Found in Algeria in 2021. <a rel="noreferrer nofollow">MetBull</a>: “This is a unique pallasite type both in terms of olivine composition and oxygen isotopes. Along with Milton, this meteorite is the only other ungrouped that is not a pyroxene pallasite, however Milton and this meteorite are not paired and do not have olivine compositions and oxygen isotopes that are similar. The modal abundances are approximately 60% metal, 38% olivine, 2% troilite.”

And Carl Agee of UNM just presented a <a href="https://www.hou.usra.edu/meetings/metsoc2022/pdf/6428.pdf" rel="noreferrer nofollow">new paper</a> suggesting it might be from an acapulcoite/lodranite-like parent body: “HeB 002 clearly possesses all the textural characteristics of a pallasite, however it has unique characteristics that set it distinctly apart from the Pallasite Main Group (PMG), the Eagle Station Group (ESG), as well other ungrouped or anomalous pallasites. For example, its oxygen isotope values occupy a location in triple oxygen isotope space that is different from other known pallasites. Interestingly, HeB 002 oxygen isotope values are coincident with the acapulcoite-lodranite group, suggesting a possible genetic link. HeB 002 also has olivine compositions that are more magnesian than any other known pallasite (Fa7.6±0.1, Fe/Mg=0.082±0.001) with the lowest Fe/Mn values (24±1) ever reported in pallasite olivine. These HeB 002 olivine values resemble the more magneisn members of the acapulcoite- lodranite group as well as olivines in winonaites. Chromite elemental values in HeB 002 also appear to be anomalous with respect to other pallasites. In particular Fe/Mn and Al/Cr values are among the lowest ever reported in pallasite chromite. In the case of HeB 002, an acapulcoite/lodranite-like parent body seems plausible and more work is needed on HeB 002 to further test this hypothesis.”
