of DynaResource commented, "This metallurgical work is important data for the upcoming SK1300 Technical Report Pre-Feasibility Study that we plan to release in early Q2 2025. I am pleased to see such incredibly high gold recoveries from each of our major gold zones defined to date. Better than 95% gold recovery means our ore is easily processable and this supports our planned re-installation of the gravity gold circuit at San Jose de Gracia. During the period 2015 to 2019 the gravity circuit at San Jose recovered 31% of the gold, and with an operating gravity circuit in the third quarter 2025, we anticipate an improvement in overall gold recoveries to approximately 80%."
